First PEDv Case in Over a Year Found in Manitoba


Update: Another case of PEDv was confirmed in Manitoba on June 2nd, just a week after finding the disease for the first time since January of 2015 in a sow barn in the province. The June 2nd case is a finisher barn in the southeast part of the province.

Manitoba’s chief veterinarian confirmed the province’s first positive porcine epidemic diarrhea virus (PEDv) sample since January of 2015 on Thursday.

The Manitoba Pork Council issued a notice on Friday saying the positive test results came from a batch-farrow sow barn. Producers within a five kilometre radius of the site have been alerted.

While hog farms across the U.S. and Eastern Canada have been devastated by the virus over the last few years, Manitoba hog farms have managed to stay mostly disease-free, despite trucks hauling between 65 and 70 thousand baby pigs south each week.

There have only been five on-farm cases of PEDv in Manitoba, with the most recent confirmation on January 21, 2015. As of November 27, 2015, all premises in the province that had previously tested positive were presumed negative according to protocol developed by the province’s chief veterinarian and swine veterinarians.

One of the tools for keeping the disease out, according to the industry, was a change in truck washing policy. Under an emergency order enacted in February 2014, the Canadian Food Inspection Agency allowed trucks to return to Canada without being washed at American facilities that are also visited by trucks known to be contaminated with PEDv. Trucks were sealed at the border and washed at certified wash facilities in Canada. However, the temporary order was not renewed and as of May 2, 2016, trucks must once again be washed in the U.S. before re-entering Canada.

“Working with the Canadian Pork Council and other provincial pork associations, Manitoba Pork will continue to press the federal government to amend the outdated regulation and allow transporters to wash at audited Canadian facilities, rather than in the U.S. where the disease is rampant,” said the council in the industry notice.

In light of the new PEDv case and the changes to truck washing policies, Manitoba Pork is recommending producers follow these measures:

  • Ensure that the trailers you allow on your farm have been thoroughly washed, disinfected and dried.
  • Exercise extreme vigilance with trailers coming back from assembly yards (known hotbeds for all swine diseases) and other major collection points.
  • Ensure that people coming onto your site follow strict biosecurity guidelines.
  • For trailers returning from the U.S., request that a second wash and a complete dry be done in Canada at a trusted facility.
  • All producers are encouraged to work with their veterinarian to review their biosecurity plans and ensure that their herds have the best practical protection from PEDv and other diseases.
