Dr. Chad Paulk, Kansas State University, led a project to understand the best flushing, thermal processing, and decontamination techniques for a feed mill after exposure to PEDV, PRRSV, and SVA. In addition to PCR testing for viral RNA, infectivity of feed and environmental samples collected after utilizing the decontamination techniques were evaluated using swine bioassays. Overall, data showed that chemical flushing, thermal processing, and facility decontamination reduce the quantity of viral RNA, but more research is needed to understand how these techniques affect virus infectivity.
