follow on notification of vesicular disease suspicions, including the appropriate information flow
and the technical procedures to be followed. All official veterinarians are trained in carrying out this
initial response [4].
After completing the initial records and before leaving the field, the official service veterinarian on
site will inform his or her work team, immediate superior, and the regional representative of the
emergency diseases group about the suspicion. Until the investigation has been completed, animals
cannot be moved from the holding, from any adjacent holdings, or other holdings that have traded
animals, products, or equipment with the affected holding [4].
Once the disease suspicion has been ruled out, the official services veterinarian records the final
diagnosis, lifts the animal movement restrictions on the affected and related holdings, and
communicates the results to his or her immediate superior, work team, and the regional
representative of the special group for emergency diseases. Most investigations concern false
reports, traumatic injuries, intoxication and malnutrition rather than actual OIE reportable disease
[4].
If the official veterinarian determines that a disease suspicion is valid and needs to collect specimens
for laboratory analysis, the involved holdings will remain under quarantine until testing is completed
and negative results returned. Positive results would extend the quarantine until disease control
measures are completed. The veterinarian immediately sends the laboratory materials, along with
the appropriate submission forms, to a MAPA laboratory. The official veterinary service sends
additional teams to provide extra surveillance around the primary holding and investigate the
movement of susceptible animals in and out of the affected holding within the 60 days prior to the
most probable first occurrence of the disease [4].
If the investigation confirms FMD, an animal sanitary emergency state is established during the
completion of the investigation and eradication efforts. If tests do not detect FMD, differential
diagnostic tests are carried out for vesicular stomatitis, bovine viral diarrhea, infectious bovine
rhinotracheitis, and bluetongue. Specific procedures exist for each of these diseases and would be
carried out if any of the diseases were detected [4].
Santa Catarina reported 83 notifications of reportable disease suspicions in holdings with FMDsusceptible
animals in 2005. These notifications were investigated. Thirty involved a report of
possible vesicular disease. Of the vesicular notifications, none were confirmed to be FMD. Instead,
13 were determined to involve trauma and 17 involved a variety of toxic plant exposures. In 2006
there were 201 notifications of suspicious reportable diseases in holdings containing FMDsusceptible
animals. Eighty-one of these were related to possible vesicular disease with 41
eventually determined to involve trauma and the remaining 40 to involve toxicosis [4].
Official veterinary services staff also conduct inspections during their regular duties. These duties
include control of animal movement at permanent inspection stations or by mobile inspection teams;
antemortem and postmortem activities at slaughterhouses; supervision of livestock congregations;
and direct inspection at rural holdings [4].
