African swine fever (ASF) is a contagious and deadly virus that’s infecting pigs in many countries. It’s harmless to humans, but it can be present in foods made from pork. People can spread the disease by bringing pork or pork products with them when they travel from a country where ASF exists.
ASF hasn’t reached the United States yet—and we want to keep it that way.
You could carry ASF into the United States without knowing. Take these steps to stop the spread:
- Don’t bring foods containing pork with you when you travel.
- When you enter the United States, declare all meats, animals, and animal products to U.S. Customs and Border Protection (CBP).
- Tell CBP if you have been on a farm, near livestock, or near wild pigs.
- After you return, wait at least 5 days before you visit any animal facility with pigs. This includes farms, livestock markets, zoos, circuses, and pet stores with pot-bellied pigs.
- At the airport, CBP agents may dispose of food containing pork or any meat that looks like pork before you enter the U.S. Mainland or a U.S. Territory.
- This includes homemade dishes, whether they are cooked or frozen.
- These rules apply to items in both your carry-on and checked baggage.
Travelers From Puerto Rico and the U.S. Virgin Islands
ASF was recently detected in the Caribbean. For this reason, certain pork products are prohibited from transiting between the U.S. Mainland, Puerto Rico, and the U.S. Virgin Islands. All prohibited products will be confiscated.
USDA prohibits or restricts the entry of many other agricultural products from Puerto Rico and the U.S. Virgin Islands into the U.S. Mainland, including most fresh fruits and vegetables.

Many Americans travel to the Caribbean each year, and cruise activity in the region continues to grow. Expanding cruise routes, larger fleets and improved port infrastructure have made island-hopping or traveling from one island to another, increasingly accessible giving travelers more opportunities to visit multiple destinations by boat or ferry.
