Quebec turns up second case of PEDv in hogs

Quebec has confirmed its second instance of porcine epidemic diarrhea (PED) in hogs, this time at a feeding operation in the Monteregie district.

Biosecurity measures have been ramped up “promptly” at the unnamed farm to avoid the spread of the PED virus (PEDv) to other hog operations, the provincial ag ministry said in a release Thursday.

The case marks the province’s only other confirmed on-farm instance of PED in hogs since Feb. 22, the ag ministry said.

The ministry reiterated the virus poses no threat to human health or to food safety. The virus causes diarrhea, vomiting and dehydration in affected hogs and is generally fatal in very young piglets, though older animals usually recover.

According to La Terre de chez nous, the news organ of Quebec’s Union des producteurs agricoles (UPA), the discovery at the farm in the province’s southwest followed confirmation of the virus at an assembly yard at Roxton Falls, about 65 km west of Sherbrooke.

Martin Pelletier, director of the province’s swine health team (EQSP), was quoted by La Terre’s Pierre-Yvon Begin as saying the feeder hogs at the affected farm haven’t really shown a higher-than-normal mortality rate.

The hogs at the Monteregie operation all came from Ontario, Pelletier told La Terre, also noting the affected farm is relatively isolated, with no other commercial-level hog operation within a 10-kilometre radius.

The latest finding brings Canada’s total of on-farm PEDv cases to 70, including 63 in southern Ontario, four in southwestern Manitoba, Quebec’s two cases and one in Prince Edward Island. Ontario, where Canada’s first PEDv case was detected early this year, hasn’t logged a new confirmed case since July.

An environmental swab test in the office of a hog assembly yard in Alberta turned up positive late last month for PEDv, marking the first detection of the virus in that province. [Related story]

In the U.S., where the virus made its first North American appearance early last year, PED has since been detected at over 8,800 hog operations across 32 states. — Network
