PEDV continues to spread

PEDV continues to spread

27 states in the U.S. have confirmed PEDV cases while Japan suspect PEDV has entered its borders.

Arizona reported its first confirmed case of Porcine Epidemic Diarrhea virus (PEDV) this week, which now makes the virus present in 27 states.

For the week of March 2, the number of PEDV cases reported was 274.  This is down from February weekly total but the fifth highest since the disease was discovered.

Realizing, U.S. hog operations are not required to report PEDV cases. Therefore the weekly cases reported by the American Association of Swine Veterinarians (AASV) are based on testing by the National Animal Health Laboratory Network.

Each case tested could represent a single hog or an entire herd. The virus strives in cold temperatures the number of cases is likely to decline as the temperatures rise.

According to AASV, Idaho, Oklahoma, North Dakota and Texas are currently requiring statements regarding the PEDV status of the herd on Certificates of Veterinary Inspection.  

As result of PEDV losses threatening to constrain an already tight supply of hogs, the hog market prices has soared and setting records over last several weeks. Utlimately, the consumer will see higher prices for pork at the meat counter.

PEDV is only an animal health issue, not a food safety issue and people cannot get sick from eating pork.


A case of PEDV was suspected on farm in Japan. As a result, a conference was held to educate the country’s pork producers on preventative measures to protect the farms from introduction to the virus.  Authorities have also called for voluntary ban on the movement of hogs near the area.

Canada continues to report more PEDV cases since the first case of the virus was confirmed in the country in late January.

The Directorate General of Livestock, Ministry of Agriculture, recognized the existence of PEDV in the Dominican Republic.
