Porcine Epidemic Diarrhea Virus (PEDV)
The USDA has confirmed that porcine epidemic diarrhea virus (PEDV) has been identified in the United States for the first time through testing at the National Veterinary Services Laboratory. This is not a new virus, nor is it a regulatory/reportable disease. Since PEDV is widespread in many countries, it is not a trade-restricting disease, but rather a production-related disease. PEDV may appear clinically to be the same as transmissible gastroenteritis (TGE) virus with acute diarrhea. Producers will need to work with their herd veterinarian with if any TGE-like symptoms appear and as always, maintain strict biosecurity protocols.
- Porcine epidemic diarrhea virus (PEDV) is a virus similar to transmissible gastroenteritis (TGE), another disease only affecting pigs. It is not zoonotic, so therefore it poses no risk to other animals or humans. Also, it poses no risk to food safety.
- PEDV has been identified in the United States in a small number of herds. The virus is not a new virus as it was first recognized in England in 1971. Since then, the disease has been identified in a number of European countries, and more recently in China, Korea and Japan.
- USDA, State Animal Health Officials, the American Association of Swine Veterinarians and veterinarians at the National Pork Board are actively monitoring this disease and will make recommendations to producers as necessary.
- PEDV is transmitted via the fecal-oral route and may appear to be the same as transmissible gastroenteritis (TGE) virus with acute diarrhea within 12 to 36 hours of onset. Herd veterinarians remain well versed in managing TGE-like diseases.
- The virus is a member of the Corona family and causes clinical signs very similar to TGE (Transmissible Gastroenteritis) including:
- acute outbreaks of severe diarrhea and vomiting
- significant mortality (50 - 60%) in piglets 7 days of age and younger
- incubation in 1 - 4 days
- Laboratory testing is the only way to diagnose PEDV.
- As always, producers who see any signs of illness in their pigs should notify their herd veterinarian immediately to address the issue.
- PEDV does not affect pork safety. Pork remains completely safe to eat.
