The role of harvest plant lairage and transportation in propagating the initial stages of an outbreak of Porcine Epidemic Diarrhea Virus in the United States in James F. Lowe, DVM, MS Diplomate ABVP (Food Animal) Lowe Consulting Ltd. Department of Veterinary Clinical Medicine, University of Illinois

What we learned 1.Trailers can become contaminated at packing plants but less than one clean trailer is contaminated for each contaminated trailer that arrives a the plant. 2.There is contact by EVERY driver with the plant lairage and that appears to be sufficient to allow for PEDV movement between trailers. 3.More contact between trailer and plant is associated with higher rates of PEDV spread

Air – low Spread by humans – moderate Vehicles or other equipment – moderate Pig movements – negligible Water – ‘not likely’ Feed pellets – moderate Bedding materials – low Illinois Rapid Response Team - Risks

Ohio Rapid Response Team - Risks Spread by workers – low Vehicles or other equipment – low AI or veterinary supplies – negligible Pig movements – low Feed ingredients / commercial meal mix – ‘not likely’ Feed pellets – high Water, air, shavings – negligible

Feed Risk – What Do We Know? PED is not a human health or food safety issue. The disease is impacting farms of a variety of sizes and production types and needs to be prevented through a variety of biosecurity procedures. PCR is an important tool to use in assessing contact with the virus There are multiple methods of PED transmission including environmental, transportation, feed systems and other vectors.

Feed Risk – What Do We Know? Within processing feed ingredients and feed processing there is a time x temperature that should be effective in inactivating the virus Post processing contamination can occur in different segments of the feed supply chain Pork industry stakeholders, veterinarians, producers, nutritionists and feed processors, agreed to a disciplined research approach to attack PED
