Sign up for ASF and FAD preparation updates

African swine fever virus (ASF) is a serious, highly resistant, viral disease. Since August 2018, ASF has been rapidly spreading throughout China and Asia. U.S. swine industry organizations are working continuously on prevention and response to help keep ASF out of U.S. pig farms. ASF cannot be transmitted to humans, so it is not a public health or food safety concern. However, it can spread rapidly in pig populations by direct or indirect contact, and there is currently no vaccine or treatment. That’s why it is essential for the U.S. swine industry to be well informed and well prepared should an ASF outbreak ever reach the United States.

Foreign Animal Disease Preparation Guide

Check out our FAD Preparation Guide here. We've put together a compilation of information, steps to take on your farm, and resources to help you get started in preparing and protecting your farm from FADs. Learn what might happen if an FAD is diagnosed in the U.S., how you can prepare with tracability, disease monitoring, biosecurity, and contingency planning, and find a collection of helpful resources related to African Swine Fever and FADs.

Where is ASF?

Eleven countries in Asia have now confirmed outbreaks of ASF. Most recently in Indonesia.

    Feed ingredient biosecurity

    • Dr. Scott Dee - Transboundary Feed Transmission (32:20)
      Dr. Dee from Pipestone Area Research presents his research on the role of feed ingredients in the potential transmission of transboundary diseases. He describes the potential for feed ingredients imported into the U.S to harbor foreign pathogens, and the role of some feed mitigation strategies. From the 2018 ISU James D. McKean Swine Disease Conference. Read the full published article here.
