Porcine Epidemic Diarrhea (PED) Virus

Last update: September 22, 2016
 
PED is a virus that causes severe dehydration and diarrhea in pigs. The virus is generally fatal in very young animals, however older animals can recover.
 
PED is not transmitted to humans or other animals. It is also not a food safety risk.
 
Strict biosecurity practices help limit the spread of the virus. All pork producers must maintain strict on-farm biosecurity procedures to keep PED out of the barn. It is critical that the entire industry, including producers, transporters and suppliers work together to reduce transmission through good biosecurity practices.
 
Symptoms may include:
  • Sows: loose feces, off feed
  • Piglets: watery diarrhea, dehydration, death
  • Weanlings/Feeders: watery diarrhea, almost all animals are sick, vomiting

PED is a reportable disease in Manitoba, so producers should contact their veterinarian immediately if animals show any signs of illness.

As of September 22, 2016, six of the ten premises in Manitoba previously confirmed to have PED, are now determined to be PED Presumptive Negative following a negative status protocol developed by the Chief Veterinary Office (CVO) and Manitoba's swine veterinarians.

A PED Presumptive Negative premises is a premises where the affected producer has implemented strict measures to eliminate PED from all pigs and pig contact areas and have confirmed the virus has been eliminated through repeated animal and environmental testing. However, a potential PED risk still remains within the manure storage system.


Environmental Testing
 
A voluntary PED testing program is ongoing at high-traffic sites that move or handle large numbers of pigs, including livestock assembly yards, federal and provincial abattoirs, truck-wash stations and livestock trailers. As of September 22, 2016, 14,494 samples have been submitted for PED testing from 20 high-traffic sites. Nine sites have tested positive for PED.

Follow-Up

When positive samples are confirmed either on-farm or at a high-traffic site, biosecurity measures are heightened. All parts of the supply chain are notified and encouraged to maintain strict biosecurity to reduce the spread of the virus. To confirm that PED has not spread within the province, follow-up has occurred with 220 Manitoba premises.

Support for Biosecurity Procedures

Under Growing Forward 2, the federal and provincial governments have developed Growing Assurance - Food Safety On-Farm to address challenges related to on-farm biosecurity. Although not specific to PED, producers, truckers, abattoirs and assembly facilities can access funds under the program to adopt systems and best management practices related to animal health and farm biosecurity.  
 
Manitoba’s CVO will continue to work with the pork industry to help affected producers eliminate the disease from their herds and prevent it from spreading.  Producers who have questions about PED, biosecurity and related issues are encouraged to contact the Manitoba Pork Council for their resources and expertise.
  
PED Across Canada

On January 22, 2014, the first Canadian case of PED virus was confirmed on an Ontario farm. A large scale PED outbreak occurred in the Ontario swine sector and a provincial response was initiated. Currently 80% of the PED positive herds enrolled in Ontario Swine Health Advisory Boards' control and elimination program are presumed negative. An elimination strategy was successfully implemented on the single Prince Edward Island farm in 2014. As of November 20, 2015, all Quebec premises positive for swine enteric coronaviruses (PED, Deltacoronavirus) are negative based on a negative status criteria similar to Manitoba's.
