A University of Minnesota study shows water-based cleaning and disinfection of swine transport trailers is the most effective approach to reduce the risk of PED.The University of Minnesota, with funding provided through the Swine Health Information Center Wean-to-Harvest Biosecurity Research Program, in partnership with the Foundation for Food and Agriculture Research and Pork Checkoff, has completed a study which evaluated cleaning protocols to mitigate the spread of porcine epidemic diarrhea.
SHIC Executive Director Dr. Megan Niederwerder explains researchers used a model to simulate the environment between a loadout and a contaminated trailer and compared an untreated positive control, an untreated negative control and three cleaning strategies, a dry scrape and bake followed by heat treatment, a volume hose flush out followed by disinfectant and a power wash followed by disinfectant.
Clip-Dr. Megan Niederwerder-University of Minnesota:
They were able to confirm that the simulated foot traffic between a trailer and a loadout area did indeed contaminate on farm, or their simulation of on farm from the PEDv infected feces. The positive control has PEDv contamination in the on-farm location.What they were also able to determine is that there were two cleaning strategies that really worked well to effectively reduce the level of contamination on farm as well as inactivate the virus.
