In the winter of 2013-14, the U.S. pork industry was taken by storm when Porcine Epidemic Diarrhea virus (PEDv) ravaged herds across the country. The winter of 2014-15 was much less severe, but that doesn’t mean producers are out of the woods. Some researchers suggest producers will see a higher incidence of the virus this fall and next year, as new gilts that haven’t been exposed to the virus enter the herd.

Dr. Greg Cline, Technical Manager for Swine Enteric Vaccines at Boehringer Ingelheim Vetmedica, Inc., says there is now a website that serves as a clearinghouse on PEDv information for producers and veterinarians. Called the “SOURCE” for PED management (, it walks users through a holistic, or systematic, review of their risks.

“It gives suggestions of how you can mitigate that risk, and ultimately drive down to the creation of an individual herd plan,” says Dr. Cline.

It’s valuable for both producers and veterinarians, he explains. “The system review of the herd plan and of the risks associated with PEDv stand by themselves,” he says. “The process is beneficial to veterinarians as well as producers.

Unique On-Line Tool
The step-by-step process is a unique on-line tool that makes it easier for veterinarians to comply with USDA mandatory reporting requirements in terms of review and discussions, says Dr. Cline.  

The website also helps producers, along with their herd veterinarian, to determine whether you should eliminate, diminish or prevent the virus from entering your farm by first taking a systematic approach to PED control and management. The process involves focusing on six key areas, identified with the acronym S.O.U.R.C.E.:

“State” – State the desired goals you hope to achieve.
“Obtain” – Obtain your current herd health status.
“Understand” – Understand the risks you and your operation face when you’re up against PEDv.
“Reduce” – Reduce the risks of infecting or re-infecting your herd.
“Construct” – In conjunction with your veterinarian, construct solutions that include a variety of options.
“Execute” – Execute and monitor solutions that you and your veterinarian have identified for your operation.

Disease Management
Producers have a responsibility to do all they can to control disease through best management practices to protect their own herd as well as those in the surrounding area and beyond. The SOURCE website provides a step-by-step process for developing a plan that can be used for control on any disease, including PEDv.
