Swine Health Alert
Porcine Epidemic Diarrhea Virus Confirmed in Maryland
Swine Producers Alerted to Take Precautions
(Nov. 8, 2013)
– The Maryland Department of Agriculture (MDA) has confirmed a case of Porcine
Epidemic Diarrhea (PED) in southern Maryland and is alerting swine producers across the state to take proper precautions to protect their herds.
PED was first diagnosed in Great Britain in 1971, and Europe has had periodic outbreaks ever since, but the disease was not confirmed in the United State until this past May. It was confirmed in Maryland yesterday.
Primary clinical signs of the disease are: severe diarrhea in pigs of all ages, vomiting and high morbidity and mortality. It is generally spread among pigs and by infected feces transported into pig areas by trucks, boots, clothing, and the like. Once infected, the incubation period is very short (12-24 hours) and the virus is shed for 7-10 days. Producers who raise swine are encouraged to follow strict biosecurity methods and undertake disinfection procedures, which include the following:
•Limiting traffic (people and equipment) onto the farm,
•Thoroughly cleaning and disinfecting anything coming onto the farm,
•Enforcing downtime requirements and maintaining a log of visitors,
•Taking care when disposing of dead stock particularly if using a communal disposal method,
•Isolating newly arriving animals and continuing vet to vet discussions about animal health at the herd of origin, and
•Showering into the facility where practical and changing into clean boots and coveralls (veterinarians should also be careful not to track the virus between herds on their person, equipment or vehicles).
Producers who suspect their pigs are sick should contact their veterinarian immediately.
PED is NOT a “reportable” disease, which are diseases of great public health concern that must be reported to MDA.
More information and fact sheets on PED are available from the American Association of Swine Veterinarians here:
