New research performed at Kansas State University (KSU) suggests that a commercial formaldehyde and organic acid blend product may offer the most effective means of controlling porcine epidemic diarrhea (PED) virus in swine feed.

Dr. Kurt Richardson, Anitox pathogen specialist and chief scientific officer, explained: “This research builds on earlier data published by Pipestone Veterinary Clinic and South Dakota State University, which identified PEDv-contaminated complete feed as a vehicle for infection of juvenile swine. 

“The latest work compared four chemical treatment options: Termin-8, sodium bisulfate, sodium chlorate and organic acids. Feed was treated with the various products individually and then contaminated with PEDv. Kansas State also evaluated the effect of these products in ingredients such as meat and bone meal, blood meal and spray dried animal plasma. Termin-8 offered the highest level of control in the complete ration and in all three feed ingredients throughout the 42 day period of the trial.”

Richardson explained that this work is important as it offers producers a critical control point in the battle against PED virus.

“By selecting feed treated with a high-performance formaldehyde pathogen control solution such as Termin-8, producers can be confident they’re not introducing PEDv to their animals through rations,” he said.
