The Swine Health Information Center along with the National Pork Board, National Pork Producers Council, and American Association of Swine Veterinarians are sharing a recent United State Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) Veterinary Services (VS) literature review. The project looked at scientific evidence regarding whether non-animal origin ingredients of commercial swine feed could introduce or transmit viral pathogens of swine into or within the US. In the review, USDA experts identify, evaluate, and summarize current scientific knowledge published through March 2018. They also identify information gaps affecting decision makers, other stakeholders, and the scientific community. Support for future scientific research and/or risk quantifying models to evaluate the risk of entry of viral pathogens via specific feed ingredients from source countries and subsequent exposure to US swine populations are expected outcomes of this effort.
