PED Virus Found in Another High-traffic Pig Area in Manitoba

07 April 2014

CANADA - The Office of the Chief Veterinary Officer (CVO) has reported a second set of environmental samples, collected from a high-traffic pig site in Manitoba, have tested positive for Porcine Epidemic Diarrhea (PED) virus.

The samples were taken as part of an ongoing rapid-detection monitoring program for facilities that move or handle large numbers of pigs. Since it began in February, over 600 environmental samples have been submitted for testing. The first environmental positive result was reported on 14 March.

The investigation into how the PED virus arrived on Manitoba's single infected farm is complete. While the source could not be determined, infected feed and the movement of an infected pig onto the farm were ruled out. To contain the virus on the premises, all animal movement on and off the affected farm continues to be restricted. Animals on the farm are no longer showing symptoms and mortalities are within the normal range for this type of operation. Samples from 60 premises that had contact with the infected farm have been tested and all were confirmed negative for PED.

PED is a reportable disease in Manitoba. Producers are encouraged to remain vigilant with the necessary biosecurity protocols that prevent the spread of PED and are reminded they must report all suspected cases to their veterinarian. The CVO will continue to work with the pork industry to help any affected producers eliminate the disease from their herds and prevent it from spreading.

Producers who have questions about PED, biosecurity and related issues should contact the Manitoba Pork Council at 1-888-893-7447 (toll-free) or online at to access its resources and expertise.

There are now 46 farm premises that have tested positive for PED across Canada including one in Manitoba, one in Prince Edward Island, one in Quebec and 43 in Ontario. Manitoba remains in regular contact with chief veterinary officers and industry stakeholders across the country on this issue.

While many facilities have implemented significant biosecurity steps to limit the spread of PED, the risk is still present and producers who deliver pigs to these facilities must take extra steps to ensure they don’t bring the virus back to their farms. We continue to encourage all transporters to properly wash and disinfect their trailers after returning from the US or from premises that frequently ship to the US.
