The virus 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. However, laboratory testing is the only way to diagnose PEDV.
The virus poses no food-safety risk. But federal and state animal health officials, in addition to the American Association of Swine Veterinarians and veterinarians at the National Pork Board, are actively monitoring the disease.
A notice on the National Pork Board web site stated that the virus is a production-related disease, not a trade-restricting disease as the virus is widespread in a number of European countries, Canada, China, Korea and Japan. In the US, PEDV has been found in a small number of herds.
