Declaring Farm Visits in ASF Positive Countries to Customs

When returning to the United States after visiting a farm or being in contact with animals in a country (or countries) with African swine fever (ASF), or any other foreign animal disease, you should declare this information to US Customs and Border Patrol via written form, airport kiosk, or verbally. Then you should be diverted for an ag secondary screening by an ag specialist. The Swine Health Information Center (SHIC), National Pork Board, National Pork Producers Council, and American Association of Swine Veterinarians are asking you to report your experience if you are not diverted for secondary screening with return to the US following overseas travel.

If you are NOT diverted for secondary screening after declaring you have been on a farm or in contact with animals in an ASF or other foreign animal disease positive nation, please email the following to psundberg@swinehealth.org:

  • Your name (optional – please specify if you do NOT want your name shared)
  • Country (or countries) visited
  • Date and time of return
  • Airline and flight number
  • Arrival airport
  • Declaration method (written form, kiosk, or verbal)
  • Customs and Border Patrol employee name, if possible (displayed on right side of shirt)
  • Any other pertinent circumstances

Dr. Sundberg will be aggregating this information and the organizations will share with US Customs and Border Patrol to help identify any weaknesses in their protocol and systems.

ASF is endemic in Sardinia, most countries of subSaharan Africa, and some West African countries. Since August 2018, the spread of ASF through Russia, Belgium, the Caucasus, the Baltic states, Poland, and China has been monitored. At present, ASF has never been reported in the United States, Canada, Australia, or New Zealand.

Thank you for your help as we continue to implement steps designed to reduce the risk of ASF spreading to the US swine herd.

Funded by America’s pork producers to protect and enhance the health of the US swine herd, the Swine Health Information Center focuses its efforts on prevention, preparedness, and response.
