The first line of defense in protecting your herd from Porcine Epidemic Diarrhea Virus(PEDV) is a thorough biosecurity program. But over time even the best protocols can slip.

As you begin a new year and the industry faces this new virus, now is a good time to review and enhance the biosecurity measures that not only protect your herd, but ultimately help protect the U.S. hog population.

Whether its people, vehicles or pigs, it’s important to know the movements on and off your operation, and what exposure there may have been prior to coming to your site,says Bret Marsh, DVM, Indiana state veterinarian.

"Knowing the PEDV status of an area, herd or market lets you take precautions so you don’t bring the virus back home,"he adds.

Lisa Becton, DVM, Pork Checkoff’s director of swine health, suggests reviewing biosecurity protocols with your herd veterinarian and paying special attention to transport biosecurity efforts. You can find more suggestions here.
