Exhibit 8, 100416 Brazil FMD Risk Evaluation - R-Calf

The minimum period required before restocking with sentinel animals after disinfection is 30 days
for FMD and 10 days for CSF. Sentinel animals (young, weaned, unvaccinated animals) are
introduced to the holding and held there for at least 30 days. The sentinel animals undergo serologic
testing on introduction and at 15 days and 30 days after introduction. They are also subjected to
weekly clinical evaluation, including measurement of body temperature. If both clinical exams and
laboratory testing yield negative results at the end of the 30-day period, the facility may gradually
carry out a controlled repopulation, under the supervision of the official veterinary service. If any of
the sentinel animals test positive on serologic evaluation, all other animals are killed and the process
starts again. The contingency measures applied in protection and surveillance zones are maintained
until the property has been determined to be free of disease [3, 4].
In 2005, Santa Catarina reported and investigated 83 notifications of reportable disease suspicions in
holdings with FMD-susceptible animals. The State investigated 30 notifications for vesicular
disease, 13 of which were due to trauma and 17 of which were due to diverse intoxications. In 2006,
Santa Catarina reported and investigated 201 notifications of reportable disease suspicions in
holdings with FMD-susceptible animals, 81 of which were investigated as vesicular disease
suspicions. These were all found to be unfounded, with 41 due to traumatic injuries and 40 due to
intoxication[4].
Santa Catarina did not report any suspected cases of CSF in 2005 and 2006; however three suspected
cases were reported in 2007. All of these were investigated and subsequently determined to be
negative for CSF [3].
Conclusions:
Brazil has effective disease control and response programs for FMD and other notifiable ruminant
and swine diseases. Santa Catarina has developed specific contingency plans for immediate action
in any emergency situation. The State handles animal health emergencies, establishes coordinating
committees and emergency animal health technical groups, defines strategies and plans of action,
and, when necessary, carries out the appropriate control measures within a timeframe compatible
with a state of emergency. Quarantine and movement restriction decisions are made by State
officials with input from Federal authorities. There are also systems for notification and training that
ensure emergency preparedness and response with a legal framework to authorize needed actions.
APHIS concludes CIDASC has the capabilities to respond rapidly and effectively to an animal
disease outbreak and limit the spread of the disease should an outbreak occur.
Release Assessment Conclusions
APHIS identified risk factors associated with importing FMD-susceptible species or their products to
the United States from Santa Catarina. APHIS discussed these risk factors in the context of the
potential for counterbalancing circumstances or applying appropriate risk mitigations to reduce the
risk of introducing and establishing FMD or other swine notifiable diseases under evaluation in the
United States. The risk mitigation procedures, which will be defined in the proposed rule, include
various forms of verification and inspection to which APHIS will propose that MAPA certify to
provide confidence that susceptible animals and their products meet acceptable export criteria.
