Porcine Epidemic Diarrhea

PEDv is a coronavirus that affects pigs only and is similar to Transmissible Gastroenteritis. It does not make people sick and it does not affect other species of livestock. PEDv does not affect pork safety and pork remains completely safe to eat.

The first detection of this disease in the U.S. occurred approximately one year ago, and since then it has impacted over 4,000 premises in 27 states. The most common sign of PEDv in swine is severe diarrhea, and mortality rates in pre-weaning piglets approach 100%. Older animals generally survive the infection but can shed the virus in their feces and through their respiratory tracts for an extended period.

The Agency of Agriculture encourages swine farmers to institute strict disease prevention measures to cut down risk of introducing the disease to their herd. Producers who see any signs of illness in their pigs should notify their herd veterinarian immediately to address the issue.Swine producers are encouraged to monitor for information coming from national industry groups such as the American Association of Swine Veterinarians (AASV) and the National Pork Board (NPB).
