  • USDA Launches ‘Protect Our Pigs’ Campaign to Support the Pork Industry, Pig Owners, Veterinarians in the Fight Against African Swine Fever

    • Jun 15, 2022
    • USDA. Animal and Plant Health Inspection Service.

    • The United States Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) has announced new efforts to help prevent the introduction and spread of African swine fever in the U.S. Through an outreach and awareness campaign called “Protect Our Pigs,” APHIS will support commercial pork producers, veterinarians, and pig owners with information and resources to help safeguard America’s swine population and the pork industry.

      APHIS is deploying a variety of outreach efforts to support critical stakeholders. The new Protect Our Pigs website will house materials such as downloadable fact sheets and posters, instructional videos, shareable social media graphics, a new interactive biosecurity guide, and offer the latest disease updates. If African swine fever is detected in the U.S., APHIS will also be ready to respond immediately with actionable information and resources for pig owners and the public.

    • Feral swine can carry foreign animal diseases like African Swine Fever. While ASF has never been found in domestic or feral swine in the United States, there is no treatment or vaccine for it. That’s why surveillance is very important. Help protect U.S. pigs by immediately reporting sick or dead feral swine.

      WHAT TO DO: If you find a sick or dead feral swine with no obvious injury or cause of death, report it right away. Call the USDA-APHIS Wildlife Services program in your State at 1-866-4-USDA-WS. Don’t wait! Quick detection is essential to preventing the spread of ASF.

  • Protect Our Pigs: Fight African Swine Fever

    • USDA. Animal and Plant Health Inspection Service.

    • African swine fever is a deadly pig disease that spreads rapidly and affects domestic and wild swine. While not a threat to human health, the virus could devastate America’s swine, pork industry, and food supply. Whatever pigs mean to you—your livelihood or a pet—we’re all in it together. Protect our swine and keep the disease out of the United States.
