An industry-wide renewed focus on biosecurity is critical in controlling the spread and reinfection of Porcine Epidemic Diarrhea Virus (PEDV). It’s important to review biosecurity protocols with your herd veterinarian and enhance your farm’s biosecurity efforts, says Lisa Becton, DVM, director of swine health information and research for the Pork Checkoff.

Recommendations include:

  • Establish and visibly mark a “line of separation” that defines the areas to be used by off-farm workers and the areas to be used by farm or market personnel. There may be several such lines throughout a farm.
  • Talk to all service providers to ensure they understand the critical nature of PEDV and your new site-access restrictions. Don’t forget to include the farm’s non-production staff.
  • Completely clean, disinfect and dry trucks and trailers, inside and out, after every use. This starts by removing all bedding and debris, as well as using soap, detergent and disinfectant. Don’t forget to clean the cab. Several virucidal disinfectants can inactivate PEDV. Go to or for listings.
  • Wear coveralls and boots (both can be disposable) when going to a production site or packing plant. When leaving, remove protective clothing before entering the truck cab.
  • After transporting pigs, isolate and wash coveralls at a non-production site or throw disposables away off farm.
  • Restrict animal haulers’ access to the truck or trailer only. Load-out crews should not reenter buildings without washing, changing coveralls and boots first.
