Manitoba’s first case of Porcine Epidemic Diarrhea Virus since last September was confirmed in a sow barn in the southeast part of the province, Manitoba’s Chief Veterinary Officer said in an update to the agency’s website.

It is the 11th provincial site found to test positive for PEDv since early 2014. As of May 2, 2017, nine of the 11 premises in Manitoba previously confirmed to have PED, are now determined to be PED Presumptive Negative. 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, the agency said.

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 May 2, 2017, 17,970 samples have been submitted for PED testing from 20 high-traffic sites.

Across Canada, in January 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 percent 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 2015, all Quebec premises positive for swine enteric coronaviruses (PED, Deltacoronavirus) are negative based on a negative status criteria similar to Manitoba's.
