African swine fever (ASF) is a virus that affects both domestic and wild pigs. It spreads very quickly and kills most pigs that get it. ASF has never been found in the United States. Humans cannot get ASF, but they can carry it on clothing, shoes, and equipment. An outbreak in the United States would have devastating economic effects on the swine industry.

Don’t bring it home

  • International traveler could carry this disease back without knowing it. Take these steps to help keep U.S. pigs safe:
  • Understand the risk
  • Take extra precautions
  • When visiting farms abroad declare items and farm visits
  • ASF can be carried on clothing, shoes, and hands.
  • It can also survive for months in pork products.
  • Bring back only safe food and souvenir items.
  • Check to know what items can enter the country.
  • Declare any overseas farm visits to U.S. Customs when re-entering the country.
  • If you visit any farm outside the United States, follow the farm’s biosecurity protocols during your visit.
  • Wear site-specific footwear and coveralls/clothing, and dispose of this protective gear before leaving the farm. If this gear isn’t offered, wash and disinfect or throw away your shoes and clothes before returning to the country.
  • When you return to the United States, don’t enter a farm or other location with pigs (including livestock markets, zoos, circuses, and pet stores with pot-bellied pigs) for at least 5 days.
