Sign up for ASF and FAD preparation updates

map of ASF in ChinaAfrican swine fever virus (ASF) is a serious, highly resistant, viral disease. Since August 2018, ASF has been rapidly spreading throughout China. 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. IPIC is offering workshops and assistance with foreign animal disease (FAD) preparation and Secure Pork Supply planning for your operation. Sign up for updates to hear about workshop dates and more.

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.
  • Dr. Cassandra Jones - Feed Mill Biosecurity (30:45)
    Dr. Jones from Kansas State University presents the latest findings related to feed mill biosecurity. Dr. Jones shares results on how long PEDV can be maintained within a feed mill, pathogen surveillance in feed mills, and feed mitigation strategies for both foreign and domestic pathogens. From the 2018 ISU James D. McKean Swine Disease Conference.
