Rio de Janeiro, Brazil, now classical swine fever-free


The Brazilian state of Rio de Janeiro has been recognised as a classical swine fever-free zone by the World Organization for Animal Health (OIE).


Following the active surveillance activities in CSF-free zones, recommended by Brazil’s Ministry of Agriculture, Fisheries and Food Supply, the Agricultural Defense technicians of the State Secretariat of Agriculture are conducting clinical and serological surveillance in both technical and non-technical swine farms. This involves taking blood samples from a percentage of animals over eight months of age to evaluate the possibility of CSF virus circulation. The samples are sent to laboratories accredited by the Ministry of Agriculture.


An estimated 50 farms in Rio de Janeiro will participate in the survey, sampling more than 400 pigs. In addition to the farms where samples will be collected, another 10 farms will undergo clinical inspection of the animals.
