Classical Swine Fever Surveillance

The Classical Swine Fever (CSF) Surveillance Program is designed to enhance surveillance for the rapid detection of CSF virus introduced into U.S. swine by testing targeted swine populations in high risk states. The program is implemented by APHIS in cooperation with the National Animal Health Laboratory Network (NAHLN). The swine populations targeted for surveillance include:

  • Swine highly suspicious for CSF
  • Sick pigs submitted to a veterinary diagnostic laboratory
  • Pigs condemned at slaughter by the Food Safety and Inspection Service (FSIS), and
  • Feral swine collected by Wildlife Services (WS)
