New Study Connects PEDv Virus And Contaminated Feed

New Study Connects PEDv Virus And Contaminated Feed

August 18, 2014 – Swine can contract the deadly PEDv virus by eating contaminated feed. That’s the finding of a first-of-a-kind study.

Dr. Scott Dee, director of research at Pipestone Veterinary Services in Pipestone, Minnesota, told DTN on Monday he is confident his research proved a definitive link between contaminated feed and the virus.

In the study, Dr. Dee and his team of researchers examined three farms in Iowa and Minnesota where PEDv was diagnosed in January 2014. All three sites emphasized strict biosecurity.
The study found a “….relationship between the delivery of at-risk feed and the onset of clinical signs [of the virus]………within two days post-delivery of at-risk feed.”

Researchers found that, at all three sites, the farms experienced “an unexpected feed outage which required an ‘emergency’ delivery.” Although nearly all of the feed had been consumed, researchers found the PEDv virus in feed samples from the sides of the bins. Then, in a controlled experiment, Dee and his researchers found swine that consumed the PEDv-laced feed contracted the virus.

Dee said the study is not meant to point fingers at any one segment of the swine industry. Instead, he says it should serve as a wake-up call for producers to create biosecurity standards for protecting animals from contaminated feed.
