Feed Additive to Mitigate the Risk of Virus-contaminated Feed

Publish Date: May 1, 2022

The introduction of Porcine Epidemic Diarrhea Virus (PEDV) in 2013 into the US swine industry pointed toward feed ingredients as the likely route of introduction. Subsequent research trials have documented viruses can survive in feed ingredients and complete feed for transoceanic shipping (30 and 37 days) and transcontinental shipping (23 days.) Authors of the transoceanic trial concluded: 1. Viruses can survive in feed, but survival is variable and depends on specific properties of each virus; 2. Certain feed ingredients or feed products present a better matrix for virus survival than others; and 3. Select ingredient matrices seemed to enhance the survival of multiple viruses. This fact sheet focuses on three research papers which evaluated compounds to mitigate virus-contaminated feed. The compounds are classified into two different groups. Foreign Animal Disease (FAD) viruses: African Swine Fever (ASF) and Foot and Mouth Disease (FMD); and Domestic viruses: Porcine Reproductive and Respiratory Syndrome virus (PRRSV), Senecavirus A (SVA), and Porcine Epidemic Diarrhea virus (PEDV) are discussed.

Volunteer Awareness: PEDV Biosecurity consideration for county fair swine weigh-in

Publish Date: January 20, 2016

Thank you for being a volunteer to work with our county fair swine weigh in. PEDV is a new disease that has raised the importance of biosecurity. This is important to our local pork producers and pork industry.  This is an educational opportunity for farm and non farm youth and adults. The principles are important for swine weigh-in but will continue to be important at fair time.
