Porcine Epidemic Diarrhea (PED)
What is USDA doing about PED?
USDA is working with veterinary diagnostic laboratories, veterinarians, swine producers, and State animal health officials and related swine industries to monitor this disease.
We are working to determine, to the extent possible, how long the virus has been here, the first location of the virus, and where the virus came from. Work is already underway in cooperation with States and industry, but it will take time to compile information, complete the analysis and determine final results.
What can I do about PED?
PED is similar to another, more familiar disease, transmissible gastroenteritis of swine (TGE). The only way to tell the two diseases apart is through laboratory testing. Owners should alert their veterinarian if pigs begin showing signs of this disease so that appropriate testing and diagnosis can occur.
To help prevent PED and other diseases, you should always follow good biosecurity practices.
Latest Information about PED
USDA's Animal and Plant Health Inspection Service (APHIS) is working closely with stakeholders to monitor the situation around porcine epidemic diarrhea (PED) in the United States. We received reports that animal feed may be a possible factor in transmitting this disease, so we partnered with the Food and Drug Administration (FDA) to investigate this possibility. At this time, here is what we know - we tested samples of feed and feed ingredients associated with one case of PED at the National Veterinary Services Laboratories (NVSL), with no positive results for PED antigen by polymerase chain reaction (PCR). However, our investigation with FDA is ongoing. We are also collaborating closely with American Association of Swine Veterinarians (AASV), National Pork Board (NPB) and the National Pork Producers Council (NPPC) on a broad epidemiological investigation to help identify any risk factors in the transmission of this disease.
