PEDv found in hogs on second SE Manitoba farm

A finisher operation in Manitoba’s livestock-intensive southeast has been confirmed as the second farm in the province to host hogs with porcine epidemic diarrhea (PED).

According to the office of Manitoba’s provincial chief veterinary officer (CVO), the new case was identified while the CVO was investigating a PED-positive sample from an unnamed “high-traffic site.”

The CVO’s office noted it’s “been advised the animals on this farm have shown no symptoms of PED.”

The office will now identify other premises that have been in contact with this farm, and investigate how the virus arrived at the premises, the CVO said in a release Friday.

Karl Kynoch, the chairman of Manitoba Pork, said in a separate statement that the producer in this case is “working closely with their veterinarian and the CVO to contain the virus on the farm and take the necessary steps to clean up the site.”

Manitoba’s first on-farm case of PED was confirmed in February at a wean-to-finish operation, also in the southeast — a region considered the province’s “hog alley.” [Related story]

Since then, the virus has also been confirmed in hogs at two unnamed “high-traffic” off-farm sites, one in the southeast and one in western Manitoba. In both cases the hogs are believed to have picked up the virus at the sites, not on their farms of origin. [Related]

In all, eight such off-farm sites — which, for example, could include hog assembly yards, abattoirs, truck-wash stations and/or livestock trailers — have turned up positive hog or “environmental” samples.

As of Friday, the province said, a total of 1,187 samples have been submitted for PED testing from 18 such high-traffic sites.

PED’s symptoms include diarrhea, vomiting and dehydration and can be severe and often fatal in newborn and nursing piglets, though older hogs often show less serious symptoms and generally recover.

The PED virus (PEDv) is not a food safety issue, nor does the virus affect humans, the province noted in a release.

“Your responsibility”

PED, which until last year had been seen only in parts of Asia and Europe, arrived in the U.S. early last year and has since been confirmed in hogs on over 6,400 farms across 30 states.

In Canada, the virus was first confirmed in January on properties in southwestern Ontario, where most of that province’s 58 on-farm cases to date have been detected. The second Manitoba case, and previous on-farm cases in Quebec and Prince Edward Island, bring Canada’s total on-farm cases of PED in hogs to 62.

Manitoba Pork again emphasized Friday it’s “crucial” for producers to maintain biosecurity protocols and contact a veterinarian immediately if animals show signs of illness.

Strict biosecurity practices, such as the proper washing and disinfection of all trucks and trailers coming onto a farm site, can reduce the potential for outbreaks, the organization said.

“It is your responsibility to make sure that all trailers are clean before they back up to your barn.” — Network
