Canada EHV-1 Restrictions Partially Lifted

According to a May 30 notice to the industry, the Ontario Racing Comission (ORC) has lifted the restrictions placed on one barn at the Campbellville Training Centre, a harness racing training facility located in Campbellville, Ontario, Canada. The ORC placed restrictions on the facility after horses previously stabled there tested positive for equine herpesvirus-1 (EHV-1).

On May 21, Adam Chambers, BVMS, the ORC's manager of veterinary services, told that two Standardbred racehorses tested positive for the virus, one of which was euthanized. The euthanized horse was previously stabled at the Campbellville Training Centre, but had recently left the facility.

On May 17, the ORC issued a notice to the industry stating that "horses stabled at the Campbellville Training Centre from April 29, 2013, are ineligible to race in Ontario until further notice."

On May 20, the commission issued another industry notice extending the EHV-1 restrictions: "This order has now been extended to include horses stabled or were stabled from April 29, 2013, at a private stable known as 'Les Cedres.' The stable is located near the town of Les Cedres, Québec, which is approximately 25 kilometers (about 15.5 miles) from the Ontario-Québec border, off the Autoroute 20."

The May 30 notice stated, "As of May 28, there have been no further confirmed cases of EHV-1 in Ontario since the restrictions on racing were imposed.

"At the request of the ORC, Dr. Scott Weese (DVM, DVSc, Dipl. ACVIM), an expert in infectious disease control at the Ontario Veterinary College, conducted an examination of the conditions at the Campbellville Training Centre. With his recommendation and expert opinion, the restrictions on horses that reside or resided in the upper barn of the Campbellville Training Centre are lifted effective immediately. This barn has had no affected horses in the recent EHV-1 outbreak.

"Barring any further clinical cases, the horses housed in the lower barn which housed the affected horses will be allowed to enter into races (make entries) and physically attend Ontario racetracks, on June 4, 2013. Trainers of these horses must continue to monitor and record temperatures twice daily and report any fevers to their licensed ORC vet." will continue to provide updates as more information becomes available.
