Kansas State University Conducts Research on Persistence of Swine Viruses in Feed Ingredients

02/07/2020

Scientists at the College of Veterinary Medicine, Kansas State University have completed a study on the stability and infectivity of classical swine-fever and pseudorabies viruses on imported ingredients.  The study simulated a 37-day trans-Pacific shipment on twelve ingredients including conventional and organic soybean meal, pork-sausage casings, dry dog food, and additives including lysine, choline and a vitamin feed additives.

 

The study demonstrates the potential danger of introducing porcine epidemic diarrhea (PED) virus and other infections in imported ingredients from Asia. It is general accepted that the 2013 outbreak of PED was introduced on either feed bags or ingredients imported from China where infection is endemic.

 

The study is also determined that pseudorabies virus has increased stability, evidenced by the presence of viable virus in nine of twelve tested ingredients at the conclusion of the study period.
