INDEPENDENCE, Iowa — While there is much research underway on Porcine Epidemic Diarrhea Virus, there is a still a lot that is unknown, said Dr. Rodney \"Butch\" Baker, director of the Iowa Pork Industry Center at Iowa State University. Baker provided on update on the disease which has killed more than 5 million baby pigs in the nation\'s major swine producing states since it was first detected a year ago. He spoke at an informational meeting last week organized by Buchanan County ISU Extension and Outreach at Heartland Acres Agribition Center in Independence.
INDEPENDENCE, Iowa — Controlling Porcine Epidemic Diarrhea Virus requires diligent attention to biosecurity, said Mark Storlie, Iowa State University Extension swine field specialist. PEDV transfers via feces and survives in manure for extended periods of time, Storlie said during an informational meeting in Independence. During an outbreak of PEDV, affected animals shed a large amount of the virus into the environment. Contamination of trucks, equipment, clothing and footwear with feces can spread the virus. In June 2013 ISU researchers swabbed 670 hog trucks at seven packing plants before and after they unloaded pigs, Storlie said. The study found that 17 percent of trailers were contaminated with PEDV before unloading the pigs. Another 11 percent of trailers that were not contaminated with PEDV on arrival were subsequently contaminated during unloading so that 28 percent of trailers tested positive when leaving the plant.
