Classical Swine Fever

Classical swine fever (CSF), also known as hog cholera, is a highly contagious viral disease of swine. CSF was eradicated from the United States in 1978 after a 16-year effort by the industry and State and Federal governments. Today, only 16 other countries are free of CSF. While CSF does not cause foodborne illness in people, economic losses to pork producers would be severe if the disease were to become established again in this country.
