Porcine Epidemic Diarrhea Virus

PEDV, a coronavirus, has significantly impacted the US pork industry

Infected pigs will exhibit acute diarrhea within 12 to 36 hours of onset. PEDV has a nearly 100% death rate in pigs up to 17 days old; older swine will become extremely sick but will usually survive. PEDV is a production related virus and therefore affects producers of all sizes.

“What’s important to keep in mind is that PEDV is not a human health issue but rather a pig production disease, and we know that enhanced biosecurity measures are extremely important in containing the virus.” Dr. Paul Sundberg, National Pork Board vice president of science and technology

Key Points
If you suspect PEDV, contact your veterinarian immediately.

  • PEDV is spread by manure contamination on people, equipment, and vehicles.
  • Currently there is no vaccine. Prevention and supportive care are the only treatments available.
  • PEDV is not zoonotic and poses no risk to humans, other animals, or food safety.
  • Biosecurity is the best option recommendations should include:
    • Limiting traffic (people and equipment) onto the farm
    • Contamination between pens by thoroughly cleaning and disinfecting anything coming onto the farm
    • Isolating newly arriving animals and immediately separating sick animals
    • Wearing clean boots and coveralls, or using disposable boots and coveralls, using separate equipment, clothes, and supplies for sick animals

You and your vet are required to report the disease to the USDA. For the latest information visit www.Pork.org.
