Porcine Epidemic Diarrhea Virus Detected in U.S.
Information provided by the American Association of Swine Veterinarians (AASV)

On Thursday May 16, 2013, National Veterinary Services Laboratories (NVSL), in close collaboration with Iowa State University Veterinary Diagnostic Laboratory (ISU-VDL), reported that Porcine Epidemic Diarrhea Virus (PEDV) has been detected in the United States. PEDV causes outbreaks of diarrhea and vomiting in swine. It is not a zoonotic disease, does not affect people, and is not a food safety concern.

Although this is the first known detection in the United States, PED exists in many parts of the world and is not considered a foreign animal disease in the US, but rather a transboundary disease.

The AASV is in contact with the USDA, state animal health officials, National Pork Board and National Pork Producers Council. Federal and state animal health officials are monitoring the situation. Development of an epidemiological survey instrument has begun. It is expected that herd veterinarians will be actively involved in the information gathering.

Veterinarians should contact the VDL to determine what samples are preferred.
