Classical Swine Fever

Classical swine fever (CSF) is a highly contagious and economically significant viral disease of pigs. The severity of this disease varies with the strain of the virus, the age of the pig, and the immune status of the herd. Pigs infected with CSF virus may show clinical signs similar to many endemic diseases such as Salmonellosis, Porcine Reproductive and Respiratory Syndrome and Porcine Circovirus Associated Disease. Signs of illness can range from pigs huddling, skin discoloration, fever, and diarrhea. CSF is not a public health concern.

The United States eradicated the last case of CSF in August 1976; however, the disease is common in other parts of the world and therefore poses a risk to the U.S. If CSF is diagnosed in the U.S., the response would include controlled movement restrictions which will affect over-the-road transport of live animals and animal products.
