Results of Stalosan F Efficacy Testing Against PEDv

December 24, 2013 — 

The results of a National Pork Board funded study indicates that Stalosan F is not effective at inactivating PED virus in swine feces on metal surfaces. The study, conducted by Dr. Derald Holtkamp at Iowa State University, was designed to replicate what is found in livestock trailers after fecal and other organic matter has been removed by scraping and sweeping, but not washed. The hope was that the product might be efficacious at inactivating the virus in the presence of fecal material. These findings indicate that producers should not expect to kill the PED virus with the use of Stalosan F disinfectant powder in a hog trailer that has not been properly washed. Thorough washing, disinfecting, and drying of hog trailers between loads of pigs should be accomplished whenever possible. The effectiveness of Stalosan F disinfectant in trailers that have been properly washed is unknown. The entire study may be viewed on the NPB web site.
