APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 8
EXECUTIVE SUMMARY<br />
The U.S. Department of Agriculture (USDA), Animal and Plant Health Inspection Service (APHIS),<br />
Veterinary Services (VS) conducted a risk analysis as a decision-making tool for a proposal to<br />
initiate trade in fresh pork from the <strong>Brazil</strong>ian State of Santa Catarina. Trade in fresh pork and other<br />
susceptible animals and products from Santa Catarina has not been allowed because USDA<br />
considers all of <strong>Brazil</strong> to be a country affected with foot-and-mouth-disease (<strong>FMD</strong>), swine vesicular<br />
disease (SVD), classical swine fever (CSF), and African swine fever (ASF).<br />
APHIS has evaluated information submitted by <strong>Brazil</strong> and conducted a site visit to Santa Catarina in<br />
June 2008 to substantiate the information reported in the documentation and add any new data.<br />
APHIS also conducted three other site visits to other <strong>Brazil</strong>ian States in 2002, 2003, and 2006. The<br />
site visits focused on the veterinary and legal infrastructure, border control procedures, laboratory<br />
and diagnostic capabilities, biosecurity procedures on swine farms, animal health recordkeeping<br />
systems, movement controls, and disease surveillance systems. APHIS’ analysis was based on<br />
information gathered from the site visits; on information submitted in writing by the <strong>Brazil</strong>ian<br />
Ministry of Agriculture, Livestock and Food Supply (MAPA) and the Companhia Integrada de<br />
Desenvolvimento Agricola de Santa Catarina (CIDASC); and on published scientific literature.<br />
This document describes the animal health system and disease control and eradication measures in<br />
the <strong>Brazil</strong>ian State of Santa Catarina. It identifies potential areas of risk and discusses how this risk<br />
is mitigated. The following factors were considered relevant in determining the disease status of<br />
Santa Catarina:<br />
No <strong>FMD</strong> outbreaks have occurred in Santa Catarina since 1993.<br />
Santa Catarina has not vaccinated against <strong>FMD</strong> since May 2000.<br />
No outbreaks of ASF have occurred in Santa Catarina since 1981.<br />
No outbreaks of CSF have occurred in Santa Catarina since 1990.<br />
SVD has never occurred in <strong>Brazil</strong>.<br />
Surveillance programs in cattle and swine have not detected the presence of the <strong>FMD</strong>, CSF, SVD, or<br />
ASF viruses in Santa Catarina. There was no evidence of <strong>FMD</strong> viral activity in cattle during or after<br />
the 2000-2001 and 2005-2006 outbreaks in other areas of the country. In addition, Santa Catarina<br />
does not vaccinate for <strong>FMD</strong>, so any cattle or swine in that State exposed to the <strong>FMD</strong> virus can be<br />
considered sentinels for the disease.<br />
APHIS considers the legal framework, animal health infrastructure, movement and border controls,<br />
diagnostic capabilities, surveillance programs, and emergency response systems within Santa<br />
Catarina adequate to detect and control <strong>FMD</strong>, CSF, SVD, and ASF outbreaks. Although the<br />
consequences of <strong>FMD</strong>, CSF, SVD, and ASF outbreaks are severe, APHIS considers the likelihood of<br />
outbreaks occurring in the United States, through exposure of domestic livestock to swine or other<br />
susceptible species or their related unprocessed products imported from Santa Catarina, to be very<br />
low.<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 9
I. BACKGROUND<br />
<strong>Brazil</strong> has officially requested that APHIS review the disease status of Santa Catarina to initiate<br />
trade in fresh pork from that State. Trade in fresh pork or other susceptible animals and products<br />
from Santa Catarina has not been allowed because APHIS considers <strong>Brazil</strong> to be a country affected<br />
with <strong>FMD</strong>, SVD, CSF, and ASF. The last outbreak of <strong>FMD</strong> in Santa Catarina occurred in 1993. No<br />
new <strong>FMD</strong> outbreaks have been reported since then, despite the occurrence of <strong>FMD</strong> in neighboring<br />
States in 2000-2001 and 2005-2006. <strong>Brazil</strong> has recognized Santa Catarina as free of CSF since<br />
1991, and ASF since 1981. <strong>Brazil</strong>ian authorities report that SVD has never occurred in <strong>Brazil</strong>.<br />
Historically, rinderpest virus has never become established in North America, Central America, the<br />
Caribbean Islands, or South America. A brief incursion into <strong>Brazil</strong> occurred in 1921 but was limited<br />
in scope and quickly eradicated.<br />

MAPA animal health officials submitted documentation to support their request. APHIS made a site<br />
visit to Santa Catarina in June 2008 to verify and complement the information submitted by <strong>Brazil</strong>.<br />
It focused on the legal framework and veterinary infrastructure, border and movement controls,<br />
agricultural practices, and laboratory diagnostics and surveillance programs related to Santa<br />
Catarina’s animal health program.<br />
Objective<br />
This is an analysis of the risk of introducing <strong>FMD</strong>, CSF, SVD, and ASF into the United States<br />
through importation of susceptible species and related unprocessed animal products from Santa<br />
Catarina (because rinderpest has never been established within the continent it will not be addressed<br />
further within this document). The risk analysis is intended as a decision-making tool for APHIS<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 10
managers that will allow APHIS to develop appropriate regulatory conditions with mitigations that<br />
address disease introduction risks posed by any initiation of trade. It also constitutes an information<br />
source for APHIS stakeholders, providing justification for the conditions in the rule. The analysis<br />
focuses on Santa Catarina’s status and control measures for <strong>FMD</strong>, SVD, CSF, and ASF.<br />
Supporting Data<br />
The analysis is based on documentation provided by MAPA, observations made by the site visit<br />
teams, and published information. The report incorporates data obtained from a site visit to Santa<br />
Catarina in 2008 and previous site visits in 2002, 2003, and 2006 to different areas of <strong>Brazil</strong>. The<br />
visits evaluated the risk of importing fresh (chilled or frozen), maturated, deboned beef into the<br />
United States. The scope of the 2002 site visit included verification of <strong>FMD</strong> outbreak controls, an<br />
overview of the surveillance program and laboratory capabilities, vaccination practices and<br />
eradication activities, and movement and border controls within <strong>Brazil</strong>. During this visit, APHIS<br />
placed particular focus on the regional <strong>FMD</strong> situation in <strong>Brazil</strong> and South America and on the risk of<br />
reintroducing <strong>FMD</strong> into <strong>Brazil</strong> from neighboring countries. The focus of the 2003 site visit was to<br />
collect data that APHIS used in our risk assessment. The focus of the 2006 site visit was to evaluate<br />
the <strong>FMD</strong> situation following the 2005 and 2006 outbreaks in the States of Mato Grosso do Sul and<br />
Paraná. The scope of the 2008 site visit was to evaluate the status of Santa Catarina with respect to<br />
freedom from <strong>FMD</strong>, CSF, ASF, and SVD.<br />
Hazard Identification<br />
APHIS has identified several World Organization for Animal Health (OIE) listed diseases [1] as the<br />
primary hazards associated with initiating trade in animals and animal products from foreign regions.<br />
APHIS addresses listed foreign animal diseases of primary concern in our regulations at title 9, Code<br />
of Federal Regulations (9 CFR), Part 94. APHIS is obligated to evaluate the status of a given region<br />
or country for specific foreign animal diseases before opening trade in susceptible species and<br />
related products with that region or country (9 CFR 92.2) [2].<br />
The hazards identified for this analysis are <strong>FMD</strong>, CSF, ASF, and SVD. Epidemiological<br />
characteristics of the disease agents relevant to the import risks they may pose are described in the<br />
Annexes.<br />
<strong>Risk</strong> Analysis<br />
This analysis has four components: the release assessment, the exposure assessment, the<br />
consequence assessment, and the risk estimation. These components are defined in OIE guidelines<br />
and represent the international recommended components for animal health import risk analyses.<br />
Release Assessment<br />
For the purpose of this report, release assessment refers to the evaluation of the likelihood that <strong>FMD</strong>,<br />
CSF, SVD, and ASF exist in Santa Catarina and, if so, the likelihood that these diseases could be<br />
introduced into the United States through imports of susceptible animals or their products from Santa<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 11
Catarina. The report includes an in-depth evaluation of the 11 factors identified by APHIS in 9 CFR<br />
section 92.2 to consider in assessing risk levels of free regions. Those factors are:<br />
1. The authority, organization, and infrastructure of the veterinary services organization in the<br />
region.<br />
2. Disease status.<br />
3. The status of adjacent regions with respect to the agent.<br />
4. The extent of an active disease control program, if any, if the agent is known to exist in the<br />
region.<br />
5. The vaccination status of the region.<br />
6. The degree to which the region is separated from adjacent regions of higher risk through<br />
physical or other barriers.<br />
7. The extent to which movement of animals and animal products is controlled from regions<br />
of higher risk, and the level of biosecurity regarding such movements.<br />
8. Livestock demographics and marketing practices in the region.<br />
9. The type and extent of disease surveillance in the region.<br />
10. Diagnostic laboratory capacity.<br />
11. Policies and infrastructure for animal disease control in the region, i.e., emergency<br />
response capacity.<br />
<strong>Risk</strong> factors are identified from the information gathered on these topics, and applicable mitigations<br />
to address those risk factors are discussed.<br />
<strong>Evaluation</strong> of Information Provided by MAPA and CIDASC Relevant to the 11 Factors<br />
Outlined in 9 CFR 92.2<br />
Assessing the likelihood of introducing <strong>FMD</strong>, CSF, SVD, and ASF into the United States requires an<br />
evaluation of the relevant characteristics of the exporting regions relative to the epidemiology of the<br />
diseases. The 11 factors in APHIS’ regionalization rule, described above, provide a context for<br />
evaluating the risk of exporting a foreign animal disease from a defined region into the United<br />
States. This section of the risk analysis describes APHIS’ evaluation of these factors for Santa<br />
Catarina.<br />
Main Findings:<br />
1. Authority, organization and infrastructure of the veterinary services<br />
The authority, organization, and infrastructure of the veterinary services must be clearly documented<br />
to provide confidence in the ability of the country to monitor for disease, oversee veterinary<br />
activities, and implement disease controls in the region (i.e., control risk). This section is designed<br />
to provide a comprehensive view of the human, financial, physical, and regulatory resources<br />
available within MAPA and CIDASC. The section describes the legal authority for animal health<br />
activities in the region, the organizational structure and function of the veterinary services, and the<br />
personnel and financial resources available.<br />
Legal Authority<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 12
Legal authority for animal disease control in <strong>Brazil</strong> primarily consists of general legal directives and<br />
regulations issued by the Federal government with the States issuing supplementary legal acts. The<br />
primary animal health services law in <strong>Brazil</strong> is contained in Decree No. 24.548, enacted in 1934 [3,<br />
4]. There are several overlapping laws administered at both the Federal and State levels in Santa<br />
Catarina which establish, among other things, controls on animal and product imports, disease<br />
control, farm security, surveillance, risk classification, movement control, animal identification, and<br />
funding [4].<br />
The main law that defines the veterinary medicine profession in <strong>Brazil</strong> is Law No. 5517. This law<br />
established the Federal and regional veterinary medicine councils that govern activities and<br />
professional aspects of veterinary medicine. Currently, there are over 40,000 veterinarians in <strong>Brazil</strong><br />
with the majority being in the southeast (47 percent) and south (23 percent) parts of the country.<br />
Official services veterinarians are required to participate in specific training programs for different<br />
sanitary programs. More than 500 veterinarians have been trained specifically in exotic animal<br />
diseases, including <strong>FMD</strong> [5].<br />
Organization of the Official Veterinary Services<br />
Federal and State authorities provide the two main structures for <strong>Brazil</strong>’s veterinary services.<br />
MAPA, through the Department of Animal Health (DDA), is the main Federal authority for all<br />
animal health programs and is responsible for coordination of all aspects of the national animal<br />
health system. MAPA has regional offices, called the Federal Agriculture Supervision (SFA) in all<br />
26 States in <strong>Brazil</strong> in addition to central offices located in the Federal District. A Federal<br />
veterinarian resides in each regional office and oversees compliance with all official animal health<br />
activities at the State level [4, 6, 7].<br />
The State Veterinary Services implements animal health programs with the private sector. The State<br />
Agricultural Secretariat (SDA) offices coordinate field activities. The coordinating agency directly<br />
responsible for administration of field activities is an integrated public company referred to as<br />
Companhia Integrada de Desenvolvimento Agricola de Santa Catarina (CIDASC). Field services<br />
are carried out by the staff of the local veterinary units (LVUs), which are further coordinated by the<br />
regional veterinary offices [8].<br />
At the international level, <strong>Brazil</strong> has an agreement to form a Permanent Veterinary Committee<br />
(Comite Veterinaria Permanente – CVP) composed of the four Mercosur countries (Argentina,<br />
<strong>Brazil</strong>, Paraguay, and Uruguay) plus Bolivia and Chile. This committee is working to improve<br />
international relations and collaboration on disease eradication activities (see<br />
www.panaftosa.org.br/GIEFA/documentos/Doc2_Ing.DOC).<br />
Central Competent Authority<br />
The Federal Government coordinates and supervises the overall animal health programs, develops<br />
disease control strategies, regulates and controls international commerce in animals and animal<br />
products, registers and controls vaccines, conducts laboratory diagnosis, audits State veterinary<br />
services, inspects animals and animal products for import, and conducts training. Federal<br />
government officials, located primarily in Brasilia, develop policies, laws, and regulations that<br />
govern all animal health programs and activities [6].<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 13
Programs managed by the Federal authorities include <strong>FMD</strong> eradication, swine health (especially<br />
managing CSF), tuberculosis (TB) and brucellosis management, transmissible spongiform<br />
encephalopathy (TSE) surveillance, biological residue control, and traceability. To provide effective<br />
oversight, MAPA officials travel regularly to the Ministry’s offices in each State, and to the SDA<br />
offices in the field to evaluate programs at the local level [6].<br />
The Federal veterinary service workforce consists of 1,629 veterinarians, 2,037 technical assistants,<br />
and 358 administrative assistants [9].<br />
State and Local Veterinary Services<br />
Federal and State interactions are well defined and structured. State personnel execute Federal<br />
programs, laws, and policies at the State level. Cooperation is achieved by renewal of signed<br />
cooperative agreements, which transfer considerable amounts of funding from the Federal budget to<br />
State agencies. The Federal program has ultimate authority over conduct of the national eradication<br />
program. It uses its authority to allocate financial resources to ensure compliance with Federal<br />
program policy and provides oversight to ensure that the resources provided will be effectively<br />
managed [6, 7, 10].<br />
Responsibilities of State officials for carrying out Federal programs are outlined in standard<br />
operating procedures developed with Federal officials. The standard operating procedures apply to<br />
defined regions and reflect local circumstances. In Santa Catarina, CIDASC implements Federal<br />
programs at the field level. It maintains an up-to-date register of rural holdings, controls intra- and<br />
interstate movement of animals and animal products, provides assistance to Federal authorities<br />
during outbreaks, investigates suspected notifiable diseases, provides sanitary education to the<br />
community, develops animal disease surveillance and information systems, inspects livestock events<br />
such as fairs, exhibitions, auctions and public sales, and inspects animals and their products and<br />
byproducts before movement. The SFA of MAPA oversees these activities [4].<br />
Regional and local offices of the official State veterinary services are part of the CIDASC<br />
organization. The central and regional units of CIDASC oversee local animal health activities. The<br />
work of CIDASC is directly inspected by MAPA, through its representatives at SFA. Additionally,<br />
MAPA carries out audits throughout the State, with the last statewide evaluation occurring during<br />
August and September of 2006. The evaluation was positive overall and the State adopted the<br />
auditors’ recommendations (Personal communication, Chapeco Office).<br />
During the 2008 site visit, the Chapeco Regional Office reported that it had been audited by either<br />
MAPA (for pigs and poultry) or CIDASC three times over the past year. The last <strong>FMD</strong> audit in<br />
Santa Catarina was conducted in 2006, with favorable overall results. A few deficiencies were<br />
documented, including the need for a single person in charge of sanitary health (since at the time one<br />
person oversaw both sanitary and animal health). These deficiencies have been corrected.<br />
Each State in <strong>Brazil</strong> is administratively divided into municipalities, which comprise the basic units<br />
of animal health and surveillance. The field structure of the veterinary services in the country<br />
consists of 1,528 LVUs; 3,940 municipal offices; 5,029 veterinarians; and 13,357 technical and<br />
administrative assistants and support personnel [9]. The LVUs consist of one or more municipalities<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 14
and implement animal health activities within the area they represent. The local units are<br />
administratively grouped into regional units (19 total in Santa Catarina). Epidemiologic and health<br />
data collected by the LVUs are consolidated and analyzed at the local level, used as appropriate, and<br />
then forwarded to regional, State, and national offices [4]. Geographic distribution of regional and<br />
local veterinary units in Santa Catarina is displayed in Figures 3 and 4, respectively, below.<br />

Number of resources<br />
There are 295 official veterinarians working in Santa Catarina. These professionals participate in the<br />
surveillance system supporting the official veterinary service, in activities to promote animal health,<br />
and in notification of animal disease suspicions, especially vesicular diseases [11].<br />
During the 2008 site visit, the site visit team visited the regional office in Chapeco, along with two<br />
LVUs located within this region: Xanxerê and Seara. The Chapeco regional office has jurisdiction<br />
over 44 municipalities divided into 18 LVUs. It includes 404,000 residents and covers 7,095 square<br />
kilometers. The livestock population consists of 1,164,000 commercial and 15,000 backyard pigs<br />
and 700,000 cattle. Forty-seven official veterinarians work within this region, most of whom are<br />
stationed at LVUs. Additional staffing within the region includes 22 clerks, 6 field assistants, and 74<br />
personnel stationed at sanitary barriers. Four and three veterinarians, respectively, operated out of<br />
the Xanxerê and Seara local offices [11].<br />
Representative State activities administered by LVU personnel include registering properties,<br />
collecting and tracking census data, monitoring vaccination and controlling vaccine distribution,<br />
animal and animal product movement control, reporting suspicious cases, monitoring and<br />
eradicating outbreaks, surveillance activities, monitoring local animal gathering events (such as fairs,<br />
expositions, and auctions), monitoring clinical investigations and sampling, and conducting local<br />
training and outreach [6, 10].<br />
Personnel who observe conditions consistent with <strong>FMD</strong> or swine diseases, including CSF, SVD, and<br />
ASF, must immediately notify Federal officials. The Federal, State and private sectors exchange<br />
information freely. Local and regional offices prepare weekly and monthly reports that are shared<br />
among the three sectors[6, 10]. Interaction among local, regional, State, and Federal authorities and<br />
private and international organizations is structured and effective.<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 17
Private coordination/contributions<br />
Veterinary control and infrastructure in <strong>Brazil</strong> depend on close interaction between Federal and State<br />
offices, but their functions are also supported strongly by producer groups. In fact, this interaction<br />
with producers is defined by regulation and considered by <strong>Brazil</strong>ian officials to be a significant<br />
factor in controlling <strong>FMD</strong>. The private sector is strongly committed to general animal health<br />
activities as well as disease eradication and traceability (identification) systems, and shows its<br />
support by substantial financial contributions [6, 7, 10].<br />
Professionals who work in the private sector are often invited to participate in lectures and technical<br />
meetings with representatives of the official veterinary service. Private sector veterinarians can<br />
register with MAPA and CIDASC to issue animal movement forms (Guia de Transito Animal, or<br />
GTAs) for the movement of pigs and poultry, as each official veterinarian works in a limited number<br />
of municipalities [4].<br />
During the 2008 site visit the team observed strong interactions between CIDASC veterinarians,<br />
production company (cooperative) veterinarians, and producers. The cooperative veterinarians<br />
trained the producers in basic animal health and production, biosecurity, and disease recognition and<br />
reporting requirements. The official veterinary services, in turn, trained the private veterinarians.<br />
On most swine farms, farmers have been trained to diagnose common causes of death, such as<br />
volvulus, by conducting their own necropsies, but appeared willing to contact their company<br />
veterinarian if they detected something unknown or suspicious of a viral infection. Company<br />
veterinarians are in turn required to contact the local CIDASC office upon suspicion of any<br />
notifiable diseases [11].<br />
Indemnity procedures<br />
<strong>Brazil</strong> law requires indemnity. The main indemnity procedures are based on Law No. 569, passed<br />
December 21, 1948, which establishes measures to safeguard public health or for the sanitary<br />
protection of animals. The Federal government pays indemnity for (1) animals sacrificed due to the<br />
presence of <strong>FMD</strong> or any other exotic disease, (2) all susceptible animals that have the disease, and<br />
(3) all susceptible animals that have a history of contact with affected animals. The Federal<br />
government provides money for payments; money also comes from private indemnity funds created<br />
and administered by producers. Federal funds come from the national treasury and complement<br />
indemnity funds administered by producers [12].<br />
Whenever sick animals must be destroyed to safeguard public health, or there is destruction of rural<br />
buildings or objects, the proprietor must receive financial compensation. Compensation is paid after<br />
the situation is assessed in accordance with regulations of MAPA and the State government.<br />
The producers’ private indemnity fund in various <strong>Brazil</strong>ian States comes from fees paid by<br />
producers and slaughter establishment officials for authorization to move and slaughter animals.<br />
Santa Catarina has public and private funds for compensation during disease emergencies. During<br />
the 2008 site visit, CIDASC reported a fund for animal health activities of 17,763,757 reales<br />
(approximately $11 million.). <strong>Brazil</strong>’s laws require that records of the entire indemnity process be<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 18
kept, with the documentation being available for auditing in the involved States (presentation<br />
CIDASC). Owners have been duly compensated in all animal sanitary emergency activities carried<br />
out in <strong>Brazil</strong> [11].<br />
Garbage control/swill feeding<br />
Swill feeding to swine is prohibited in all regions of <strong>Brazil</strong> by Decree No. 201, issued May 1998 [5].<br />
State laws in Santa Catarina also prohibit garbage feeding. Although Federal law allows some<br />
feeding with inactivation of waste, this practice is forbidden by Santa Catarina State law. Official<br />
veterinarians at the Seara local office reported that if they identified garbage feeding during a farm<br />
visit they would provide guidance and a verbal warning to stop it. Upon a second finding they<br />
would issue a fine; however, the officials reported that this has never been necessary[11].<br />
Conclusions:<br />
APHIS considers that MAPA has sufficient legal authority to carry out official disease control,<br />
eradication, and quarantine activities. MAPA has a system of official veterinarians and support staff<br />
in place for carrying out field programs and for import controls and animal quarantine. Review of<br />
veterinary infrastructure with MAPA and CIDASC officials demonstrated an infrastructure adequate<br />
for rapid detection of <strong>FMD</strong>, CSF, ASF, and SVD and for carrying out surveillance programs in<br />
Santa Catarina. The technical infrastructure is adequate, and officials use advanced technologies to<br />
conduct animal health programs.<br />
Santa Catarina’s LVU offices are adequately staffed. Assuming that the offices visited during the<br />
site visit are representative of LVUs throughout the State, the local contacts, coverage, and control<br />
mechanisms are strong. LVU functions observed in relatively high-risk regions demonstrated close<br />
contact with individual premises in the regions and strong local controls. LVU personnel appeared<br />
to be adequately trained in identifying the clinical signs of <strong>FMD</strong>, SVD, ASF, and CSF. In addition<br />
they have a close relationship with animal producers and private/company veterinarians in charge of<br />
cooperative farms. All parties are willing to report suspicious incidents to the next level. LVU<br />
personnel also regularly provide information on disease signs and reporting requirements to<br />
producers within their coverage area. It is expected that producers would suspect any of the diseases<br />
under evaluation if they were to see them.<br />
During our site visits to <strong>Brazil</strong> in 2002, 2003, 2006, and 2008, APHIS received overviews of the<br />
activities and structures of Federal, State and local authorities. APHIS reviewed premises<br />
registration, census information, vaccination records, and movement control documents. Our<br />
personnel visited farms to observe farming practices. Officials observed that the structure,<br />
effectiveness, and organization of the LVUs in Santa Catarina were adequate to perform official<br />
animal health functions [6, 11].<br />
With regard to indemnity procedures, APHIS concluded that sufficient funds are available to<br />
compensate owners for sacrificed animals. In addition, indemnity provisions can be extended to<br />
exposed and contact animals. Livestock producers and other industry groups contribute to and<br />
administer private compensation funds, which show the level of commitment and participation of the<br />
cattle industry in <strong>FMD</strong> program activities and of the swine industry to <strong>FMD</strong>, CSF, SVD, and ASF<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 19
program activities. Availability of indemnity provisions should encourage disease reporting and<br />
complement detection efforts carried out by official veterinary services.<br />
2. Disease status in the export region<br />
Gaining a thorough understanding of the history of <strong>FMD</strong>, CSF, ASF, and SVD in a region is<br />
essential to assessing its existing export risk. Assessment of risk includes a consideration of the<br />
effectiveness of control measures the region implements and revises as appropriate. Consequently,<br />
this section focuses on historical outbreaks and eradication efforts in Santa Catarina.<br />
<strong>FMD</strong><br />
<strong>FMD</strong> vaccination became mandatory in <strong>Brazil</strong> in 1965. The first systematic vaccinations were<br />
implemented in 1967 through a joint action of the Federal and State governments. In 1992, the<br />
policy and strategies against <strong>FMD</strong> were reviewed; as a result, the vaccinations were enforced<br />
regionally based upon livestock demographics. Stakeholders (producers, agricultural industry, retail,<br />
universities, etc.) were incorporated as a main element in all phases and activities in the National<br />
Program for Foot-and-Mouth Disease Eradication (PNEFA - Programa Nacional de Erradicação da<br />
Febre Aftosa). Consequently, in 1998, the OIE recognized the first <strong>FMD</strong>-free area where<br />
vaccination was practiced.<br />
The last <strong>FMD</strong> outbreak in Santa Catarina occurred in 1993. Santa Catarina achieved international<br />
recognition in 1998 as <strong>FMD</strong>-free with vaccination. In 2000, the year that vaccination ceased in Rio<br />
Grande do Sul, an <strong>FMD</strong> outbreak occurred in that State. No <strong>FMD</strong> was detected in Santa Catarina.<br />
The 2000 Rio Grande do Sul outbreak affected 22 premises. The disease was eliminated by<br />
stamping out (destruction of the affected animals). Officials suspected that the disease was linked to<br />
a Type O1 <strong>FMD</strong> outbreak in Argentina, which also occurred in 2000. Transit of infected cattle in<br />
the border region between Argentina, <strong>Brazil</strong>, and Uruguay was implicated as the pathway of<br />
introduction. At that time, vaccination against <strong>FMD</strong> remained suspended in Santa Catarina and Rio<br />
Grande do Sul. In 2007, OIE recognized Santa Catarina as an <strong>FMD</strong>-free zone where vaccination is<br />
not practiced (see Figure 5).<br />

CSF<br />
No outbreaks of CSF have occurred in Santa Catarina since 1990 [13]. In addition, there have been<br />
no outbreaks in the CSF-free portion of <strong>Brazil</strong>, which comprises the 12 southernmost <strong>Brazil</strong>ian<br />
States, since 1998 (see Figure 6). The CSF-free zone of <strong>Brazil</strong> was declared in January 2001<br />
according to Normative Instruction SDA 01/2001. It consists of almost half of the <strong>Brazil</strong>ian territory<br />
and 80 percent of the national swine population [9].<br />
Figure 6: CSF-Free Zone in <strong>Brazil</strong>, 2008 [9]<br />
Infected Zone<br />

APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 21
Fifteen outbreaks have been detected since declaration of the free zone in <strong>Brazil</strong> in 2001, all of<br />
which occurred in the non-free zone. Most occurred in the State of Ceará; one outbreak occurred in<br />
Paraíba in 2006 and one in Maranhão in 2008 [9, 14].<br />
ASF<br />
No outbreaks of ASF have occurred in <strong>Brazil</strong> since 1981. As of 1984 [15], all of <strong>Brazil</strong> was<br />
declared to be ASF-free and continues to be regarded as such [14].<br />
SVD<br />
SVD has never occurred in <strong>Brazil</strong> [14].<br />
Conclusions:<br />
Santa Catarina’s last <strong>FMD</strong> outbreak occurred in 1993. No outbreaks of ASF have occurred in Santa<br />
Catarina since 1981 and no outbreaks of CSF have occurred in Santa Catarina since 1990. SVD has<br />
never occurred in <strong>Brazil</strong>. There is no evidence of any <strong>FMD</strong>, CSF, SVD, or ASF infections or<br />
outbreaks in Santa Catarina.<br />
3. Disease status of adjacent regions<br />
This section describes the disease status in other areas of <strong>Brazil</strong> with respect to <strong>FMD</strong>, CSF, ASF, and<br />
SVD, and in Argentina, which borders Santa Catarina (Figure 7).<br />
Figure 7: <strong>Brazil</strong> and neighboring countries<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 22
<strong>FMD</strong><br />
<strong>Brazil</strong> currently has several different <strong>FMD</strong> zones. Santa Catarina is the only zone designated by the<br />
OIE as free of <strong>FMD</strong> without vaccination. At the time of this analysis, the area recognized by the<br />
OIE as free of <strong>FMD</strong> with vaccination contains 16 States, mostly located in the southern and central<br />
portion of <strong>Brazil</strong> (OIE reference). Santa Catarina is surrounded by the States of Rio Grande Do Sul<br />
and Paraná, both recognized by the OIE as free of <strong>FMD</strong> with vaccination. Outbreaks of <strong>FMD</strong> have<br />
occurred in Rio Grande Do Sul (2000/2001) and Paraná and Mato Grosso do Sul in 2005 and 2006.<br />
Rio Grande do Sul<br />
In 2000, the year that vaccination ceased in Rio Grande do Sul, an <strong>FMD</strong> outbreak occurred in that<br />
State. <strong>FMD</strong> was not detected in Santa Catarina. The Rio Grande do Sul outbreak affected 22<br />
premises in four neighboring municipalities in the northwestern region of the State. The disease was<br />
eliminated by stamping out. The eradication program involved the destruction of 11,017 animals<br />
(8,185 bovine, 2,106 swine, 722 ovine, and 4 caprine species). In addition, officials imposed strict<br />
movement controls and biosecurity measures [6, 7, 12, 16]. The disease was linked to a Type O1<br />
<strong>FMD</strong> outbreak in Argentina that occurred in 2000. Transit of infected cattle in the border region<br />
between Argentina, <strong>Brazil</strong>, and Uruguay was implicated as the pathway of introduction. At that<br />
time, vaccination against <strong>FMD</strong> remained suspended in Rio Grande do Sul [16, 17].<br />
In 2001, another outbreak occurred in Rio Grande do Sul affecting 30 premises in six different<br />
municipalities. In this outbreak, in addition to implementing a stamping out program, officials<br />
carried out emergency vaccination for all cattle in the State. A total of 2,348 farms were quarantined<br />
and 32,408 animals were slaughtered. No direct epidemiological relationships between the six<br />
affected municipalities were identified. Investigation results suggested that the six outbreaks<br />
resulted from independent re-introductions, all coming from Uruguay. Direct epidemiological<br />
relationships were established between the owner of an affected herd in one municipality and<br />
producers in Uruguay. The observation that the first occurrence of disease was farther away from<br />
the border than subsequent occurrences was significant because the owner of the affected herd had<br />
been in Uruguay a few days before the outbreak erupted in his herd.<br />
No direct relationship was identified between the outbreaks in the six municipalities and the<br />
outbreaks in Argentina since the virus in Argentina was type O and the virus in Uruguay was<br />
classified as type A [6]. At that time, vaccination against <strong>FMD</strong> was reinstated throughout Rio<br />
Grande do Sul [16, 17].<br />
Paraná<br />
On October 21, 2005, <strong>Brazil</strong>ian authorities detected <strong>FMD</strong> in the State of Paraná. The outbreak was<br />
immediately reported to the OIE. As a result, the affected properties, as well as those located within<br />
a 10-km radius, were immediately quarantined and interdicted. Paraná reported a total of 11<br />
outbreaks (two outbreaks in Maringá, one in Grandes Rios, four in Loanda and two in Amaporã).<br />
Epidemiological investigation revealed that the disease entered Paraná because of the movement of<br />
87 heifers from Mato Grosso do Sul on September 27, 2005. These animals originated from a<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 23
property that was later identified as (1) having had <strong>FMD</strong> cases, and (2) being adjacent to two<br />
properties with <strong>FMD</strong> cases. The animals involved remained for 8 days in the municipality of Bela<br />
Vista do Paraiso in Paraná, and subsequently sold at auction in the municipality of Londrina.<br />
Clinical and seroepidemiological investigations identified 11 properties with suspected <strong>FMD</strong>.<br />
By April, 2006 a total of 6,781 cattle had been destroyed to fight the outbreak. Officials made<br />
several attempts to isolate and identify the virus; however, due to several factors (such as samples<br />
taken not being suitable for virus isolation), the laboratory staff could not identify the presence of the<br />
<strong>FMD</strong> virus. Nevertheless, based on the clinical signs and epidemiological links to outbreaks in Mato<br />
Grosso do Sul, the episodes were confirmed as <strong>FMD</strong>, and officials declared a state of sanitary<br />
emergency.<br />
Argentina<br />
Argentina borders the <strong>Brazil</strong>ian States of Rio Grande do Sul, Santa Catarina, and Paraná. In July<br />
2000, officials recorded an outbreak caused by virus type O. Additional premises were infected with<br />
virus type O through December 2000 in multiple provinces, including Corrientes and Misiones.<br />
Detection of separate premises affected with virus type A between August and December 2000<br />
compounded the situation. Subsequently, multiple outbreaks of virus type A occurred between<br />
March 2001 and January 2002 throughout Argentina, including 70 outbreaks in Corrientes near the<br />
border with the Paraná River. In addition, in September 2003, a single outbreak of virus type O<br />
occurred in the northern province of Salta. This outbreak was limited to swine in a single premises<br />
and Argentina declared eradication in early October.<br />
In 2006, Argentina reported an outbreak of virus type O in San Luis del Palmar (Corrientes) near the<br />
border with Paraguay. This outbreak was quickly contained and eliminated. Molecular<br />
characterization of the virus revealed that the strain was indigenous to the region and shares common<br />
similarities with the isolates responsible for the type O outbreaks in South America between 2000<br />
and 2005 [18]. Specifically, studies showed that the virus presented a high degree of homology (96<br />
percent) with virus types isolated in Pozo Hondo (Paraguay) in 2003 and in Tarija (Bolivia) in 2000,<br />
and with 92 percent homology with virus isolated in Mato Grosso do Sul (<strong>Brazil</strong>) in 2005.<br />
<strong>Brazil</strong> appears to have successfully prevented the introduction of <strong>FMD</strong> from Argentina during some<br />
but not all outbreaks in that country.<br />
Regional approach to <strong>FMD</strong> eradication in South America<br />
A plan to eradicate <strong>FMD</strong> in all of South America by 2009 – the Plano Hemisferico de Eradicacao da<br />
Febre Aftosa, or PHEFA – was created in the mid-1980s. Under this plan, a regional partnership<br />
agreement involving <strong>Brazil</strong>, Argentina, Uruguay, Paraguay, Chile, and Bolivia (the Convention da<br />
Barcia do Rio do Prata) was implemented in 1997. This agreement aims to integrate the various<br />
national and regional <strong>FMD</strong> programs and to coordinate sanitary measures for <strong>FMD</strong> control and<br />
eradication, particularly in the border regions [16, 17].<br />
As part of the partnership agreement, the veterinary services in the border regions are jointly<br />
preparing maps that demonstrate the commercial flow of susceptible animals to pinpoint areas of<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 24
higher risk. In addition, the local veterinary services of the involved countries meet periodically to<br />
discuss available information and conduct joint activities, thereby improving horizontal relationships<br />
and disease reporting at the local level.<br />
CSF<br />
As previously described, <strong>Brazil</strong> was declared a CSF-free zone in 2001. Santa Catarina is located<br />
within this CSF-free zone, as are both of its adjoining <strong>Brazil</strong>ian States. No outbreaks of CSF have<br />
occurred in Santa Catarina since 1990 [13]. There have been no CSF cases detected in the CSF-free<br />
portion of <strong>Brazil</strong> since it was declared. Although CSF outbreaks have occurred in <strong>Brazil</strong> since this<br />
time, the outbreaks have been limited to States in the northeastern portion of the country, far from<br />
Santa Catarina. Movement controls are in place at the border between the CSF-infected and free<br />
zones of <strong>Brazil</strong> and have prevented spread of the disease into the free zone [9].<br />
The last reported case of CSF in Argentina occurred in 1999 [14].<br />
ASF<br />
ASF was first reported in <strong>Brazil</strong> in 1978 in the State of Rio de Janeiro. It is believed that the disease<br />
entered via infected food leftovers from an incoming passenger flight from Portugal, which was<br />
experiencing outbreaks of ASF at the time. Within <strong>Brazil</strong>, the outbreaks were concentrated in farms<br />
that produced pigs for their own consumption. These farms were located on the outskirts of Rio de<br />
Janiero and had access to food waste [13]. The outbreak was contained through stamping out and<br />
increasing biosecurity to prevent exposure to infective materials and wild boar. <strong>Brazil</strong> has had no<br />
further outbreaks of ASF since 1981 [14] and has been declared officially free of ASF since 1984<br />
[15].<br />
ASF has never been reported in Argentina [14].<br />
SVD<br />
SVD has never been reported in Argentina [14].<br />
Conclusions:<br />
There is no evidence that <strong>FMD</strong> has been transported from surrounding countries or regions of <strong>Brazil</strong><br />
into Santa Catarina. CSF has not occurred within Santa Catarina since 1990. Although CSF has<br />
been detected in recent years in the CSF-infected zone of <strong>Brazil</strong>, movement controls have prevented<br />
introduction of the disease into the free area. CSF does not appear to be circulating within Argentina<br />
at this time; therefore, it is not likely that transmission of disease would occur from this source. ASF<br />
has not occurred in <strong>Brazil</strong> for nearly 30 years, and it has never been reported in Argentina.<br />
Therefore, it is highly unlikely that the virus exists in areas neighboring Santa Catarina or that these<br />
areas pose a risk for disease transmission. SVD has never been reported to occur anywhere within<br />
<strong>Brazil</strong> or in Argentina.<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 25
4. Extent of an active disease control program<br />
In this section we describe the disease control programs that led to the eradication of <strong>FMD</strong>, CSF,<br />
ASF, and SVD in Santa Catarina, and review MAPA and CIDASC program activities.<br />
The <strong>Brazil</strong>ian <strong>FMD</strong> program strategy consists of defining a region based on the livestock circuit or<br />
ecosystem. Eradication efforts are coordinated by region. The program relies heavily on community<br />
involvement and joint activities with stakeholder groups interested in animal health and production.<br />
<strong>Brazil</strong> has formed local groups that work under the coordination of the States’ regional and central<br />
offices. One of the main objectives of the program is to shift decision-making to the LVUs, which<br />
take sanitary actions and generate technical information.<br />
The DDA coordinates and supervises all aspects of the <strong>FMD</strong> program. The DDA:<br />
Develops strategies to combat the disease.<br />
Develops program rules.<br />
Controls interstate and international movement of animals, products, and byproducts.<br />
Registers, tests, and controls specific vaccines.<br />
Conducts laboratory tests for disease diagnosis and virus isolation.<br />
Conducts disease surveillance and information systems at national and international levels.<br />
Audits State veterinary services.<br />
Conducts sanitary education and training of program personnel.<br />
Conducts veterinary inspection of animals, animal products, and byproducts at origin and<br />
after importation.<br />
Provides financial support through cooperative agreements with the States.<br />
The States implement program strategies. The States’ secretariats:<br />
Execute programs at the field level.<br />
Maintain an updated rural holdings register.<br />
Promote and monitor the <strong>FMD</strong> vaccination program for cattle and buffaloes.<br />
Supervise vaccinations in risky areas or holdings.<br />
Control intra- and interstate movement of animals and animal products (the interstate control<br />
is conducted in partnership with the Federal government).<br />
Help Federal authorities during outbreaks of the disease and investigation of suspected<br />
vesicular disease.<br />
Provide sanitary education,<br />
Organize community participation in the programs.<br />
Develop animal disease surveillance and information systems.<br />
Inspect livestock events such as fairs, exhibitions, auctions, and public sales.<br />
Inspect animals and their products and byproducts before movement.<br />
Train program personnel.<br />
The participation of the private sector in the national context is through CONASAN and occurs at all<br />
levels of administration (national, State, and municipal). The private sector supports the <strong>FMD</strong><br />
program by providing financial resources and participating in the program’s planning, financing,<br />
implementation, and evaluation of the technical and managerial actions. According to <strong>Brazil</strong>ian<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 26
officials, the private sector’s participation has also strengthened official structures and improved<br />
sanitary actions, mainly within the local units of the surveillance system.<br />
The <strong>Brazil</strong>ian Government has promoted and guaranteed the involvement of various groups of<br />
CONASAN into a plan called the National Program for Foot-and-Mouth Disease Eradication, or<br />
PNEFA. These groups are composed of people interested or involved in livestock production or<br />
health, such as rural producers, livestock and livestock product industry personnel, trade agents,<br />
private veterinarians, and members and officers of farmers’ unions, cooperatives, universities, and<br />
town halls. The objective of these alliances is to bring greater awareness, a wider scope,<br />
transparency, and credibility to the program. The Federal Government coordinates the<br />
implementation of the national plan.<br />
Eradication of <strong>FMD</strong> in Santa Catarina followed the basic strategies implemented by PNEFA and are<br />
summarized here:<br />
Strengthening and maintaining the animal health system, including hiring personnel for the<br />
official veterinary service through public agreements.<br />
Enacting and enforcing compliance with animal health laws.<br />
Registering rural holdings, herds, and all other establishments linked to the livestock<br />
production system.<br />
In its first phase, periodic mass vaccination of bovine animals and buffaloes which can be<br />
suspended and followed by actions to strengthen the primary surveillance system.<br />
Working on vesicular disease suspicions and implementing a stamping-out policy if officials<br />
confirm <strong>FMD</strong>.<br />
Control and surveillance of animal movement and prohibiting the entry of at-risk animals and<br />
animal products.<br />
Strengthening community participation.<br />
Auditing and supervising premises as needed.<br />
Main activities of the <strong>FMD</strong> and other swine notifiable disease program<br />
Disease surveillance<br />
<strong>Brazil</strong>’s animal health service has a surveillance system that covers the entire country. The LVUs<br />
collect the necessary data and make decisions based on the data. Many official and private sources<br />
supply the system’s information. In Santa Catarina, the field units collect and process surveillance<br />
data and forward the information to the regional offices. Santa Catarina’s central unit and a national<br />
unit represented by DDA and the MAPA SDA are located in Brasilia.<br />
The DDA official collects data from the State level and forwards the information to the OIE and<br />
other parties such as the South American Commission for the Fight against <strong>FMD</strong>. Reports are sent:<br />
Weekly for disease notifications.<br />
Monthly for confirmed cases of animal diseases.<br />
Biannually for the results of each phase of vaccination against <strong>FMD</strong> for each Federal unit.<br />
Annually for full reports of epidemiological and sanitary information.<br />
Notification and investigation of suspected cases<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 27
All official service field staff, community participants, and private sector veterinarians are trained<br />
and required to look for signs of notifiable diseases. If any of the listed diseases, including <strong>FMD</strong>,<br />
CSF, ASF, or SVD is suspected, the disease must be immediately reported to the local unit or to an<br />
authority that would notify the local unit.<br />
Response to a suspected outbreak begins within 12 hours from the time the unit receives notification.<br />
All actions are carried out as if the herd is infected until proven otherwise. The suspect holding is<br />
immediately quarantined, movement of animals is prohibited, and samples are collected and sent to a<br />
laboratory to confirm the diagnosis.<br />
Field inspections<br />
LVU personnel carry out special visits to certain herds classified as “risky” by the official service.<br />
<strong>Risk</strong>y herds are those owned by rural landless herd owners and Indian tribes, herds in areas densely<br />
populated with backyard and street cattle, or herds that have previously been affected by one of the<br />
diseases under evaluation. In addition, official veterinarians inspect animals prior to movement into<br />
Santa Catarina.<br />
Surveillance at abattoirs and meat packing plants<br />
Animals are individually inspected by personnel from the official service for signs of vesicular<br />
disease before slaughtering. Other body parts, including the tongue and feet, are examined during<br />
postmortem inspection.<br />
Surveillance at animal gathering places<br />
All animals entering fairs, auctions, or exhibitions are clinically inspected by official veterinarians.<br />
Laboratory diagnosis<br />
There are three laboratories for diagnosing <strong>FMD</strong>. These are located in Recife (Pernambuco State),<br />
Para (Belen State), and Pedro Leopoldo (Minas Gerais State). MAPA supervises these laboratories.<br />
The Pan-American Foot-and-Mouth Disease Center (PANAFTOSA), located in Rio de Janeiro, is<br />
the reference laboratory for <strong>FMD</strong> in <strong>Brazil</strong> and neighboring countries. The Recife laboratory<br />
performs routine serology for CSF, and for SVD and ASF if necessary.<br />
Serological monitoring<br />
Serologic studies follow OIE guidelines. (See section 9.)<br />
Regarding reportable swine diseases, current strategies under MAPA’s disease prevention and<br />
control programs include:<br />
Permanent sanitary surveillance.<br />
Mandatory and immediate notification of events or suspicion of occurrence of CSF or other<br />
swine diseases.<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 28
Immediate assistance to States for control and eradication of outbreaks.<br />
Control of the transit of swine, their products and byproducts, and genetic material.<br />
Control of pathological and biological products that are possible vectors of disease.<br />
Control of places where swine concentrate.<br />
Disinfection of vehicles, equipment, and environments.<br />
Destruction of potentially infected materials.<br />
Control of stamping-out policies.<br />
Control and prohibition on the use of vaccines.<br />
None of the diseases under evaluation have been found in Santa Catarina for more than 8 years.<br />
Activities designed to detect and prevent introduction of any of these diseases and quickly eradicate<br />
them are all in place and are described in subsequent sections of this document.<br />
Conclusions:<br />
APHIS considers that Santa Catarina has a control program and a national plan sufficient to respond<br />
quickly to any emergencies related to the diseases under evaluation. Santa Catarina has a structured<br />
system of notification and official involvement to investigate all reports of suspected vesicular<br />
disease. In addition, Santa Catarina maintains a surveillance program at the field level on farms, in<br />
slaughterhouses, and at animal gathering locations.<br />
The community takes an active part in program activities, which has played an integral role in the<br />
motivation and strengthening of the program.<br />
5. Vaccination status of the region<br />
Santa Catarina does not vaccinate against <strong>FMD</strong>. <strong>FMD</strong> vaccination was last applied in May 2000.<br />
<strong>Brazil</strong> prohibited CSF vaccination in 1998.<br />
MAPA may approve emergency CSF or <strong>FMD</strong> vaccinations if necessary. The vaccinations must be<br />
conducted under the strict control of the official veterinary services [4]. Vaccine has been<br />
administered as part of outbreak control measures in the CSF-infected zone, although this has not<br />
occurred since 2003 (OIE). Vaccine has not been used anywhere within the CSF-free zone since it<br />
was prohibited in 1998 [3].<br />
There are currently no available vaccines for either SVD or ASF.<br />
Conclusions:<br />
Santa Catarina does not vaccinate for any of the diseases under evaluation. In the absence of<br />
vaccination, it is likely that clinical signs resulting from an incursion of disease would be quickly<br />
identified.<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 29
6. Separation from adjacent regions of higher risk<br />
Geographic barriers, such as mountains or expanses of water, impede the natural and humanmediated<br />
movements of animals and animal products. In this section we highlight the geographical<br />
and other barriers that limit introduction of diseases from other <strong>Brazil</strong>ian States into Santa Catarina.<br />
Santa Catarina is in the southern region of <strong>Brazil</strong>, between parallels 25º 56 and 29º 23 S and<br />
meridians 48º 20 and 53º 51 W. The State has an area of 95,346 km 2 , representing about 1 percent<br />
of <strong>Brazil</strong>ian territory. Santa Catarina has two large regions separated by mountains: The coastal<br />
area, also referred to as the eastern area, which extends for approximately 400 km along the Atlantic<br />
Ocean; and the plateau area (or western area), the remaining 66 percent of the State’s territory. The<br />
western area is where the greatest livestock production occurs (See Figure 2).<br />
Santa Catarina is bounded to the east by the Atlantic Ocean, and otherwise borders the States of<br />
Paraná and Rio Grande do Sul and the Argentinian Province of Misiones. At the northern border of<br />
Santa Catarina, with Paraná, the border is approximately 860 km long, 54 percent of which is rivers.<br />
The remainder is formed by the Serra do Mar mountain ridge at the extreme northeast of the State.<br />
The south border, with Rio Grande do Sul, is approximately 1,170 km long, 65 percent (750 km) of<br />
which is formed by permanent rivers. The western border, with the Province of Misiones,<br />
Argentina, is 237 km long, 86 percent of which runs along the Rio Peperi-Guaçú. In Misiones, the<br />
border area is formed mainly by protected natural areas, among which is the Yaboti Biosphere<br />
Reserve.<br />
In addition to the geographical characteristics that control entry of products at risk for <strong>FMD</strong> into<br />
Santa Catarina, the protection system includes 67 fixed inspection posts, strategically located at the<br />
entry points. These inspection stations employ 429 professionals from the official veterinary<br />
service, who work in shifts that provide uninterrupted operation of the posts. Inspection station staff<br />
members are coordinated by an official veterinarian, and have police support. The inspection<br />
stations are described in further detail in Section 7 of this document.<br />
In addition, movement controls are in place between Santa Catarina (which is considered free of<br />
<strong>FMD</strong> without vaccination) and areas of <strong>Brazil</strong> affected with <strong>FMD</strong> or where vaccination against the<br />
disease is practiced. Similarly, there are movement controls between the CSF-free zone and the<br />
CSF-infected zone in the northern portion of <strong>Brazil</strong> [3, 4].<br />
Conclusions:<br />
Although some natural barriers to animal movement into Santa Catarina from surrounding areas<br />
exist, most of the controls of animal movement and their products are administrative. These two<br />
factors combined (geographical and administrative separation) have prevented the introduction of<br />
the diseases under evaluation into Santa Catarina. In addition, the lack of recent disease history for<br />
any of the diseases under evaluation in the adjacent areas further reduces the likelihood of their<br />
introduction into Santa Catarina.<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 30
7. Movement control, biosecurity, and the extent to which the movement of animals and<br />
animal products is controlled from regions of higher risk, and the level of biosecurity<br />
regarding such movements<br />
Border controls, including inspections at ports of entry and other surveillance practices, enable a<br />
country to monitor the movement of people, animals, and goods into the country or a particular<br />
region. Illegal movements of susceptible commodities or people and equipment can spread disease.<br />
A thorough understanding of animal movement controls helps assess the likelihood of disease<br />
introduction. Further, biosecurity measures are critical to minimize the spread of disease should an<br />
outbreak occur. In this section we review Santa Catarina’s border control capabilities for monitoring<br />
and controlling the movement of species and products that could carry the diseases under evaluation<br />
into the State.<br />
Among general animal health measures carried out by the official veterinary service in order to<br />
protect the animal health status of Santa Catarina, control at the entry points into the State is the<br />
primary prevention mechanism.<br />
Both international and domestic movement of animals and their products and byproducts are<br />
regulated by federal rules. MAPA is directly responsible for the control of permanent inspection<br />
stations on the border with Argentina, three ports and the international airport in Florianopolis, the<br />
State capital, through its International Plant and Animal Surveillance (Vigilância Agropecuária<br />
Internacional). Santa Catarina controls other inspection stations through CIDASC [4].<br />
Animals must be accompanied by a Zoosanitary Certificate signed by an official veterinarian from<br />
the exporting country, pursuant to the model in Normative Instruction SDA 31/2002. Controls for<br />
international transport and trade are defined by Normative Instruction SDA 47/2001, which bans the<br />
import of animals and products at risk of <strong>FMD</strong> from countries where the disease has occurred.<br />
Normative Instruction SDA 31/2002 and Normative Instruction SDA 54/2002 include information<br />
on the extent of control and biosecurity measures on imports from higher risk areas for CSF. The<br />
movement from the non-free zone into <strong>Brazil</strong>’s free zone of animals or other products capable of<br />
introducing CSF is regulated by Normative Instruction SDA 01/2001. The requirements for entry of<br />
animals, products, and byproducts at risk for <strong>FMD</strong> into Santa Catarina are contained in Normative<br />
Instruction SDA 05/2003 [3, 4].<br />
All animals and products (plus plant products) must enter and leave Santa Catarina via one of the 67<br />
fixed inspection stations [4].<br />
Domestic movement controls and animal identification<br />
<strong>Brazil</strong> has stringent movement controls. MAPA requires that all cattle owners identify their animals<br />
with a unique brand. Sheep and swine are identified by an individual brand or notch in the ear.<br />
Each LVU keeps a registry of identification systems and a complete registry of the livestock<br />
holdings in the region with animal populations listed by age group and sex. The registry must be<br />
updated at least twice a year, and whenever animals are moved (farmers must notify the LVU of<br />
changes to the animal inventory due to birth, death, or movement off premises and must do so within<br />
30 days [7].<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 31
The <strong>Brazil</strong>ian System for Identification and Origin Certification for Bovines and Buffaloes<br />
(SISBOV- Sistema Brasileiro de Identifação e Certificação de Origem Bovina e Bubalina) is<br />
currently being used in Santa Catarina. Within Santa Catarina, CIDASC has implemented a program<br />
for the individual identification of the State’s entire herd. This identification is mandatory, with ear<br />
tags issued by the State government, as per State Ordinance n. 44, issued December 18, 2006 [4].<br />
The LVU must issue an animal movement permit (GTA) before any animal can be moved [6].<br />
Those seeking a GTA must meet certain requirements, such as: balance of animals for the specific<br />
age group and sex; vaccination against the diseases listed by the local veterinary service; obtaining<br />
sanitary certificates, when necessary; and meeting the necessary sanitary condition or status at the<br />
origin and at the destination. A copy of the GTA is sent to the destination. In addition, the LVU<br />
staff must verify that the vehicle transporting the animals has been cleaned and disinfected as<br />
required by law [4, 7].<br />
The GTA must include a list of the bar codes of all animals in the shipment. If animals are going to<br />
slaughter, the slaughter plant must make sure that all of the numbers and animals are accounted for<br />
and that the information is recorded in a controlled database [11].<br />
Pigs are sent by lot to slaughter. Each farmer has a specific farm number which is applied by back<br />
tag when the animal is moved to slaughter. Piglets also receive ear notches. If necessary, a lot of<br />
animals can be traced back to the piglet level through the GTA (the lots stay together throughout<br />
their lifetime). Some slaughterhouses will slaughter cull animals (i.e., not shipped by lot); however,<br />
these animals are slaughtered last each day and if any problems (such as signs of disease) are noted<br />
the plant will stop the line and disinfect the premises and staff clothing [11].<br />
The official veterinary service controls animal movement within the country. At the request of the<br />
potential purchaser, the official service of the destination State analyzes the risk rating of the origin<br />
State [5]. The main factors considered in the risk rating are:<br />
The time passed since the last outbreak<br />
The presence or absence of viral activity<br />
The extent of vaccine coverage<br />
Control and inspection of incoming animals and products<br />
The disease status of adjacent areas<br />
The infrastructure of the official services<br />
The level of surveillance<br />
The degree of community participation [19]<br />
If the risk rating is acceptable, and the destination and origination premises are suitable for<br />
quarantine purposes, the movement process begins [16]. Animals are isolated at the origin property<br />
for at least 30 days, during which time they are serologically tested for <strong>FMD</strong>. Once moved, the<br />
animals are isolated at the destination property for another 14 days and re-tested. If a single animal<br />
tests positive for <strong>FMD</strong>, the entire group is denied entry (except for animals moving directly to<br />
slaughter) and the official service conducts an epidemiological investigation [19].<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 32
In 2005, Santa Catarina’s official veterinary service issued 272,000 movement permits, which<br />
included the movement of 14 million <strong>FMD</strong>-susceptible animals. Ninety-two percent of the permits<br />
were issued for intrastate movement and the other 8 percent permitted movement to other States,<br />
especially neighboring ones. Ninety-six percent of the animals moved were swine. Fifty-three<br />
percent of those were transported to slaughter. Cattle movements accounted for 3.7 percent of all<br />
movements, and small ruminants accounted for less than 1 percent. In the period from January to<br />
October 2006, a total of 258,000 GTAs were issued allowing the movement of 11 million <strong>FMD</strong>susceptible<br />
animals. Similar percentages were reported in 2005, with swine representing 94 percent<br />
of all animals moved [4].<br />
Table 3 shows the movement of <strong>FMD</strong>-susceptible and nonvaccinated animals into Santa Catarina<br />
from other <strong>Brazil</strong>ian States recognized by MAPA as <strong>FMD</strong> free or where vaccination is practiced.<br />
All movements are recorded by GTAs and the animals were inspected at the point of entry. The<br />
entry is regulated by the Normative Instruction SDA 05/2003[4].<br />
In specific cases of swine, in 2005 and 2006, only animals for reproductive purposes from Certified<br />
Swine Breeding Farms (Granjas de Reprodutores Suideos Certificadas – GRSC) were allowed into<br />
Santa Catarina. These farms have a high level of biosecurity, having been subject to certification by<br />
the official veterinary service every six months. The farms keep their own permanent veterinary<br />
assistance and only swine from other GRSCs can enter the premises. In 2006, swine that entered<br />
Santa Catarina came from 36 GRSCs. Animals from Mato Grosso do Sul and Parana, where <strong>FMD</strong><br />
outbreaks were reported, came from farms not located in the municipalities where the disease<br />
occurred.<br />
Santa Catarina is a large producer of swine. Of all the animals slaughtered in the State, only 2<br />
percent came from other States [4].<br />

Santa Catarina is a large producer of swine. Of all the animals slaughtered in the State, only 2<br />
percent came from other States. The movement of swine during 2007 in Santa Catarina according to<br />
purpose is described in Table 4 below.<br />

The requirements for entry of animals, animal products and byproducts at risk for <strong>FMD</strong> into Santa<br />
Catarina are contained in Normative Instruction SDA 05/2003. Any animals, animal products and<br />
byproducts, veterinary products, material or substances that might transmit the <strong>FMD</strong> virus cannot<br />
enter the State. However, <strong>FMD</strong>-susceptible animals may enter Santa Catarina if the importer seeks<br />
prior authorization from MAPA. This request for authorization must include specific information on<br />
the animals’ place of origin, route and destination, sanitary tests, a place of destination for isolation,<br />
and a description of the animals. The authorization must include the date and identification of the<br />
issuer. All animals must undergo clinical inspection and quarantine at both their points of origin and<br />
their destination [4].<br />
No bovines or other animals vaccinated against <strong>FMD</strong> are allowed to enter Santa Catarina. However,<br />
certain animals and animal products originating from <strong>FMD</strong>-free zones in <strong>Brazil</strong> where vaccination is<br />
practiced may enter Santa Catarina with certain provisions. Sheep, goats, and pigs destined for<br />
immediate slaughter may enter if they have not been vaccinated and were born in States MAPA<br />
considers to be <strong>FMD</strong>-free with vaccination. They must be transported in vehicles that have been<br />
sealed by the official veterinary service of the State of origin. Sheep, goats, and pigs may also enter<br />
for stocking, fattening, breeding, or exhibition if they receive prior authorization from the official<br />
veterinary services of Santa Catarina and if they are subjected to a 30-day pretransport quarantine<br />
approved by and under the supervision of the official veterinary services, have tested negative for<br />
<strong>FMD</strong>, and are transported in sealed vehicles [4].<br />
Maturated boneless beef may enter if it is obtained from bovines that have remained in the <strong>FMD</strong>-free<br />
(with vaccination) State for the 2 years immediately before slaughter (or since birth in the case of<br />
animals less than 2 years old), were slaughtered in slaughterhouses under Federal inspection, did not<br />
show signs of <strong>FMD</strong> at the time of being transported, and displayed no <strong>FMD</strong> lesions on antemortem<br />
or postmortem inspection. Additional animal products are permitted from <strong>FMD</strong>-free (with<br />
vaccination) States as long as they are processed in a manner that eliminates <strong>FMD</strong> infectivity [4].<br />
Certain products are also permitted from States located in a buffer zone or infected zone for <strong>FMD</strong><br />
with medium or low-risk <strong>FMD</strong> classification. These include maturated boneless beef as described<br />
above sent directly to inspected establishments within Santa Catarina where it is processed for<br />
internal consumption, or fresh pork that has been treated to inactivate the <strong>FMD</strong> virus. Other<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 34
products, such as offal for human consumption that has been heat-treated to inactivate the <strong>FMD</strong><br />
virus, raw hides and skins salted with sea salt containing 2 percent sodium carbonate, tanned hides<br />
and skins, hoofs, horns, hairs, and manes, processed animal feed, tallow, and beef and dairy products<br />
and byproducts that have been submitted to physical and chemical treatment capable of inactivating<br />
the <strong>FMD</strong> virus, are also permitted [4].<br />
Swine from the non-CSF-free area of <strong>Brazil</strong> may not enter the CSF-free zone (which includes Santa<br />
Catarina) with certain exceptions. Pigs from non-CSF free areas may enter for immediate slaughter<br />
only, with prior authorization by MAPA and provisions that the pigs have lived on the farm of origin<br />
since birth or are quarantined at the farm of origin with negative serological tests for CSF [9].<br />
International movement controls<br />
International transport and trade controls are defined by Normative Instruction SDA 47/2001. SDA<br />
47 bans the import of animals and products at risk of <strong>FMD</strong> from countries where the disease has<br />
occurred[4]. Information on the extent of control and biosecurity measures on imports from higher<br />
risk areas for CSF are included in Normative Instruction SDA 31/2002 and Normative Instruction<br />
SDA 54/2002 and are listed in Annex 1. The movement of animals or other products capable of<br />
introducing CSF into the free zone of <strong>Brazil</strong> from the non-free area is regulated by Normative<br />
Instruction SDA 01/2001[3].<br />
The list of countries from which <strong>FMD</strong>-susceptible animals and their products and byproducts may<br />
enter is based on OIE recognition as updated by DSA (the animal health directors). Unauthorized<br />
countries may import some products if the producers meet specific requirements that ensure sanitary<br />
safety. These requirements are similar to those outlined above for products entering Santa Catarina<br />
from other <strong>Brazil</strong>ian States [4].<br />
Swine destined for import must originate from a country or region considered free from ASF, SVD,<br />
CSF, and other diseases, according to the standards set by the OIE as recognized by MAPA. In<br />
addition, the animals must be quarantined at the point of origin and tested (with negative results) for<br />
brucellosis, TB, CSF, Aujesky’s disease, porcine reproductive and respiratory syndrome (PRRS),<br />
transmissible gastroenteritis, enterovirus encephalomyelitis, and leptospirosis. The condition of the<br />
country, zone, or establishment as free from a given disease waives the need to test for the disease<br />
during quarantine at the point of origin. In addition, a second 14-day quarantine must be conducted<br />
upon entry into <strong>Brazil</strong> under the supervision of the official veterinary service. Animals are<br />
quarantined in establishments approved by MAPA and which employ a veterinarian to serve as the<br />
Technical Official in Charge [3].<br />
Individual identification is required for imported dairy and breeding animals. For slaughter animals,<br />
only information on the number, sex, and age of the animals is required, and they must be<br />
transported in a sealed vehicle. These animals must go to a federally inspected (SIF) plant and can<br />
only be used for the internal market because they have not been in the country for more than 90<br />
days. If an animal arrives at the border with clinical symptoms of disease, it is sent back to the place<br />
of origin; however, animals that show signs of <strong>FMD</strong> are quarantined and sampled [6].<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 35
Animal products that enter <strong>Brazil</strong> must have a MAPA import permit, comply with all sanitary health<br />
requirements, originate from an establishment approved to export to <strong>Brazil</strong>, and declare the port of<br />
entry and final destination. Animals must be accompanied by a Zoosanitary Certificate as required<br />
in Normative Instruction SDA 31/2002 [3].<br />
According to <strong>Brazil</strong>ian officials, 100 percent of animal products entering the country receive a<br />
primary and a secondary inspection. An inspection for animal health purposes is conducted, which<br />
includes a check for compliance with labeling and packaging requirements. For the secondary<br />
inspection, the product is sent to a storage facility registered with MAPA for public health sampling.<br />
If a shipment is rejected, <strong>Brazil</strong> law authorizes a number of actions. The product may be returned to<br />
its place of origin, may be confiscated and incinerated, or may be retained for possible resolution.<br />
There was no international importation into Santa Catarina of live animals susceptible to <strong>FMD</strong>,<br />
semen, or embryos from January 2005 to October 2006. All registered imports of products and<br />
byproducts are listed table 5 [4].<br />

APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 36
<strong>Brazil</strong>ian law prohibits all transport of animal and plant products from anywhere in the world<br />
without proper permits. Airline passengers are checked for animal and plant products. The type of<br />
inspection depends on the origin of the flight. Shipments arriving by sea are also checked for<br />
animals and animal products, while ship passengers receive random checks for the presence of<br />
animals and animal products. Prohibited items are confiscated, stored, and transported by the<br />
contract company to the incinerator under MAPA supervision. Customs officials X-ray a percentage<br />
of arriving luggage and confiscate prohibited products. They increase the percentage of luggage<br />
undergoing X-ray for flights arriving from high-risk areas such as Spain and Portugal, which have<br />
small artisan farms with no government oversight, or countries with outbreaks. In addition,<br />
passengers from high-risk countries must walk across a disinfectant mat. One hundred percent of<br />
luggage from countries having an <strong>FMD</strong> outbreak goes through X-ray inspection.<br />
Inspection stations<br />
MAPA controls products imported from other countries at the authorized entry points. Prior to<br />
importation, the importer must procure authorization from MAPA. MAPA evaluates the sanitary<br />
conditions of the exporting country as well as the exporting facility. If MAPA authorizes the<br />
importation, the entry point into <strong>Brazil</strong> will be specified on the authorization and MAPA’s<br />
International Agriculture and Livestock Surveillance Service at the point of entry will receive a copy<br />
of the authorization with all the specific sanitary requirements listed. The products must receive<br />
inspection and authorization from the official veterinarian at the point of entry to be released into<br />
Santa Catarina [4].<br />
Permanent inspection stations are located at strategic points along the border of Santa Catarina.<br />
There are 67 permanent inspection stations for import of plants, animals and products into Santa<br />
Catarina (see Figure 8). These stations are staffed by 429 professionals from the official veterinary<br />
services, who work in shifts to provide 24-hour coverage. Operations at each post are coordinated<br />
by an official veterinarian and include police support. The inspection posts have communications<br />
equipment, computers, vehicles, equipment for cleaning and disinfection, and an area for<br />
disinfecting and disposing of confiscated material [4].<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 37
Figure 8: Location of permanent inspection stations<br />
(Source Presentation: CIDASC)<br />
Some of the permanent inspection stations are designated as control points for moving animals and<br />
products through the State. There are 12 of these “sanitary corridors” in Santa Catarina. At these<br />
posts, vehicles are sealed at the entry point and the person in charge of the transportation signs a<br />
liability commitment which identifies the entire route through the State, including the exit inspection<br />
station. The exit station, which is in charge of verifying the integrity of the seal and information on<br />
the exiting cargo, is notified of the shipment by the official in charge of the entry station. In case of<br />
conflicts or the failure of the transiting cargo to arrive at the destination, the State’s health authorities<br />
are immediately notified, initiating the search and apprehension process with involvement of the<br />
official veterinary services at both the origin and destination points of the shipment as well as police<br />
[4].<br />
In addition to the permanent inspection stations, there are also a number of mobile inspection<br />
stations. These are organized by the LVUs and set up at strategic points without advance notice.<br />
They are staffed by official veterinarians and paraveterinarians and include police support [4].<br />
During the 2008 site visit, the site visit team visited two land interstate border inspection posts with<br />
each of the <strong>Brazil</strong>ian States bordering Santa Catarina (Paraná and Rio Grande do Sul) and the<br />
MAPA office at the International Airport Hercilio Luz at Florianopolis. Officials at the sanitary<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 38
corridor inspection posts that were visited demonstrated working knowledge of requirements for<br />
animals and products to enter or transit Santa Catarina. They described the day-to-day procedures<br />
and provided copies of MAPA and CIDASC procedural manuals, personnel logs, and records of<br />
activities. They also outlined the actions that would be taken if a transiting vehicle did not arrive at<br />
the exit point within the appropriate time [11].<br />
The site visit team examined paperwork of exiting vehicles and reviewed seal verification and<br />
removal. The paperwork included the authorization for movement (issued by MAPA), the GTA<br />
(provided by the LVU), and farm certification documents (issued by the local MAPA office in the<br />
State). The site visit team observed that cargo trucks were properly checked and disinfected. The<br />
team also observed that passenger cars are not routinely stopped at border points, but only vehicles<br />
that could carry animals or large amounts of animal products. These vehicles were stopped and the<br />
drivers were asked to open all cargo compartments. However, officials reported that during<br />
outbreaks in neighboring areas (and a corresponding elevation in the risk status of the affected area),<br />
security measures are tightened. Inspectors inspect more passenger vehicles and confiscate more<br />
materials, including items for personal use such as sandwiches. In addition, staff clean and disinfect<br />
all vehicles, not just livestock trucks [11].<br />
Officials at the inspection station reported that any trucks with animals destined to stay in Santa<br />
Catarina (as opposed to transiting the State) would be followed to the destination farm by CIDASC<br />
officials who would break the seal on the farm and oversee the required 14-day quarantine period,<br />
after which the animals may be allowed to move. The wheels and undercarriage of all trucks<br />
carrying animals into Santa Catarina for any reason are disinfected on entry. The disinfection<br />
equipment and procedures were demonstrated during the visit [11].<br />
If confiscated materials exceed the local inspection post’s ability to properly disinfect and dispose of<br />
them on site, the entire shipment will be directed to a local renderer for autoclave sterilization. The<br />
official veterinarian on site will issue a seizure document and contact the highway police to escort<br />
the truck to the plant. The plant will issue a document of inactivation, which is returned to the<br />
inspection post. The shipper will also be fined. The border post with Rio Grande do Sul had not had<br />
to do this and had no records to show the site visit team. Smaller amounts of confiscated material<br />
are usually inactivated on site with iodine and buried. This process was demonstrated to the site visit<br />
team [11].<br />
Actions taken in the case of illegal entry<br />
All animals susceptible to <strong>FMD</strong>, animal products and byproducts, veterinary products and materials<br />
or substances that can carry the <strong>FMD</strong> virus coming into Santa Catarina that are not in compliance<br />
with current legislation are slaughtered or destroyed at the discretion of the official veterinary<br />
service and in accordance with the risk represented by the animal or product (Normative Instruction<br />
SDA 05/2003). The results of inspection activities carried out in 2005 and the first half of 2006 are<br />
shown in Table 6.<br />

Conclusions:<br />
APHIS concludes that CIADSC has adequate controls at ports of entry for legal importation of<br />
species and products that could carry the diseases under evaluation. Santa Catarina also has the legal<br />
framework and authority to deal with the entry of illegal animal or animal products into the State.<br />
8. Livestock demographics and marketing practices in the region<br />
Market practices and movements within the State could lead to exposure to or spread of diseases. In<br />
this section we explain the livestock demographic practices and the type of production systems in<br />
different areas of Santa Catarina.<br />
General information<br />
The livestock population of Santa Catarina is shown in Table 7. There are currently 178,945 rural<br />
holdings in the State that are registered in CIDASC and contain one or more species susceptible to<br />
<strong>FMD</strong>. Included among these are over 75,000 holdings that contain domestic pigs or wild boar, both<br />
of which are susceptible to <strong>FMD</strong>, CSF, ASF, and SVD. Eighty percent of the total number of<br />
registered holdings have been georeferenced by CIDASC [4].<br />

The density distributions of holdings containing various types of livestock within Santa Catarina,<br />
broken out by species, is provided in Figure 9. The total population of susceptible species within<br />
Santa Catarina is 5,250,000 domestic swine; 2,750,000 cattle; 196,000 sheep, 37,000 goats, and<br />
16,000 farmed wild boar [4].<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 41
Figure 9: Density distribution of human, swine, cattle, sheep and goat populations in<br />
Santa Catarina [4]<br />
Santa Catarina is primarily known for its swine production. The swine population of Santa Catarina<br />
is approximately twice the size of its cattle population. While the State provides almost 30 percent<br />
of <strong>Brazil</strong>’s pork industry, it contains less than 3 percent of the country’s cattle industry. Although<br />
the zebu cattle breeds predominate in most of <strong>Brazil</strong>, European breeds are more common in Santa<br />
Catarina [10]. Most of Santa Catarina’s cattle are dairy cattle. The State contains 97 federally<br />
inspected and 60 State inspected dairy facilities. The State produces approximately 1.5 billion liters<br />
of pasteurized milk annually [4].<br />

<strong>Brazil</strong> has the largest swine herd in Latin America, with the majority of the production concentrated<br />
in the southern and southeastern regions of the country, primarily Santa Catarina (Figure 11).<br />
Figure 11. Distribution of swine population [9]<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 43
The majority of Santa Catarina’s swine industry consists of a vertically integrated production system<br />
from breeding stock to processing (85 percent of the State’s producers operate under such a system<br />
according to officials interviewed during the 2008 site visit). In this system, a certified breeding<br />
farm, or GRSC, produces breeding animals and distributes them to piglet production units (UPLs).<br />
The GRSCs are highly controlled facilities that produce all of the breeding/grandparent stock for all<br />
aspects of production within the cooperative [11, 13].<br />
There are no animals introduced to the GRSCs; they use their own genetics. Biosecurity<br />
requirements for GRSCs, as provided in Normative Instruction No. SDA 19/2002, include<br />
requirements for peripheral fencing, a single entry point for people and vehicles with an appropriate<br />
disinfection system, a loading and unloading station next to the fence, and disinfection for materials<br />
and equipment. In addition, a locker room and shower facility with impermeable floors must be<br />
available for visitors to shower in. Visitors must shower twice before entering the facility, once at a<br />
nearby hotel and then again within the facility. Visitors must also shower before leaving the facility.<br />
Visitors must complete a form describing the date and place of visits to facilities containing pigs (no<br />
one can visit such a facility more than once within 24 hours). Clean water must be available.<br />
Finally, the facility must be licensed by the environmental department for treating and disposing of<br />
waste. A system must be in place for proper disposal of dead animals.<br />
GRSCs must conduct routine testing for CSF, Aujesky’s disease, brucellosis, TB, scabies, and<br />
leptospirosis every six months. Additionally, GRSCs will lose their certification if a slaughter plant<br />
or feed mill locates too close or is classified as an at-risk facility for any reason. There are 306<br />
GRSCs in <strong>Brazil</strong> within the CSF-free zone. The majority of them (136) are located within Santa<br />
Catarina [11].<br />
The cooperative production system is governed by contract, with the parent company guaranteeing<br />
the supply of piglets, feed, and veterinary assistance [13]. The cooperative agencies involved in the<br />
production systems reviewed during the site visit included many aspects of agriculture, including<br />
crop production and the rearing of different livestock species. The parent company has minimum<br />
biosecurity standards, which they help the small producer to meet and maintain. Additional<br />
requirements for participation in the cooperative include minimum traceability requirements,<br />
required reporting of disease or production problems to the company veterinary representative (plus<br />
concurrent notification of CIDASC in the event of a vesicular or hemorrhagic disease), and the<br />
producer’s periodic training in disease and production measures. Cooperative company<br />
veterinarians are trained by official veterinarians from CIDASC.<br />
During the 2008 site visit, the team visited several individual facilities operating within an integrated<br />
system, including farrowing farms, finishing operations, and UPLs. Some of the facilities were<br />
involved in all phases of production and some included other species, primarily dairy cattle. All of<br />
the farms visited followed (or were implementing) basic biosecurity measures required by the<br />
cooperative, such as perimeter fencing, footbaths or lime, and vehicle wash stations at the entry. In<br />
addition, representatives of the cooperative provided protective clothing and footwear. The UPLs<br />
and the GRSC facilities maintained more intense biosecurity measures, including showering and<br />
additional clothing requirements [11].<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 44
The cooperative farm producers kept records of births and mortalities as well as all veterinary visits<br />
and all treatments provided. They were willing to contact their company veterinarian with any<br />
animal health questions or disease suspicions. The company veterinarians, in turn, expressed close<br />
relationships with the LVU veterinarians and would help them should they encounter an issue of<br />
concern [11].<br />
During the site visit, official veterinarians and producers reported that producers often relied on<br />
official veterinarians rather than private veterinarians to provide diagnostic services because the<br />
State veterinary service was free. In addition, since most of the swine farms are integrated, they<br />
receive frequent official visits, and when needed, will call the company veterinarians or<br />
paraveterinarians employed by the corporation. During farm visit inspections the official<br />
veterinarian or paraveterinarian educates the producer and staff as necessary regarding the signs of<br />
disease and reporting requirements, and checks animal health, records (including copies of GTAs),<br />
and current inventory [11].<br />
The farming of wild boar in Santa Catarina is controlled by the <strong>Brazil</strong>ian Institute of Environment<br />
and Renewable Natural Resources, which operates under the Ministry of the Environment. The total<br />
population of wild boar numbers approximately 16,500 animals, most of which reside in the middle<br />
western part of the State [13].<br />
The 2008 site visit team visited a wild boar facility. This facility handled all aspects of pig<br />
production. The producer delivered pigs to a local slaughter plant when enough animals became<br />
available to warrant the movement. The facility had a perimeter fence of cement block topped with<br />
chain link and similar fencing among the houses. The farrowing facilities consisted of open pens<br />
with solid block walls separating them and a nursery area for the newborn piglets. Pig rearing areas<br />
consisted of solid block foundation with metal bars. Lime was used at the entrances to the pig<br />
houses to prevent entry of contaminants [11].<br />
The <strong>Brazil</strong>ian sheep flock consists of approximately 14.8 million animals and is concentrated in the<br />
southern region of the country, especially in Rio Grande do Sul. The goat population consists of<br />
approximately 12.1 million animals and is concentrated in the northeastern region of <strong>Brazil</strong>. Most<br />
small ruminants are produced for the internal market [5, 10].<br />
Animal identification<br />
<strong>Brazil</strong> is implementing the SISBOV national identification system for cattle and buffalo. SISBOV’s<br />
goal is to individually identify and monitor all cattle and buffaloes born or imported into <strong>Brazil</strong>. The<br />
system is designed to trace animals from birth to death. A unique 17-digit identification code is<br />
given to each animal and is registered in a national database managed by MAPA. Additionally, the<br />
system includes information on the owner’s registration, date and place of the animal’s birth, breed<br />
characteristics, feeding practices, vaccination data, movement records, death information, and other<br />
animal health indicators [6, 12].<br />
MAPA accredits private companies to assign the codes and collect the relevant information. There<br />
are eight accredited companies. The companies select the type of identification used and certify the<br />
status of each animal enrolled. MAPA audits the companies regularly. A visit by a veterinarian is<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 45
equired to register the animals [7, 11]. Participation in the program is voluntary, but <strong>Brazil</strong>ian<br />
officials intend to make it mandatory at the national level. At the present time, all farms and animals<br />
that export to the European Union (EU) must participate [6, 12].<br />
Identified animals that move to slaughter are issued a SISBOV card. The slaughter facility checks<br />
the documentation and terminates the registration of slaughtered animals in the national database. If<br />
the slaughter facility is not federally inspected, the accredited company terminates the registration of<br />
slaughtered animals [12].<br />
Santa Catarina producers use SISBOV tags (provided by MAPA) for identification. The tags are not<br />
registered with the SISBOV system unless the animals are exported. Individual farmers are required<br />
to apply tags and maintain an inventory. The LVU distributes the tags along with a listing of tags by<br />
number. MAPA is working with the swine industry to define ear tag use in pigs to be exported to<br />
the European Union. Farmers must place the ear tags on the animals, maintain tag inventories, and<br />
report all movements, including births, to the LVU within 30 days. The farmer must also report the<br />
loss of a tag, as well as the death or slaughter of an animal (along with its tag number) to the LVU.<br />
Santa Catarina’s animal identification system was fully implemented at the end of 2008 [11].<br />
Slaughter inspection<br />
There are 58 slaughterhouses for swine in Santa Catarina. These include 18 federally inspected<br />
slaughterhouses (SIF) and 40 using the State inspection service (SIE). For cattle, the State has four<br />
SIF slaughterhouses and 34 SIE facilities, and for small ruminants, a total of 10 SIE slaughterhouses.<br />
The health inspection of these establishments is carried out by 126 official veterinarians, with 79<br />
official paraveterinarians and 459 hired employees [4]. (See Figure 12 for the location of slaughter<br />
plants within Santa Catarina.)<br />
Figure 12: Distribution of SIE and SIF slaughterhouses for swine and beef [4]<br />

Animal gathering points<br />
In Santa Catarina, CIDASC inspects most fairs, exhibitions, and events where animals are gathered.<br />
In 2005 and 2006 there were 162 such events, involving 83,449 bovines and 2,949 small ruminants<br />
(Table 8). All animals are inspected and have their health documents checked on arrival by a<br />
representative of the official veterinary service. The representative is present during the entire event<br />
[4].<br />

Conclusions:<br />
The livestock industry in Santa Catarina appears to be well organized and knowledgeable of<br />
necessary biosecurity precautions. APHIS finds that different controls and biosecurity measures at<br />
commercial swine farms effectively mitigate introduction and spread of the diseases under<br />
evaluation. The slaughter inspection system is robust. Animal identification systems are<br />
comprehensive and allow officials to trace the movement of cattle and swine within Santa Catarina.<br />
Further, APHIS concludes that Santa Catarina has adequate control of inspection activities within<br />
integrated production systems, animal concentration points, and slaughter plants.<br />
9. Disease surveillance in the region<br />
Documenting surveillance systems that ensure early detection of the diseases under consideration is<br />
essential for the risk assessment. This section explains the characteristics of the <strong>FMD</strong>, CSF, SVD,<br />
and ASF surveillance programs in Santa Catarina.<br />
<strong>FMD</strong><br />
<strong>Brazil</strong> employs both passive and active surveillance strategies designed to demonstrate freedom from<br />
<strong>FMD</strong>. The strategies’ emphases differ depending on the phase of the eradication process within a<br />
given State or zone. During the first phase, the zone demonstrates its freedom from disease. The<br />
second phase consists of monitoring of the zone. The second phase begins once the zone is free<br />
from infection and is recognized as free of <strong>FMD</strong> by the OIE, either with or without vaccination<br />
(Santa Catarina is recognized as free without vaccination). The primary goal of the first phase is to<br />
document freedom from disease while the second phase prevents the reintroduction of the disease,<br />
maintains good sanitary conditions, and provides technical grounds to demonstrate the continual<br />
absence of disease and viral activity in the zone.<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 47
The first phase relies on active surveillance while the second phase uses both active and (mainly)<br />
passive surveillance. Active surveillance complements passive surveillance primarily by targeting<br />
specific “high-risk” areas within the zone for serological sampling and more in-depth investigations.<br />
Santa Catarina is currently in the second phase; therefore, the emphasis is on passive surveillance for<br />
<strong>FMD</strong>.<br />
The surveys and monitoring carried out in <strong>Brazil</strong> follow the guidelines for <strong>FMD</strong> surveillance<br />
contained in Annex 3.8.7 of the Terrestrial Code of the OIE. <strong>Brazil</strong> uses the I-ELISA 3ABC<br />
(enzyme-linked immunosorbent assay test for detecting <strong>FMD</strong>V nonstructural proteins 3ABC) and<br />
the EITB (enzyme-linked immunoelectrotransfer blot) system developed by PANAFTOSA as the<br />
diagnostic method to test for antibodies against non-structural proteins of the <strong>FMD</strong> virus. The two<br />
tests are conducted consecutively. The I-ELISA 3 ABC screens for the disease and the EITB is used<br />
for confirmation. As a complementary test in animals testing positive for non-structural proteins, the<br />
ELISA CFL (ELISA liquid phase competition) is used to determine antibody titers for the three viral<br />
strains prevalent in South America and used in the vaccine. Samples of esophageal-pharyngeal<br />
liquid are collected for viral testing [4].<br />
All animals sampled, whether through passive or active surveillance, are individually identified and<br />
examined by an official veterinarian. The holding cannot sell sampled animals during the testing<br />
period [4].<br />
Active surveillance<br />
Active surveillance for <strong>FMD</strong> in <strong>Brazil</strong> consists mainly of targeted serologic surveys conducted<br />
primarily in specific “high-risk” farms within the zone under evaluation. Serological testing is also<br />
conducted whenever there is a suspicion of disease. High-risk farms are defined as those that:<br />
Have a high volume of movement of animals or their products<br />
Are located close to animal or waste-gathering facilities, such as<br />
o Slaughterhouses<br />
o Livestock event centers<br />
o Feed mills<br />
o Highways<br />
o Landfills<br />
o International borders<br />
o Borders with States where the disease is present<br />
Engage in a high level of breeding activities<br />
Contain over 100 cattle or multiple species<br />
The first survey to assess the circulation of the <strong>FMD</strong>V in Santa Catarina was carried out in 1997<br />
with Rio Grande do Sul to meet the OIE’s requirements for establishing an <strong>FMD</strong>-free zone where<br />
vaccination is practiced. Another survey was carried out in Santa Catarina in 2002, after an outbreak<br />
of the disease in Rio Grande do Sul, and serologic monitoring was performed in 2003 and 2004. In<br />
2006, a new serological survey was carried out to evaluate viral circulation, so that Santa Catarina<br />
could be declared <strong>FMD</strong>-free without vaccination. Samples were collected during November and<br />
December [4].<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 48
Three geographical sampling strata were established for the survey. An independent survey was<br />
carried out within each stratum using a two-stage cluster sampling design with the following<br />
statistical parameters: 95 percent confidence level; 95 percent sensitivity of the diagnostic system;<br />
100 percent specificity; expected prevalence among herds of at least 2 percent; and expected<br />
prevalence within herds of at least 5 percent. About 468 primary sampling units consisting of 1,347<br />
holdings were established throughout the State. A total of 11,059 samples were collected, out of<br />
which 48 were determined to be reactors to I-ELISA 3ABC/EITB testing [4].<br />
Figure 13 depicts the three sampling strata and the location of primary sampling units, including<br />
those where a positive reactor was found in Santa Catarina during the 2006 study.<br />
Figure 13: Sampling strata and location of sampling units, Santa Catarina, 2006 [4]<br />
In locations where at least one animal reacted to the serologic sampling, a complementary<br />
investigation was carried out which included detailed clinical inspection of all sampled and<br />
susceptible animals on the farm. None of the animals showed any evidence of vesicular disease.<br />
The high susceptibility of the cattle herd in Santa Catarina coupled with the low number of reactive<br />
animals, and the absence of clustering as supported in complementary investigations and analyses,<br />
led <strong>Brazil</strong>ian authorities to conclude that the <strong>FMD</strong> virus was not circulating in the population at the<br />
time of the survey [4].<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 49
Passive surveillance<br />
Passive surveillance is the primary form of evaluation conducted during the second phase of <strong>FMD</strong><br />
eradication, and involves monitoring for disease. Many individuals carry out this phase of<br />
surveillance using many different types of activities, including:<br />
Animal movement control activities<br />
Farm inspections<br />
Slaughterhouse inspection<br />
Inspections during livestock fairs [6]<br />
High-risk farms receive more visits during passive surveillance. Because passive surveillance relies<br />
heavily on community participation and similar inputs through the LVU, officials try to keep the<br />
level of community participation high and the participants informed of both the suspicious signs of<br />
disease and its reporting requirements. For example, in 2002, the official service held 9,702<br />
seminars, reaching 213,131 people, with an average of 23 participants per event [7].<br />
Any suspicion of vesicular disease must be immediately reported to the official veterinary services<br />
(or in the case of animal owners or handlers, to their private veterinarian, who must then report a<br />
continued suspicion to the official service). Animal owners or those responsible for the animals who<br />
fail to report suspicious cases of officially notifiable diseases, such as <strong>FMD</strong> or SVD, are subject to<br />
State civil penalties and may also be charged under the <strong>Brazil</strong>ian Penal Code. Veterinarians may<br />
also face disciplinary sanctions by the Veterinary Medicine Regional Councils [4].<br />
There are several participants in the vesicular disease surveillance system in <strong>Brazil</strong>:<br />
Cattle raisers, owners of susceptible animals, and rural workers who handle the animals<br />
Official employees, as part of their duties while visiting farms or animal gatherings (such as<br />
shows, auctions, and exhibitions)<br />
Contracted, approved or official vaccinators<br />
Technicians<br />
Representatives of rural communities, especially those who work in cattle holdings and<br />
receive training from the official veterinary service<br />
Slaughterhouse employees<br />
Official employees who check the movement of animals and their products and byproducts in<br />
permanent inspection stations and on mobile inspection teams<br />
Veterinarians, paraveterinarians and other private sector professionals who work with animal<br />
health [4]<br />
Records of notifications submitted to the official veterinary service are kept at LVUs and include<br />
information about the time of notification, the location of the holding or premises where the animals<br />
are kept, the species involved, the type of notification (by owner, veterinarian, or third party), how<br />
the notification was made (personally, by phone, or otherwise), and an initial description of the<br />
event. After receiving the notification, official service veterinarians must respond to the suspicion as<br />
soon as possible. This response is usually immediate, especially if the report is made during<br />
business hours, but must be made within 12 hours regardless of weekends or holidays. A vesicular<br />
disease suspicion kit is available in all LVUs and includes the necessary equipment to hold the<br />
animal, collect samples, take appropriate biosafety measures, and record the collected information.<br />
A standard national notification form is used. The kit also includes a manual detailing the steps to<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 50
follow on notification of vesicular disease suspicions, including the appropriate information flow<br />
and the technical procedures to be followed. All official veterinarians are trained in carrying out this<br />
initial response [4].<br />
After completing the initial records and before leaving the field, the official service veterinarian on<br />
site will inform his or her work team, immediate superior, and the regional representative of the<br />
emergency diseases group about the suspicion. Until the investigation has been completed, animals<br />
cannot be moved from the holding, from any adjacent holdings, or other holdings that have traded<br />
animals, products, or equipment with the affected holding [4].<br />
Once the disease suspicion has been ruled out, the official services veterinarian records the final<br />
diagnosis, lifts the animal movement restrictions on the affected and related holdings, and<br />
communicates the results to his or her immediate superior, work team, and the regional<br />
representative of the special group for emergency diseases. Most investigations concern false<br />
reports, traumatic injuries, intoxication and malnutrition rather than actual OIE reportable disease<br />
[4].<br />
If the official veterinarian determines that a disease suspicion is valid and needs to collect specimens<br />
for laboratory analysis, the involved holdings will remain under quarantine until testing is completed<br />
and negative results returned. Positive results would extend the quarantine until disease control<br />
measures are completed. The veterinarian immediately sends the laboratory materials, along with<br />
the appropriate submission forms, to a MAPA laboratory. The official veterinary service sends<br />
additional teams to provide extra surveillance around the primary holding and investigate the<br />
movement of susceptible animals in and out of the affected holding within the 60 days prior to the<br />
most probable first occurrence of the disease [4].<br />
If the investigation confirms <strong>FMD</strong>, an animal sanitary emergency state is established during the<br />
completion of the investigation and eradication efforts. If tests do not detect <strong>FMD</strong>, differential<br />
diagnostic tests are carried out for vesicular stomatitis, bovine viral diarrhea, infectious bovine<br />
rhinotracheitis, and bluetongue. Specific procedures exist for each of these diseases and would be<br />
carried out if any of the diseases were detected [4].<br />
Santa Catarina reported 83 notifications of reportable disease suspicions in holdings with <strong>FMD</strong>susceptible<br />
animals in 2005. These notifications were investigated. Thirty involved a report of<br />
possible vesicular disease. Of the vesicular notifications, none were confirmed to be <strong>FMD</strong>. Instead,<br />
13 were determined to involve trauma and 17 involved a variety of toxic plant exposures. In 2006<br />
there were 201 notifications of suspicious reportable diseases in holdings containing <strong>FMD</strong>susceptible<br />
animals. Eighty-one of these were related to possible vesicular disease with 41<br />
eventually determined to involve trauma and the remaining 40 to involve toxicosis [4].<br />
Official veterinary services staff also conduct inspections during their regular duties. These duties<br />
include control of animal movement at permanent inspection stations or by mobile inspection teams;<br />
antemortem and postmortem activities at slaughterhouses; supervision of livestock congregations;<br />
and direct inspection at rural holdings [4].<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 51
In addition to responding to reportable disease suspicions, official veterinary services staff also<br />
conduct inspections during routine surveillance activities (while updating inventory numbers<br />
provided by the farmer to the local veterinary unit) and certification of holdings as part of specific<br />
sanitary programs. None of these visits detected any clinical signs compatible with vesicular or<br />
notifiable disease [4]. Information on the number of rural holdings inspected by the official<br />
veterinary service in 2005 and 2006 is provided in Table 9.<br />

To ensure that members of the public that have contact with animals know the signs of the diseases<br />
under evaluation as well as their obligation to report any suspicion of such diseases, the official<br />
veterinary service held 323 lectures and technical meetings, reaching 42,223 people in 2005, and 325<br />
lectures, involving 44,258 community participants, in 2006. In addition, the official veterinary<br />
service is implementing several educational projects, including plans to create and maintain<br />
community support resources by fostering municipal commissions of animal health, training and<br />
maintaining health technicians, and creating a health education plan in schools [4].<br />
Santa Catarina operates a 24-hour hotline for reporting suspicions of notifiable animal diseases<br />
(particularly for the notification of suspect <strong>FMD</strong> cases). This service began in May 2001, and from<br />
that time until November 2006 community members made 116 reports. All reported incidents have<br />
been recorded, including the date and time of the report, history of the report, and actions taken<br />
regarding the event [4].<br />
CSF<br />
<strong>Brazil</strong> carries out passive surveillance for CSF, particularly at the border between the CSF-free zone<br />
and the infected region (see Figure 6). The border of the CSF-free zone corresponds to that of the<br />
<strong>FMD</strong>-free zone; therefore, sanitary defense staff and programs can control of the entry of susceptible<br />
animals and products for both diseases [3].<br />
MAPA coordinated serologic surveys in 2000 and 2003 to delineate and maintain the free zone. The<br />
surveys were conducted in accordance with the OIE’s statistical parameters. These include a<br />
confidence level of 95 percent, specificity of 100 percent, and sensitivity of 95 percent at a<br />
prevalence of 1 percent among farms. The target population included the entire hog and wild boar<br />
population within the free area, except for those in GRSC farms, which are officially and<br />
individually certified as free from diseases. The number of samples collected in each investigation<br />
was approximately 28,000 (Table 10) [3].<br />

Diagnostic tests are conducted at official public service laboratories. Screening tests are performed<br />
using an ELISA for the detection of antibodies to the CSF virus (IDEXX). Any reactive or<br />
suspicious samples are submitted for differential diagnosis using virus-neutralization tests in cell<br />
cultures for bovine viral diarrhea and CSF. Additionally, if the screening test returns a suspicious<br />
result, a confirmatory test will be performed. The farm that provided the sample will undergo<br />
serologic evaluation of additional susceptible animals. The laboratory will also attempt to isolate the<br />
virus [3].<br />
Pursuant to Decree No. 24.548, and as with <strong>FMD</strong> and other vesicular diseases, every citizen must<br />
report the suspicion of CSF to the nearest LVU. If the owner of the animals fails to report the<br />
suspicion of disease, he or she will lose a claim to indemnity if the herd must be destroyed to control<br />
the disease. Veterinarians and other field professionals may be subject to legal action before their<br />
respective trade guilds [3].<br />
If a sanitary emergency or documented disease event occurs, blood samples are collected from all<br />
animals on the farm, both sick and healthy exposed animals, to allow for a comparison of antibody<br />
titers. Samples are frozen and sent to the Laboratório Nacional Agropecuário in Recife, in<br />
Pernambuco, outside the CSF-free zone. Sick animals are killed and tonsils, spleen, lymph nodes,<br />
kidneys, and the distal portion of the ileum are collected and submitted for virus isolation [3].<br />
As with <strong>FMD</strong>, all suspicious cases of CSF or other diseases with similar clinical signs must be<br />
investigated by the official veterinarian. The investigation must be initiated within 12 hours of the<br />
report and must be conducted using appropriate biosecurity. If the responding official cannot<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 53
dismiss the suspicion of disease on clinical examination of the animals on the farm, he or she must<br />
collect the appropriate samples, issue a quarantine, and immediately communicate the event to the<br />
higher sanitary authority [3]. The official veterinarian must also fill out the Initial Disease<br />
Investigation Form, collect information on the premises under suspicion, prohibit the movement of<br />
hogs, their products and byproducts from the property, clean and disinfect the equipment and<br />
materials used in examinations and specimen collection, incinerate expendable work clothes, and<br />
keep outsiders out of the facilities [3].<br />
Santa Catarina reported three CSF notifications in 2007, as shown in the table below. Followup tests<br />
were negative for CSF and the implicated farms received post-investigation evaluations by the<br />
official veterinary service [13].<br />
Table 11. Number of notifications of suspected CSF in Santa Catarina, 2004-March 2008 [13]<br />

<strong>Brazil</strong> does not routinely test for SVD since the disease is exotic to <strong>Brazil</strong>. However, the country<br />
carries out passive surveillance in a manner similar to that conducted for other vesicular diseases, as<br />
detailed above. If <strong>FMD</strong> is ruled out as a diagnosis in clinically affected pigs, evaluation for SVD is<br />
included as part of the followup testing. In suspicious cases, movement of animals from the<br />
involved farms and the region is restricted until a definitive diagnosis is reached [13].<br />
ASF<br />
For ASF, which is also an exotic disease, no specific surveillance is conducted. Instead, if CSF is<br />
ruled out in the susceptible population, ASF is considered as a possibility and investigated as such.<br />
As with SVD and other notifiable diseases, any implicated farms as well as those associated with<br />
them undergo movement restrictions until the investigation is completed and a final diagnosis<br />
achieved [13].<br />
Conclusions:<br />
APHIS concludes that the serologic sampling conducted in Santa Catarina for <strong>FMD</strong> and CSF is valid<br />
and the sampling coverage is adequate. As with <strong>FMD</strong>, all suspicious cases of CSF or other diseases<br />
with similar clinical signs must be investigated by the official veterinarian. SVD surveillance is<br />
addressed within the passive surveillance system for other vesicular diseases. ASF surveillance is<br />
combined with CSF surveillance. Furthermore, given the historical absence of the diseases under<br />
evaluation in the region, quick detection of clinical signs should disease be introduced in the absence<br />
of vaccination would provide further evidence of freedom of the diseases under evaluation in Santa<br />
Catarina.<br />

10. Diagnostic laboratory capacity<br />
The laboratory system, including test procedures for the diseases under evaluation, quality assurance<br />
measures, and official oversight procedures, must be clearly documented to provide confidence in<br />
disease surveillance activities and the ability to quickly detect and confirm a disease outbreak. This<br />
section explains the laboratory capabilities of Santa Catarina for diagnosing and detecting <strong>FMD</strong>,<br />
CSF, SVD, and ASF.<br />
General information<br />
<strong>Brazil</strong>’s Ministry of Agriculture has three laboratories that perform diagnostic tests for <strong>FMD</strong>. These<br />
laboratories are located in Pedro Leopoldo, Pará, and Recife. The PANAFTOSA laboratory in Rio<br />
de Janeiro is the reference laboratory. The laboratory in Recife performs CSF serological testing,<br />
and SVD and ASF testing if necessary.<br />
<strong>Brazil</strong>’s laboratories perform the following routine <strong>FMD</strong> tests:<br />
Virus typing: Complement fixation and ELISA test (double antibody sandwich ELISA).<br />
Assessment of antibody level: ELISA test in liquid phase (blocking ELISA) and serum<br />
neutralization.<br />
Detection of viral activity through the anti-virus infection associated antigen (VIAA),<br />
ELISA 3ABC, and EITB tests.<br />
Identification of the virus in esophageal-pharyngeal fluid through the Probang test.<br />
Four State laboratories are part of a network of authorized laboratories that perform certain <strong>FMD</strong><br />
diagnostics to admit animals into the export region and for serological monitoring. The laboratories<br />
perform EITB and VIAA tests and began ELISA 3ABC testing in 2002. Only MAPA laboratories<br />
carry out diagnostic activities in response to suspected outbreaks of vesicular diseases and as a part<br />
of viral activity studies to implement free zones.<br />
The 2002 site visit team visited three of the abovementioned laboratories [6] and reported the<br />
following:<br />
Diagnostic laboratory in Pedro Leopolodo, Minas Gerais:<br />
This Federal laboratory had a biosafety level (BSL) 2 facility for bacteriology<br />
(brucellosis and TB testing) and chemistry laboratory.<br />
The staff had about 94 people.<br />
Behind the BSL-2 facility, a new BSL-3 laboratory was under construction.<br />
The laboratory was about 2,500 square meters in size and had nine laboratories with a<br />
double airlock and a separate air zone for each laboratory. There was a separate animal<br />
facility with a separate entrance.<br />
The facility had three rooms for large animals with an individual shower for each room,<br />
and three rooms for small animals with a common shower in the hallway.<br />
The necropsy room had two oversized autoclaves for decontaminating carcasses.<br />
HEPA filters and the mechanical room were located on the third floor.<br />
The basement had three 3,000-gallon tanks for decontaminating effluent by boiling at<br />
100C.<br />
Animal Products Analysis Laboratory (LAPA/Recife), Pernambuco<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 55
This Federal laboratory conducted <strong>FMD</strong> serology for all of <strong>Brazil</strong> except the northern<br />
part, where <strong>FMD</strong> was considered endemic.<br />
Vaccine efficacy was assessed in 5- to 7-day-old mice. <strong>FMD</strong> vaccine safety testing was<br />
tested in the baby hamster kidney-21 (BHK-21) cell line.<br />
At the time of the visit, the laboratory had five professional staff and three technicians.<br />
They tested 30,000 serum samples per month for <strong>FMD</strong> serology.<br />
Criteria for conducting followup on the positive samples seemed correct and well carried<br />
out through EITB and ELISA confirmatory tests. The laboratory used virus isolation,<br />
ELISA, complement fixation and IDGA to confirm vesicular disease diagnosis from the<br />
regional authorized laboratories.<br />
The laboratory was also equipped to run the highly sensitive suckling mice inoculation<br />
technique for antigen detection, which is used for vaccine security tests.<br />
The laboratory used ELISA, complement fixation, virus isolation and seroneutralization<br />
assays to diagnose differential diseases such as infectious bovine rhinotracheitis, bovine<br />
viral diarrhea virus and vesicular stomatitis virus.<br />
The 2008 site visit team visited the Recife laboratory in Pernambuco and found:<br />
The laboratory visited provides <strong>FMD</strong> and CSF serology and <strong>FMD</strong> vaccine efficacy for all<br />
of <strong>Brazil</strong> except for the northern part, where <strong>FMD</strong> is endemic.<br />
The laboratory is working under MAPA Regulation N 0 1 issued January 16, 2007; 2 0<br />
Art.; 5,741 Decree of March 30, 2006, and according to the process n 0<br />
21000.004072/2005-19, which defines the criteria for accreditation of MAPA’s national<br />
agricultural laboratories (Laboratorio Nacional Agropecuario, or LANAGRO). An<br />
independent agency regularly audits facilities under this regulation.<br />
The laboratory also diagnoses:<br />
o <strong>FMD</strong>V and its differentials vesicular stomatitis virus, bovine viral diarrhea virus, and<br />
bovine rhinotracheitis virus;<br />
o CSFV and its differentials Aujeszky’s disease, swine colibacillosis, porcine erysipela,<br />
pasteurellosis and salmonellosis; and<br />
o 17 other animal diseases.<br />
<strong>Brazil</strong> has five <strong>FMD</strong>V vaccine plants in production. Two are close to Santa Catarina, one<br />
in Parana and one in Matto Grosso do Sul. The laboratory visited provided vaccine<br />
efficacy for each lot of <strong>FMD</strong>V vaccine produced.<br />
The laboratory tests vaccine efficacy and potency using inoculation in 5- to 7-day-old<br />
mice and seroneutralization titers in sera from the vaccinated animals. The animals are<br />
not given live virus.<br />
<br />
<br />
<br />
<strong>FMD</strong> vaccine safety is tested using the BHK-21 cell line.<br />
CSFV vaccine is produced only for export. The laboratory visited does safety tests in cell<br />
cultures and potency tests with live virus challenges to vaccinated pigs, in facilities<br />
located in endemic areas of the country. Although these techniques differ from OIE<br />
recommendations, the site visit team considers them adequate because of the limitations<br />
of BSL-3 agriculture animal facilities and the cost of bovine test techniques.<br />
The laboratory has 27 professional staff members and 110 technicians or supporting<br />
personnel. Seven professionals (veterinarians and chemical and agronomic engineers)<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 56
provide CSFV-<strong>FMD</strong>V diagnostics. These individuals have been working at the<br />
laboratory for at least 10 years.<br />
The laboratory is old but well maintained and reasonably equipped.<br />
The site visit team found the laboratory personnel highly qualified and motivated. The<br />
team also found that they have the equipment necessary to detect disease.<br />
The turnaround time for results is excellent, avoiding the extension of quarantine time on<br />
farms and States affected by an epidemiological alert.<br />
The laboratory has SOPs (standard operating procedures) and QA (quality assurance)<br />
control for, at least, the two tests the site visit team scrutinized. The procedures for<br />
CSFV and <strong>FMD</strong>V diagnosis are well established and are suited for both detection and<br />
confirmation of the etiologic agent. They are:<br />
o <strong>FMD</strong>V: Surveillance and transport certificates and sera samples are sent to<br />
accredited laboratories in Rio Grande do Sul, Sao Paulo, Minas Gerais and Mato<br />
Grosso. Inconclusive ELISA/ITB results go to Recife. If a clinical case is reported,<br />
the DSA direct that the samples be sent to LANAGRO to perform VIAA or ELISA<br />
3ABC/EITB. If a case ends up with suspected positive results, an alert is sent to the<br />
DSA and CGAL (General Coordination for Animal Laboratories) authorities who in<br />
turn will implement their control and eradication policies.<br />
o CSFV: The same accredited laboratories perform ELISA for CSFV antibodies in<br />
sera. Any serum-positive or inconclusive result is sent to LANAGRO-Recife for<br />
confirmation. If a clinical case is reported, the samples go to LANAGRO-Recife<br />
only, where VIAA, virus neutralization, and/or ELISA are performed. If the result is<br />
confirmed as positive, the authorities take the appropriate measures for control and<br />
eradication.<br />
Conclusions:<br />
APHIS concludes that <strong>Brazil</strong> has the diagnostic capability to adequately test samples for the<br />
presence of the <strong>FMD</strong>, CSF, SVD, and ASF virus. The laboratories in Pedro Leopoldo, Pará, and<br />
Recife have adequate diagnostic capabilities to test samples for the <strong>FMD</strong> virus, including adequate<br />
quality control activities, laboratory equipment, and sufficient staff. The Recife laboratory has<br />
adequate diagnostic capabilities to test samples for <strong>FMD</strong> and other swine notifiable diseases. The<br />
tests used to investigate evidence of viral activity are consistent with OIE guidelines. The staff<br />
members at the facilities visited in 2002 and 2008 were well trained and motivated. The laboratories<br />
have sufficient quality control activities, routinely monitor and calibrate laboratory equipment, have<br />
sufficient staff, have an effective and efficient recordkeeping system for storage and retrieval of data,<br />
and turn samples around quickly.<br />
11. Policies and infrastructure for animal disease control in the region<br />
Each country should have contingency plans in place to limit any disease outbreak. In this section<br />
we provide an overview of the elements of Santa Catarina’s emergency plan if suspect cases of<br />
<strong>FMD</strong>, CSF, SVD, and ASF are identified.<br />
The <strong>Brazil</strong>ian government has developed a Federal contingency plan for <strong>FMD</strong> and CSF. Each State<br />
also drafts a specific contingency plan for immediate, effective action in an emergency. Each State<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 57
must maintain an organization to handle health emergencies, establish coordinating committees and<br />
emergency animal health technical groups, define strategies and plans of action, and, when<br />
necessary, carry out the appropriate control measures within a timeframe compatible with a state of<br />
emergency [4, 7].<br />
Santa Catarina’s contingency plan requires each municipality to have a local operational plan that<br />
lists the names and contact information for all entities involved in emergency response. These<br />
include local police officials and mayors as well as truck washing terminals and technical<br />
responders. The emergency plan is triggered by an official declaration of sanitary emergency at the<br />
State level [11, 16].<br />
The 2008 site visit team reviewed local emergency operational plans while visiting the LVUs. These<br />
plans were up to date and included a high level of detail such as assignment of specific individuals to<br />
the various emergency functions. The local contingency plan is not specific to a particular disease,<br />
but is designed to be applied to any animal disease emergency [11].<br />
CIDASC has held sanitary emergency training sessions for professionals working in the official<br />
veterinary service. Recently, CIDASC trained 30 veterinarians in the management of emergencies.<br />
CIDASC also held two simulations, with the participation of all sectors, institutions and authorities<br />
involved in an emergency response [4].<br />
Animal owners, veterinarians, transporters, and members of the public are required by law to notify<br />
the LVU upon suspicion of a notifiable disease in any livestock. Penalties for noncompliance can<br />
include significant fines and/or legal actions. The official service is required by law to respond to<br />
reports of disease suspicion within 12 hours. All official veterinarians have been trained in carrying<br />
out this response [4]. If the LVU confirms a probable outbreak by clinical observation, the central<br />
offices of the affected State, the SFA and the DSA in Brasilia must be informed immediately. If the<br />
suspected case occurs in an area bordering another country, the local unit of the neighboring country<br />
must also be informed [5, 7].<br />
A vesicular disease suspicion kit, which is available to all LVUs through the regional office, is taken<br />
to the suspect holding by the official services veterinarian. This kit includes equipment for animal<br />
restraint, sample collection, and sanitation as well as disposable clothing and forms to collect<br />
information. The kit also includes a disease response manual which lists technical procedures and<br />
required reporting hierarchy.<br />
The 2008 site visit team reviewed the emergency response kit at the Chapeco regional office. The<br />
team found the kit to be extremely well stocked. It included laboratory submission materials and<br />
forms, protective clothing, cleaning and disinfection materials, and information on appropriate steps<br />
in the response, among other items [11].<br />
Once the LVU clinically confirms a notifiable disease, the involved holding and others in close<br />
proximity are quarantined and all animal movement is prohibited. Unauthorized movement of<br />
people and vehicles onto and off the holding is also prohibited. Officials collect samples for<br />
laboratory analysis and start an epidemiological investigation. At this point additional official<br />
veterinary teams are called on to conduct clinical and serologic surveillance around the suspected<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 58
holding and begin tracing animal movement on and off the premises during the 60 days prior to the<br />
likely beginning of the sanitary problem (30 days for CSF) [4, 7].<br />
Following laboratory confirmation, the LVU declares a state of sanitary emergency and recruits the<br />
civilian defense and military forces to the effort. In addition, other States, neighboring countries,<br />
trading partners, and international organizations are notified of the outbreak [19].<br />
Upon confirmation of disease the trace investigation is expanded to include the transit of people,<br />
transportation of products, fairs, abattoirs, and buyers who, before the imposition of the restrictions,<br />
had been in contact with the infected establishment. All professionals who work with animals inside<br />
the infected zone are informed of the occurrence of disease and are required to provide the official<br />
veterinary service with a list of all breeding establishments visited during the last 7 days [3].<br />
Ongoing sanitary emergency actions also include defining an emergency area around the affected<br />
holding at least 25 km in radius, restricting the transport of animals, animal products, and byproducts<br />
in the emergency area (as well as those related commercially to the affected holding), and banning<br />
agricultural and livestock events (shows, markets, auctions, and similar events) in the emergency<br />
area. The emergency area is subdivided into three areas, which are, in order of decreasing severity,<br />
the infected area, the surveillance area, and a buffer or protection area [4].<br />
The infected area includes the affected holding plus all other holdings within a minimum radius of<br />
3 km from the outbreaks. Within this area the movement of animals, people, and vehicles onto and<br />
off holdings is prohibited. Sick and contact animals must be destroyed (using compensation funds),<br />
and all places where the sick and contact animals had been held must be cleaned and disinfected [4].<br />
The surveillance area includes all holdings located within 7 km of the infected area. Animal<br />
movements are banned within this area, although animals may be slaughtered for internal<br />
consumption only (i.e., in slaughterhouses located within the surveillance zone itself) following<br />
approved biosecurity measures. Slaughter, when authorized, must be supervised by the official<br />
veterinarian and the meat boned with the bones incinerated. All susceptible animals must receive a<br />
clinical inspection, and surveillance and monitoring of this population must be constant.<br />
Surveillance must include serological evaluation of all susceptible animals within the infected zone<br />
[4].<br />
The buffer area surrounds the infected and surveillance areas and extends 15 km beyond the outer<br />
limits of the surveillance area. Measures taken within this zone include restrictions on animal<br />
transport, slaughter of animals for internal consumption only (in local abattoirs) as above, and<br />
ongoing surveillance, including clinical inspection of susceptible animals [4].<br />
Cleaning and disinfection of affected premises starts with removal of any excess organic matter.<br />
The area is then cleaned with water under pressure. All the material collected during this stage,<br />
including food, excreta, and effluents, must be destroyed (buried or incinerated). The facilities are<br />
washed again with detergents, followed by a preliminary disinfection after the facilities and the<br />
waste-collecting gutters have dried. The process is repeated as many times as the official service<br />
deems necessary. Machinery, equipment, and materials used to end the outbreak are also disinfected<br />
[3].<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 59
The minimum period required before restocking with sentinel animals after disinfection is 30 days<br />
for <strong>FMD</strong> and 10 days for CSF. Sentinel animals (young, weaned, unvaccinated animals) are<br />
introduced to the holding and held there for at least 30 days. The sentinel animals undergo serologic<br />
testing on introduction and at 15 days and 30 days after introduction. They are also subjected to<br />
weekly clinical evaluation, including measurement of body temperature. If both clinical exams and<br />
laboratory testing yield negative results at the end of the 30-day period, the facility may gradually<br />
carry out a controlled repopulation, under the supervision of the official veterinary service. If any of<br />
the sentinel animals test positive on serologic evaluation, all other animals are killed and the process<br />
starts again. The contingency measures applied in protection and surveillance zones are maintained<br />
until the property has been determined to be free of disease [3, 4].<br />
In 2005, Santa Catarina reported and investigated 83 notifications of reportable disease suspicions in<br />
holdings with <strong>FMD</strong>-susceptible animals. The State investigated 30 notifications for vesicular<br />
disease, 13 of which were due to trauma and 17 of which were due to diverse intoxications. In 2006,<br />
Santa Catarina reported and investigated 201 notifications of reportable disease suspicions in<br />
holdings with <strong>FMD</strong>-susceptible animals, 81 of which were investigated as vesicular disease<br />
suspicions. These were all found to be unfounded, with 41 due to traumatic injuries and 40 due to<br />
intoxication[4].<br />
Santa Catarina did not report any suspected cases of CSF in 2005 and 2006; however three suspected<br />
cases were reported in 2007. All of these were investigated and subsequently determined to be<br />
negative for CSF [3].<br />
Conclusions:<br />
<strong>Brazil</strong> has effective disease control and response programs for <strong>FMD</strong> and other notifiable ruminant<br />
and swine diseases. Santa Catarina has developed specific contingency plans for immediate action<br />
in any emergency situation. The State handles animal health emergencies, establishes coordinating<br />
committees and emergency animal health technical groups, defines strategies and plans of action,<br />
and, when necessary, carries out the appropriate control measures within a timeframe compatible<br />
with a state of emergency. Quarantine and movement restriction decisions are made by State<br />
officials with input from Federal authorities. There are also systems for notification and training that<br />
ensure emergency preparedness and response with a legal framework to authorize needed actions.<br />
APHIS concludes CIDASC has the capabilities to respond rapidly and effectively to an animal<br />
disease outbreak and limit the spread of the disease should an outbreak occur.<br />
Release Assessment Conclusions<br />
APHIS identified risk factors associated with importing <strong>FMD</strong>-susceptible species or their products to<br />
the United States from Santa Catarina. APHIS discussed these risk factors in the context of the<br />
potential for counterbalancing circumstances or applying appropriate risk mitigations to reduce the<br />
risk of introducing and establishing <strong>FMD</strong> or other swine notifiable diseases under evaluation in the<br />
United States. The risk mitigation procedures, which will be defined in the proposed rule, include<br />
various forms of verification and inspection to which APHIS will propose that MAPA certify to<br />
provide confidence that susceptible animals and their products meet acceptable export criteria.<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 60
Likelihood of the introduction of notifiable diseases into Santa Catarina<br />
<strong>Risk</strong> Factor<br />
1. <strong>FMD</strong> is endemic in some South American countries. CSF outbreaks have been detected in<br />
northern <strong>Brazil</strong>, in States located within the CSF-affected area, as recently as 2008. The <strong>FMD</strong> or<br />
CSF viruses could be reintroduced into Santa Catarina from adjacent affected areas. Consequently,<br />
there is a risk that susceptible species or products from such species bound for the United States<br />
could originate from or be commingled with animals or animal products from affected neighboring<br />
areas.<br />
In contrast, ASF and SVD are not present in South America. SVD has never been reported in the<br />
countries closest to Santa Catarina (Argentina, Paraguay, and Uruguay), nor has it been reported in<br />
<strong>Brazil</strong>. ASF has been reported in <strong>Brazil</strong>; however the last case occurred over 20 years ago.<br />
Discussion<br />
Santa Catarina authorities allow <strong>FMD</strong>-susceptible species to enter the State from other <strong>Brazil</strong>ian<br />
States as long as the animals are not vaccinated against <strong>FMD</strong>, the risk of introducing such animals is<br />
considered acceptable, and the destination and origination premises are suitable for quarantine<br />
purposes. Additionally, Santa Catarina has requirements in place, including serological testing, for<br />
susceptible animals (such as sheep, goats, and pigs) entering Santa Catarina from other States.<br />
Matured, deboned fresh beef is imported into Santa Catarina from other areas of <strong>Brazil</strong> for local<br />
consumption, since beef is not produced in sufficient quantities for local demand. This meat has a<br />
low risk of introducing <strong>FMD</strong> into Santa Catarina since it must go through a maturation process that<br />
kills the <strong>FMD</strong> virus.<br />
Swine entering Santa Catarina must originate from countries considered free of ASF, SVD, and<br />
CSF, as well as other swine diseases. The animals are also quarantined and may be tested for swine<br />
diseases both before and after import. Live swine may be imported from areas not considered free of<br />
CSF within <strong>Brazil</strong> if they are destined for immediate slaughter, but only under permit from MAPA.<br />
This comprises a minority of the pigs slaughtered in Santa Catarina.<br />
Mitigations<br />
Based on site visit observations, APHIS considers that Santa Catarina’s veterinary officials have<br />
adequate controls at the ports of entry (including airports) to mitigate risk for commercial and legal<br />
importation. Santa Catarina prohibits the importation of susceptible animals and animal products<br />
from areas considered affected by <strong>FMD</strong>, CSF, SVD, and ASF. In addition, Santa Catarina has<br />
stringent requirements in place, including serological testing, for importing animals from other<br />
States susceptible to the diseases under evaluation. Therefore, APHIS concludes that it is unlikely<br />
that <strong>FMD</strong> or other diseases of concern will be introduced through legal importation.<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 61
To ensure compliance with the appropriate controls for <strong>FMD</strong>, APHIS will propose in its rule that<br />
MAPA certify that <strong>FMD</strong>-susceptible animals and products did not originate from and were not<br />
commingled with animals or products from areas APHIS considers to be <strong>FMD</strong> affected.<br />
Specifically, APHIS will require the following certifications for beef or pork products exported to<br />
the United States from Santa Catarina:<br />
The beef or pork comes from animals that have been born, raised, and slaughtered in Santa<br />
Catarina.<br />
The beef or pork comes from animals that originated on premises where <strong>FMD</strong> has not been<br />
present during the lifetime of any of the animals slaughtered.<br />
<strong>Risk</strong> Factor<br />
2. There is a potential risk from illegal introduction of affected animals or animal products from<br />
affected regions. Santa Catarina contains several inspection posts in internal and external border<br />
areas. Even where there are barriers or checkpoints, people and animal products may cross both<br />
domestic and international borders illegally, particularly by passenger car. This increases the<br />
potential for the viruses under evaluation to cross the border.<br />
Mitigations<br />
APHIS evaluated Santa Catarina’s controls for animals moving into the State, as well as its<br />
biosecurity procedures and quarantine procedures, and concluded that they sufficiently mitigated the<br />
risk of illegal importations from affected regions.<br />
<strong>Risk</strong> Factor<br />
3. If <strong>FMD</strong> or the swine diseases under evaluation were to be reintroduced into Santa Catarina,<br />
disease might be spread through animals scavenging unmonitored garbage dumps.<br />
Mitigation<br />
<strong>Brazil</strong>ian laws prohibit the feeding of untreated garbage to animals, while Santa Catarina prohibits<br />
garbage feeding regardless of treatment. These laws are enforced effectively, so that animal garbage<br />
feeding is unlikely to occur in Santa Catarina.<br />
Release Assessment – Conclusion<br />
Based on evaluation of the 11 factors as well as observations from the site visits, APHIS considers<br />
that Santa Catarina possesses the detection capabilities, reporting systems, and emergency response<br />
systems necessary to combat <strong>FMD</strong>, CSF, SVD, and ASF.<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 62
Exposure Assessment<br />
An exposure assessment as defined by OIE describes the biological pathway(s) necessary for<br />
exposure of animals and humans in an importing country to the hazards of a given risk source, and<br />
estimates the probability of the exposure(s) occurring [20]. APHIS’ regulatory authority is limited<br />
to animal health, however, so its evaluation focuses on potential risks to animals. APHIS considers<br />
that domestic livestock are most likely to be exposed to <strong>FMD</strong>, CSF, SVD, and ASF viruses through<br />
feeding contaminated food waste to swine [21]. Other exposure pathways are more direct and<br />
include contact with imported infected live animals or contact with infected genetic material.<br />
Waste feeding to susceptible swine<br />
The likelihood of exposure of susceptible species to virus-infected meat was evaluated in previous<br />
APHIS studies. In 1995, APHIS conducted a pathway analysis to estimate the likelihood of<br />
exposing swine to infected waste. The analysis included two pathways for exposure of swine to<br />
contaminated waste: Exposure associated with illegal household imports, and exposure associated<br />
with legal imports [22]. The latter is the exposure pathway applicable to meat or meat products<br />
imported from Santa Catarina. With 95 percent confidence, APHIS estimated that 0.023 percent or<br />
less of plate and manufacturing waste would be inadequately processed prior to feeding to swine.<br />
Based on this fraction, less than 1 part in 4,300 (reciprocal of 0.023 percent) of imported meat is<br />
likely to be fed to swine as inadequately cooked waste [22].<br />
APHIS conducted a survey in 2001 of the U.S. swine waste-feeding sector to update a similar study<br />
done in 1994 [23]. Based on this survey, APHIS estimated that the proportion of plate and<br />
manufacturing waste fed to swine diminished by about 50 percent between 1994 and 2001 due to a<br />
significant decrease in the number of waste-feeding premises. The study also found that:<br />
1. Several additional States prohibited feeding food wastes to swine.<br />
2. The number of waste-feeding premises in the continental United States decreased by 40.5<br />
percent from 1994 to 2001, and in Hawaii and Puerto Rico decreased by 37.5 percent and<br />
52.3 percent, respectively.<br />
3. Institutions and restaurants provide nearly 90 percent of all plate waste fed to swine.<br />
APHIS considers that prohibiting feeding unprocessed plate waste to swine has further contributed<br />
to the reduction of swine waste-feeding. Waste-feeding operations must be licensed and inspected<br />
regularly by USDA inspectors under 9 CFR 166. The licensing process requires that producers<br />
adequately cook the waste fed to swine using methods designed to reduce the probability of survival<br />
of foreign animal disease agents.<br />
Based on the 1995 estimate that a very small proportion of food waste is inadequately processed<br />
prior to feeding to swine, and the substantial reduction in waste-feeding operations in recent years,<br />
APHIS concludes that the likelihood of exposure of susceptible swine to <strong>FMD</strong>, CSF, SVD, or ASF<br />
viruses through inadequately processed food waste is low.<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 63
Imported live animals<br />
The likelihood of exposure of susceptible species to infected live animals was evaluated by briefly<br />
reviewing virus persistence and shedding in live swine and ruminants, as well as standard import<br />
requirements for these species. The exposure assessment focuses on breeding animals because of<br />
high transportation costs for export of other live animals (such as feeder pigs or cattle) to the United<br />
States from <strong>Brazil</strong>. APHIS considers exposure of susceptible U.S. animals to illegally imported<br />
infected live animals from Santa Catarina to be highly unlikely.<br />
The survival period of CSF virus within live swine ranges from 1 week to greater than 6 months,<br />
depending on various host-pathogen factors. Similarly, up to 50 percent of ruminant animals may<br />
become carriers of the <strong>FMD</strong> virus. The maximum reported duration of the carrier state is 3.5 years<br />
in cattle, 9 months in sheep, and 4 months in goats. Carrier virus is fully infectious, and<br />
consequently the carrier state is associated with at least a theoretical risk of introducing <strong>FMD</strong> into a<br />
susceptible population. ASF may also exhibit a chronic carrier state, while SVD virus is not known<br />
to cause persistent infection. A large percentage of infections are subclinical and therefore may<br />
remain undetected without diagnostic testing prior to export [24].<br />
Consequently, APHIS considers this potential pathway to pose a high risk for disease introduction if<br />
unmitigated. However, current U.S. regulations require certification that ruminants and swine have<br />
been kept in a region entirely free of <strong>FMD</strong>, CSF, SVD, and ASF for 60 days prior to export (9 CFR<br />
93.405 and 9 CFR 93.505). They also require a minimum quarantine of 30 days for most imported<br />
ruminants (9 CFR 93.411) and 15 days for all imported swine (9 CFR 93.510). These requirements<br />
serve to partially mitigate the risk of exposure by increasing the likelihood of detection in exported<br />
animals.<br />
Based on the results of the release assessment, APHIS considers the likelihood that animals infected<br />
with <strong>FMD</strong>, CSF, SVD, or ASF virus will enter the United States from Santa Catarina to be very low.<br />
The resultant likelihood of animal exposure to <strong>FMD</strong>, SVD, and ASF viruses via this pathway is<br />
similarly low.<br />
Imported genetic material<br />
Genetic materials have been implicated in the introduction of foreign animal disease into susceptible<br />
populations, as well as the spread of established disease epidemics over considerable distances. For<br />
example, two semen collection centers became infected during the course of the 1997-1998 CSF<br />
epidemic in the Netherlands. Potentially contaminated semen was distributed to 1,680 swine herds<br />
over the course of 5 weeks, during which the disease remained undetected in the donor boars.<br />
Although investigators concluded that only 36 farms had been infected through artificial<br />
insemination, all suspect farms were subject to quarantine and testing, resulting in a tremendous<br />
expenditure of resources [25].<br />
Survival of CSF virus in semen has been estimated in experimental studies to be 12 to 72 hours at<br />
20C, but ranges from 1 month to several years at 4C or below [26]. Survival in embryos and ova is<br />
unknown [26, 27]. <strong>FMD</strong> virus may be present in semen up to 4 days before clinical signs become<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 64
apparent [28]. Survival of both SVD and ASF viruses in genetic material is possible but is not<br />
considered to be a primary mode of transmission [29, 30].<br />
Based on the extended period of survival of CSF and <strong>FMD</strong> viruses in frozen semen, APHIS<br />
considers the likelihood of exposure of susceptible animals to these viruses in infected semen, if it<br />
were to be imported into the United States, to be high if unmitigated. However, based on the results<br />
of the release assessment, APHIS considers the likelihood of release of CSF or <strong>FMD</strong> viruses via<br />
infected semen from Santa Catarina to be very low. The likelihood of exposure of domestic<br />
livestock would be similarly low.<br />
Consequence Assessment<br />
A consequence assessment describes the biologic and economic consequences of introducing the<br />
hazards under consideration into the United States. This consequence assessment addresses both<br />
direct and indirect consequences, as recommended by the OIE [20].<br />
The magnitude of the biologic and economic consequences following an introduction of <strong>FMD</strong>, CSF,<br />
SVD, or ASF virus would depend on the location of the introduction, the virus serotype introduced,<br />
the rate of virus spread and whether environmental conditions at the introduction site might facilitate<br />
this spread, the site’s ability to detect the disease rapidly, livestock demographics and movement<br />
patterns, and the ease of employing eradication procedures. In addition, depending on the extent of<br />
export of livestock and animal products, trade restrictions imposed by trading partners may result in<br />
severe economic consequences [31].<br />
Direct consequences include effects of the disease on animal health and subsequent production<br />
losses, the total costs of control and eradication, the effect on the environment, and public health<br />
consequences. Indirect consequences include effects on international trade and associated domestic<br />
consequences.<br />
Animal health consequences<br />
<strong>FMD</strong><br />
<strong>FMD</strong> causes significant distress and suffering to animals regardless of the size and sophistication of<br />
their livestock unit. Very high mortality rates in young animals can occur, particularly among pigs<br />
and sheep. Mortality in older animals occurs less frequently but may be significant with certain<br />
virus strains [24, 32, 33].<br />
<strong>FMD</strong> also causes significant losses in the production capacity of affected animals. Productivity<br />
losses of 10 percent to 20 percent are reported in <strong>FMD</strong>-infected livestock if the disease is allowed to<br />
run its course. In addition, <strong>FMD</strong> can cause a reduction in the growth rate of animals raised for meat.<br />
The comparatively greater severity of <strong>FMD</strong> in pigs would imply at least similar losses to those<br />
described for cattle [31, 34].<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 65
CSF<br />
CSF has acute and chronic courses. The severity of the disease depends largely on the age of the<br />
animal and the virulence of the viral strain, with young animals usually more severely affected than<br />
older animals. In older breeding pigs the course of infection is often mild or even subclinical,<br />
whereas mortality rates may reach 90 percent in young pigs [35]. Low virulence strains may<br />
manifest primarily as poor reproductive performance and birth of piglets with neurologic defects<br />
[35].<br />
SVD<br />
SVD is typically a transient vesicular disease of pigs. The virus causes essentially no mortality, and<br />
infected pigs generally recover within 1 week (on occasion, recovery may take up to 3 weeks).<br />
Some strains produce only mild clinical symptoms or are asymptomatic. Morbidity rates may be<br />
low throughout a whole herd but high in certain pens [29].<br />
ASF<br />
ASF is a highly contagious hemorrhagic disease of pigs. All age groups are equally susceptible.<br />
With high virulence forms of the virus, ASF is characterized by high fever, loss of appetite,<br />
hemorrhages in the skin and internal organs, and death within 2 to 10 days on average. Herd<br />
mortality rates may be as high as 100 percent [30].<br />
Economic consequences<br />
The overall cost of control and eradication depends on the mitigation or policy options chosen to<br />
control and eradicate the disease. Potential costs include costs for disease control measures such as<br />
imposing quarantine measures and movement controls, direct costs related to stamping out of<br />
affected herds, indemnity payments, vaccination costs, and costs for surveillance and laboratory<br />
testing. For disease-free countries like the United States that have a substantial export market for<br />
livestock and livestock products, the preferred option for control and eradication has traditionally<br />
been to stamp out infected herds without the use of vaccine.<br />
The U.S. policy for most significant foreign animal disease emergencies is to follow strict quarantine<br />
measures and stamp out infected and contact herds. Officials also assess the need for strategic<br />
vaccination, and carry out vaccination if necessary. Available data do not allow quantification of the<br />
number of herds or farms that could be infected if one of the diseases under evaluation were<br />
introduced into the United States. Nevertheless, the cost of control, eradication, and compensation is<br />
likely to be significant.<br />
<strong>FMD</strong><br />
A few studies have estimated the potential consequences of an <strong>FMD</strong> outbreak in the United States.<br />
Bates et al (2003) used results from an <strong>FMD</strong> simulation model to estimate the direct costs associated<br />
with indemnity, slaughter, cleaning, and disinfecting livestock premises for various vaccination and<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 66
eradication strategies to control transmission of <strong>FMD</strong>V in a cattle population of 2,238 herds and 5<br />
sale yards located in 3 counties in California. The study found that mean herd indemnity payments<br />
were $2.6 million and $110,359 for dairy and non-dairy herds, respectively. Cleaning and<br />
disinfection costs ranged from $18,062 to $60,205 per herd. The mean vaccination cost was $2,960<br />
per herd and the total eradication cost ranged from $61 million to $551 million, depending on<br />
eradication strategy [36].<br />
McCauley et al (1979) conducted a comprehensive study to assess the potential economic impact of<br />
<strong>FMD</strong> in the whole of the United States. The study estimated the direct costs (control and eradication<br />
program costs) and increased costs borne by consumers of <strong>FMD</strong> introduction over a 15-year period<br />
(1976-1990). Using the Consumer Price Index to update to 2001, the estimated total cost of a strict<br />
quarantine and slaughter policy was $34.4 million [31].<br />
CSF<br />
Since there have been no CSF outbreaks in the United States from which economic estimates can be<br />
derived, estimates of economic effects in other countries are provided as illustrations.<br />
Saatkamp et al (2000) reviewed the economic aspects of control of small and large CSF outbreaks in<br />
the European Union (EU) from 1990 to 1997. For the largest outbreak, involving 429 herds over 14<br />
months, the cost of removing affected swine was 426.9 million Euros, slaughter for welfare purposes<br />
cost 1.2 billion Euros, and program operational costs were 134.3 million Euros. Overall, the<br />
outbreak cost pig producers 712.4 million Euros, the national government 230.5 million Euros, and<br />
the EU 807.8 million Euros. Approximately 10 million pigs were destroyed during the outbreak,<br />
primarily for welfare reasons (being in overcrowded conditions, or being overweight) [37]. The total<br />
cost of smaller outbreaks ranged from 10.9 million Euros (8 affected herds over 2 months) to 208.7<br />
million Euros (113 affected herds over 10 months) [38].<br />
Garner et al (2001) estimated the potential economic impact of CSF on the Australian pig industry<br />
using a stochastic modeling process. The model estimated a loss in gross income of 28 percent to 37<br />
percent for the pig industry in the affected region, and a 9 percent to 11 percent loss in gross income<br />
for the national pig industry [39].<br />
SVD<br />
Little information exists on the cost of control and eradication of SVD in a previously free region.<br />
SVD virus generally does not spread as quickly as CSF virus, even on infected premises. Spread<br />
from one pen to another may not occur in the absence of a common open drainage system or of<br />
frequent movement of pigs between pens. However, an SVD outbreak may not be detected for<br />
weeks or even months due to the frequently mild nature of the disease, allowing ample time for it to<br />
spread to other swine establishments. In addition, the virus is extraordinarily stable in the<br />
environment, which could lead to disease recurrence on previously infected farms [40]. In the<br />
absence of specific data on the cost of control and eradication, APHIS assumes a baseline cost<br />
similar to that of a small- to medium-sized CSF outbreak (see above).<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 67
ASF<br />
As with SVD, there is little information on the cost of control and eradication of ASF in a previously<br />
free region. In the absence of specific data on the cost of control and eradication, APHIS assumes a<br />
baseline cost similar to that of a small- to medium-sized CSF outbreak (see above).<br />
While these examples estimate a more severe outcome of an outbreak, the consequences could be<br />
lessened if the outbreak was detected earlier and appropriate controls implemented to quickly<br />
eradicate the disease.<br />
Environmental consequences<br />
Environmental consequences resulting from introduction of <strong>FMD</strong>, CSF, SVD, or ASF would<br />
primarily occur from disposal of carcasses due to death from disease or depopulation of herds, as<br />
well as disposal of contaminated bedding and manure. The methods of disposal employed in<br />
response to an outbreak would affect the environment differently. Disposal of contaminated<br />
materials could potentially affect air, water, and soil quality, as well as potentially releasing live<br />
virus into the environment.<br />
Disposal options previously employed in other countries in response to large-scale animal disease<br />
outbreaks include rendering, burial, and incineration. Factors influencing the decision as to which<br />
methods of disposal to use include the volume of contaminated material (dependent on the number<br />
of animals affected), geographic features (such as soil and surface water) of the areas where<br />
outbreaks occur, other environmental considerations such as weather and ambient temperature, and<br />
available emergency resources such as funds, equipment, and personnel. The environmental<br />
consequences of an outbreak of one of these diseases in the United States could vary from marginal<br />
to extreme depending on factors related to disposal of contaminated carcasses and materials.<br />
Public health consequences<br />
Although APHIS’ regulatory authority does not cover public health consequences, this assessment<br />
briefly addresses the issue. Direct public health consequences are insubstantial because the<br />
occurrence of <strong>FMD</strong>, CSF, SVD, or ASF virus in humans is quite rare. In fact, the number of cases<br />
reported is so small compared with the number of persons exposed to these viruses that the World<br />
Health Organization generally does not consider <strong>FMD</strong>, CSF, SVD, or ASF to be threats to humans.<br />
Perhaps more importantly, a substantial foreign animal disease outbreak can result in severe<br />
psychosocial effects on farmers and farming communities. Farmers and their families can suffer<br />
from grief over losing animals, in some cases bloodlines kept over many generations, as well as loss<br />
of control over their lives due to movement restrictions, disruptions in community life, and shortand<br />
long-term financial stress.<br />
Indirect consequences<br />
In addition to the direct costs of <strong>FMD</strong>, CSF, SVD, or ASF introduction, the effect on international<br />
trade and related domestic consequences must also be considered. Export losses caused by trade<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 68
partners’ restrictions on animals and products susceptible to the diseases under evaluation could run<br />
into billions of U.S. dollars. The value of U.S. exports of pork and pork products that would be<br />
immediately lost if an outbreak of one of these diseases occurred was an estimated $1.3 billion in<br />
2003 [41]. Similarly, the value of U.S. exports of beef products that would also be lost in an <strong>FMD</strong><br />
outbreak was over $3 billion in 2001. Since the United States exports only small amounts of lamb<br />
and mutton, economic losses associated with these commodities are not likely to be significant<br />
compared to cattle and swine.<br />
The effect of an outbreak of a foreign animal disease on rural and regional economic viability,<br />
including businesses reliant on livestock revenue, could also be substantial. For example, Paarlberg<br />
et al. (2002) conducted a study to estimate the potential revenue impact of an <strong>FMD</strong> outbreak in the<br />
United States similar to the one that occurred in the United Kingdom in 2001. This study estimated<br />
the gross revenue losses for the animal sector as follows: live cattle (17 percent), beef (20 percent),<br />
milk (16 percent), live swine (34 percent), pork (24 percent), live sheep and lambs (14 percent), and<br />
sheep and lamb meat (10 percent) [42].<br />
Indirect economic losses to U.S. firms that support export markets for live animals and animal<br />
products could also be substantial. For example, such firms could lose at least $2.5 billion annually<br />
if ruminant export markets were lost. More than 33,000 full-time U.S. jobs, accounting for almost<br />
$1 billion in wages annually, could be jeopardized by loss of these markets. In the longer term, if<br />
trade restrictions persisted and alternative export markets did not develop, the U.S. ruminant<br />
production sector could contract, allowing other supplying countries to establish trade relationships<br />
in the absence of U.S. supply. Losses due to restrictions on live swine, pork, and pork products<br />
could also be significant [43].<br />
<strong>Risk</strong> Estimation<br />
<strong>Risk</strong> estimation consists of integrating the results from the release assessment, exposure assessment,<br />
and consequence assessment to produce overall measures of risk associated with the hazards<br />
identified at the outset. Thus, risk estimation takes into account the whole risk pathway from the<br />
hazard identified to the unwanted event [20].<br />
APHIS concludes from the assessment that the surveillance, prevention, and control measures<br />
implemented by Santa Catarina are sufficient to minimize the likelihood of introducing <strong>FMD</strong>, CSF,<br />
SVD, and ASF into the United States via imports of <strong>FMD</strong>-susceptible species or products from such<br />
species. Although consequences of an <strong>FMD</strong>, CSF, SVD, or ASF outbreak are potentially<br />
substantial, the likelihood of an outbreak occurring via exposure of the domestic livestock<br />
population to pork or pork products imported from Santa Catarina is very low.<br />
The consequences of a <strong>FMD</strong> outbreak in the United States would be extremely high. The major<br />
economic consequence of importing <strong>FMD</strong> would be export trade losses. The sum of the consumer<br />
impacts, direct costs and trade losses over a 15-year period would be between $37 billion and $44<br />
billion (in 2001 dollars), depending on the magnitude of the outbreak and eradication strategy.<br />
Although the consequences are significant, the results of both the release and exposure assessment<br />
indicate that the likelihood of introduction and establishment of <strong>FMD</strong> is low.<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 69
In summary, although the consequences of a <strong>FMD</strong> outbreak in the United States would be very high,<br />
the findings of the release and exposure assessments lead APHIS to consider the risk of <strong>FMD</strong>infected<br />
animals or products entering the United States from Santa Catarina and exposing U.S.<br />
livestock to the disease to be low.<br />

Etiologic Agent<br />
Family Picornaviridae, Genus Aphthovirus, types O, A, C, SAT1, SAT2, SAT3, and Asia 1.<br />
Status in the United States<br />
<strong>FMD</strong> virus was eradicated from the United States in 1929.<br />
Epidemiology<br />
<strong>FMD</strong> is a highly communicable disease of cloven-hoofed animals caused by an Aphthovirus of the<br />
family Picornaviridae. <strong>FMD</strong> has seven immunologically distinct serotypes (O, A, C, SAT1, SAT2,<br />
SAT3, and Asia 1). The O, A, and C serotypes have historically been found in South America [44].<br />
Research indicates that one serotype does not confer protective immunity against the other six; thus<br />
a disease outbreak can be caused by one serotype or a combination of serotypes [45].<br />
<strong>FMD</strong> virus serotype O (PanAsia strain) has been isolated in over 60 percent of positive samples<br />
received by the World Reference Laboratory for <strong>FMD</strong> in the United Kingdom (Institute for Animal<br />
Health, Pirbright Laboratory). Along with being the most prevalent type O strain, the PanAsia strain<br />
is also the most widely distributed, causing <strong>FMD</strong> outbreaks in many parts of Africa, Asia, and South<br />
America as well as in Europe since 1998. This virus strain can infect a wide range of species<br />
including cattle, water buffalo, pigs, sheep, goats, and gazelles.<br />
<strong>FMD</strong> virus can be transmitted by direct or indirect contact or aerosol. Fomites (items such as feed,<br />
drinking water, equipment, animal products, human clothing, transportation vehicles, rodents, stray<br />
dogs, wild animals, and birds) can transmit <strong>FMD</strong> over long distances. The five main elements that<br />
influence the extent of <strong>FMD</strong> spread are:<br />
The quantity of virus released<br />
The means by which the virus enters the environment<br />
The ability of the virus to survive outside the animal body<br />
The quantities of virus required to initiate infection at primary infection sites<br />
The period of time the virus remains undetected [46, 47]<br />
The incubation period of the <strong>FMD</strong> virus is 2 to 14 days in cattle, depending on the viral strain and<br />
dose and the level of susceptibility of the animal [48]. Morbidity in unvaccinated herds can be high,<br />
but mortality usually does not exceed 5 percent. If an outbreak occurs during the calving season,<br />
calf mortality can be considerable [49]. Young calves may even die before clinical signs appear,<br />
because the virus attacks the heart muscles [48].<br />
The respiratory tract is the usual route of infection in species other than pigs. Infection can also<br />
occur through abrasions of the skin or mucous membranes. In cattle and sheep, the earliest sites of<br />
virus infection and possibly replication appear to be in the mucosa and the lymphoid tissues of the<br />
pharynx. Following initial replication in the pharynx, the virus then enters the bloodstream.<br />
Viremia in cattle lasts for 3 to 5 days; as a result, the virus spreads throughout the body and<br />
establishes sites of secondary infection [50].<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 71
The usual route of infection in pigs is through ingestion of <strong>FMD</strong>-virus contaminated products, direct<br />
contact with infected animals, or occupation of heavily contaminated environments. The incubation<br />
period in pigs will vary with the strain, dose, and route of infection. Serotype O, which is highly<br />
virulent in pigs, can produce clinical signs within 18 to 24 hours, while pigs with low-level<br />
exposures may take up to 11 days to develop clinical signs. Pigs that recover from <strong>FMD</strong> infection<br />
do not become carriers, as was thought with ruminants [51].<br />
<strong>FMD</strong> virus localizes in various organs, tissues, body fluids, bone marrow, and lymph nodes [52].<br />
Viral replication may reach peak levels as early as 2 to 3 days after exposure. Virus titers differ in<br />
different organs or tissues. Some tissues, such as the tongue epithelium, have particularly high titers.<br />
Recent data indicate that the most viral amplification occurs in the stratified, cornified squamous<br />
epithelia of the skin and mouth (including the tongue). Although some viral replication also occurs<br />
in the epithelia of the pharynx, the amount of virus produced there is apparently much less than the<br />
amount produced in the skin and mouth during the acute phase of the disease. By comparison, the<br />
amount of virus (if any) produced in other organs like salivary glands, kidneys, liver, and lymph<br />
nodes is negligible [53, 54].<br />
Immunity to <strong>FMD</strong> is primarily mediated by circulating antibodies [55]. The host reaction, including<br />
antibody production, occurs from 3 to 4 days after exposure. In infected pigs, the virus is cleared<br />
within 3 to 4 weeks. In contrast, around 50 percent or more of cattle will develop a low-level<br />
persistent infection, localized to the pharynx [56-58]. According to Alexandersen (2002), a model<br />
for progression of infection starts with virus exposure, then accumulation of virus in the pharyngeal<br />
area, followed by the initial spread through regional lymph nodes, and then via the bloodstream to<br />
epithelial cells. Several cycles of viral amplification and spread follow[55].<br />
Clinical signs in cattle during acute infection include fever, profuse salivation, and mucopurulent<br />
nasal discharge. The disease is characterized by development of vesicles on the tongue, hard palate,<br />
dental pad, lips, muzzle, gum, coronary band, and interdigital spaces. Vesicles may develop on the<br />
teats. Affected animals lose condition rapidly, and there is a dramatic loss of milk production [48].<br />
The animal usually recovers by 14 days post infection provided no secondary infections occur [50].<br />
The most consistent clinical signs in pigs are lesions around the coronary bands and lameness, but<br />
fever may be inconsistent. Pigs may develop vesicles on the tongue and snout, but these may be less<br />
conspicuous than lesions seen in ruminants. The severity of clinical disease depends on the age of<br />
the infected pig. Adult swine may recover or become chronically lame while younger pigs,<br />
especially those less than 8 weeks of age, may die from acute myocarditis without developing other<br />
clinical signs [48, 57].<br />
Diagnosis of the disease relies heavily on recognizing clinical signs. In unvaccinated cattle and pigs,<br />
the clinical signs are obvious. However, in small ruminants the disease is often subclinical or is<br />
easily confused with other conditions. In addition, in endemic regions, clinical signs in partially<br />
immune cattle may be less obvious and could pass unnoticed [48, 57]. Virus isolation and serotype<br />
identification are necessary for confirmatory diagnosis. The clinical signs of <strong>FMD</strong> are similar to<br />
those seen in other vesicular diseases. Differential diagnosis of vesicular diseases includes vesicular<br />
stomatitis, mucosal disease of cattle, bluetongue, rinderpest, and <strong>FMD</strong>. Serological diagnostic tests<br />
include the complement-fixation test, virus neutralization test, and an enzyme-linked immunosorbent<br />
APHIS <strong>Evaluation</strong> of the Status of the <strong>Brazil</strong>ian State of Santa Catarina 72
assay test. Other diagnostic tests include one- or two-dimensional electrophoresis of the viral DNA,<br />
isoelectric focusing of the viral structural proteins, or nucleotide sequencing of the viral RNA[47].<br />
<strong>FMD</strong> virus is a relatively resilient virus. It can survive up to 15 weeks in feed, 4 weeks on cattle<br />
hair, and up to 103 days in wastewater. The survival of the virus in animal tissues is closely<br />
associated with the acidity of that tissue. For example, in muscular tissues the acidity of rigor<br />
mortis, which occurs naturally, inactivates the virus. The production of lactic acid in these tissues<br />
during maturation is considered the primary factor for inactivation [43]. An acid environment where<br />
the pH is less than 6.0 will destroy the virus quickly [43, 59]. Several studies showed that in tissues<br />
where no acidification occurs (e.g., lymph nodes, bone marrow, fat, and blood), the virus may<br />
survive for extended times in cured, uncured, and frozen meat [43, 60, 61]. Heating at 50° C [43]<br />
and up to 155° F [59] will inactivate the virus.<br />

Annex 2. Hazard Identification: Classical Swine Fever Virus<br />
CSF, also known as hog cholera, is a contagious and economically damaging viral disease of<br />
domestic swine and wild boar with worldwide distribution. It is caused by the CSF virus of the<br />
family Flaviviridae, genus Pestivirus [62]. CSF virus is quite hardy, being stable between pH 4 and<br />
10, and is also stable at low temperatures [63, 64]. The virus may remain viable even after carcass<br />
maturation, and is unlikely to be destroyed by transport or cold storage. Laboratory confirmation of<br />
infection, essential during an outbreak, is complicated by the close antigenic relationship of the CSF<br />
virus with bovine viral diarrhea virus and border disease virus [62].<br />
The incubation period for CSF is 2 to 14 days [28]. The virus multiplies in the epithelial crypts of<br />
the tonsils and may be carried to local lymph nodes and into the bloodstream for distribution<br />
throughout the body [65]. Blood and all tissues, secretions, and excretions of sick and dead animals<br />
are sources of infection [28]. CSF virus has been recovered from muscle and lymph nodes of<br />
infected pigs, and high titers of virus have been isolated from bone marrow [66]. The disease may<br />
also be introduced or spread via infected semen [67].<br />
CSF can spread in an epidemic form as well as establish enzootic infections in domestic swine and<br />
wild boar populations. Infection generally spreads directly from pig to pig, but products including<br />
fresh, frozen, or cured pork can remain infectious to other pigs by mouth [68]. Imported pig<br />
products are frequently implicated in the introduction of CSF virus into previously disease-free<br />
regions, primarily through the practice of swill feeding [69]. Dahle and Liess (1992) demonstrated<br />
that the oral infectious dose of CSF virus is very low [70]. Indirect transmission may occur via<br />
movement of people, wild animals, and inanimate objects such as live-haul trucks [71].<br />
The role of wild boar as a virus reservoir and possible source of infection for domestic swine is well<br />
known, and epidemiological links between CSF virus infection in wild boar and domestic swine<br />
have been reported repeatedly in recent years [72, 73]. In countries that are free of CSF in domestic<br />
swine, epidemics in wild boar are often started by feeding the animals infected human food waste<br />
(EC 1999). Abnormal mortality and sometimes obviously sick animals are the first indicators of<br />
CSF introduction into a wild boar population (EC 1999).<br />
Four distinct clinical forms of CSF have been described, including acute, chronic, congenital, and<br />
mild manifestations. The acute form involves a disease progression of 2 to 4 weeks and is<br />
characterized by high fever, generalized illness, hemorrhagic lesions, immunosuppression with<br />
secondary infections, and high mortality. The chronic form may last 30 to 90 days before death and<br />
usually involves older swine or congenitally infected piglets. Congenitally infected piglets may<br />
develop symptoms of chronic CSF within 3 to 6 months, or may never develop symptoms but<br />
continuously shed virus. Mild CSF is typically seen only in sows and may result from exposure to a<br />
low-virulent strain. Infected sows may show no overt clinical signs but continuously shed virus to<br />
their young and to other swine they contact [74, 75].<br />

Annex 3. Hazard Identification: Swine Vesicular Disease Virus<br />
SVD is a contagious and economically damaging disease of domestic swine and wild boar. The<br />
disease has historically been recorded in Hong Kong, Japan, and several European countries;<br />
however, in 2004 the disease was primarily limited to Italy and Portugal (OIE 2005a). The SVD<br />
virus belongs to the family Picornaviridae, genus Enterovirus [62]. SVD virus is particularly hardy,<br />
as it is resistant to pH changes between 2.5 and 12 and is very stable under cold conditions [76, 77].<br />
The virus is therefore unlikely to be destroyed by the postmortem decrease in muscle pH that<br />
accompanies carcass maturation. SVD virus is also resistant to fermentation and smoking. It may<br />
remain in hams for 180 days, sausages for over a year, and processed intestinal casings for over 2<br />
years [29].<br />
The incubation period for SVD is 2 to 7 days. The intestinal tract is the primary site of infection;<br />
however, all tissues contain virus during the viremic period. Blood and feces of sick animals, as<br />
well as epithelium from vesicles and vesicular fluid, are significant sources of virus. Although SVD<br />
virus does not appear to have a tropism for skeletal muscle cells, it is easily isolated from muscle<br />
tissue from infected animals after slaughter and bleeding out. SVD may be introduced into a herd by<br />
feeding garbage containing infected meat scraps, by introducing infected animals into a herd, or by<br />
contacting infected feces (e.g., an improperly cleaned truck). After the initial introduction the<br />
disease spreads through contact of susceptible pigs with infected pigs and infected feces.<br />
The clinical signs of SVD are easily confused with those of <strong>FMD</strong> and include fever, sudden<br />
lameness, and vesicles with subsequent erosions along the snout, feet, and teats. Morbidity rates<br />
may be low throughout a whole herd but high in certain pens. SVD causes essentially no mortality,<br />
and recovery usually occurs within 1 week (in some cases, up to 3 weeks). SVD infections seldom<br />
persist (Lin et al 2001); however, some strains produce only mild clinical symptoms or are<br />
asymptomatic, and are detected only through laboratory surveillance [29]. For example, a 2002<br />
outbreak of SVD in Italy involved subclinical infection in all but one of 10,312 affected pigs<br />
(Brocchio et al 2002).<br />

Annex 4. Hazard Identification: African Swine Fever Disease Virus<br />
African swine fever (ASF) is a highly contagious, frequently fatal, and economically damaging viral<br />
disease of pigs. As specified in 9 CFR 94.8, APHIS believes that ASF exists in all countries of<br />
Africa, as well as in <strong>Brazil</strong>, Cuba, Georgia, Haiti, Malta, and Sardinia, one of Italy’s islands. ASF<br />
has never been reported in the United States [78]. Natural hosts of ASF virus are members of the<br />
suidae family of mammals, including domestic and wild swine [30, 79].<br />
In sub-Saharan Africa, ASF is maintained in the wild through a life cycle including wild suidae and<br />
soft-bodied ticks (Ortnithodoros sp.)[80]. The disease is primarily spread into previously uninfected<br />
areas through feeding improperly cooked swill containing ASFV to domestic swine. The virus is<br />
generally spread among domestic pigs by direct or indirect contact [80]. The virus is present in all<br />
secretions and excretions, including blood and oral and nasal secretions, and may be spread through<br />
semen [79]. Virus is often shed before the onset of clinical signs in acute and subacute disease [81].<br />
The incubation period following exposure via direct contact is 5 to 19 days, while the incubation<br />
period following tick exposure may be fewer than 5 days. Depending on the virulence of the strain,<br />
ASF can manifest as percute, acute, subacute, chronic, or even inapparent disease. The peracute<br />
form generally causes sudden death. In the acute form, pigs display a multitude of clinical signs,<br />
ranging from cyanosis and dyspnea to diarrhea. Nearly all body systems are affected. Death<br />
generally follows in 7 to 10 days.<br />
The signs of subacute ASF are similar to those of the acute disease, but are less severe. Low virulent<br />
viral strains can cause inapparent, mild, or chronic infections. Abortion may be the only clinical<br />
sign, but intermittent fevers, emaciation, respiratory problems, swollen joints, skin lesions and<br />
potentially death may occur [80].<br />
The ASF virus is stable across a wide temperature and pH range [79]. The virus has been shown to<br />
survive in chilled or frozen pork for 104 days. The virus has also been shown to survive for at least<br />
some period at pHs ranging from 3.1 to 11.5. Pork generally reaches a pH of 5.4-5.5 following<br />
carcass maturation, but this varies depending on the specific carcass and the temperature. The virus<br />
can often survive processes such as curing and salting. Farez and Morley conducted a literature<br />
review and reported survival times ranging from 30 days in salami to 399 days in Parma ham [82].<br />

Annex 5. Epidemiologic Characteristics of Rinderpest<br />
Etiologic Agent<br />
Family Paramyxoviridae, Genus Morbillivirus<br />
Status in the United States<br />
The United States has been historically free from rinderpest.<br />
Distribution<br />
Historically the virus was widely distributed throughout Europe, Africa, Asia and West Asia, but<br />
never became established in either the Americas or Australia/New Zealand. Rinderpest is an OIE<br />
listed disease. [83] In Africa it has been eradicated from several countries and sub-regions, and is<br />
normally absent from the northern and southern parts of the continent. Rinderpest occurs in the<br />
Middle East and in southwestern and central Asia [84].<br />
Epidemiology<br />
Rinderpest is a highly fatal viral disease of domestic cattle, buffaloes and yaks. It also affects sheep,<br />
goats and some breeds of pigs (Asian pigs seem more susceptible than African and European pigs).<br />
Rinderpest can infect a large variety of wildlife species, including African buffaloes, eland, kudu,<br />
wilde-beest, various antelopes, bushpigs, warthog and giraffes but is rare among camelids [83, 84,<br />
85].<br />
Transmission of rinderpest can occur through direct or close indirect contacts. The usual route of<br />
infection is via the respiratory tract with an incubation period of generally 4 to 5 days following<br />
natural exposures but which may range from 3 to 15 days. Viral shedding begins 1-2 days before<br />
pyrexia in tears, nasal secretions, saliva, urine and feces and typically continues for 8 to 9 days after<br />
the onset of clinical signs. Blood and all tissues are infectious before the appearance of clinical<br />
signs.<br />
Rinderpest can take several clinical presentations; classic, peracute, subacute and atypical. There is<br />
no carrier state following infection. The classic form is characterized by a 2- to 3-day period of high<br />
fever, depression, anorexia, reduced rumination, increased respiratory and cardiac rate, congested<br />
mucus membranes, intense mucopurulent lachrymation and excessive salivation. Gastrointestinal<br />
signs appear when the fever drops with profuse hemorrhagic diarrhea. Dehydration, abdominal pain,<br />
abdominal respiration, weakness, recumbency and death generally occur within 8-12 days. In rare<br />
cases, clinical signs regress by day 10 and recovery occurs by day 20-25.<br />
The peracute form has no prodromal signs and is characterized by high fever (>40-42°C) and death.<br />
The peracute form occurs in highly susceptible young and newborn animals. The subacute form has<br />
a low mortality rate and a similar clinical presentation to the classic form. The atypical form is<br />
characterized by irregular pyrexia with mild or no diarrhea.<br />
Rinderpest virus is relatively resistant and is stable between pH 4.0 and 10.0 but is susceptible to<br />
most common disinfectants including lipid solvents. The virus remains viable for long periods in<br />
chilled or frozen tissues. Small amounts of rinderpest virus may survive relatively high<br />
temperatures—56°C (133°F) for 60 min or 60°C (140°F) for 30 min.<br />
