Re: “Canada’s horse slaughter industry needs to be regulated,” (The Hill Times, May 12, p. 10). We should not be misled into thinking that horsemeat is safe for human consumption. Each year, Canada kills tens of thousands of horses for meat, yet the vast majority of these horses are from the U.S. where horses are not raised for food and are routinely given drugs that are dangerous to humans. The regulatory system currently in place does not track the lifetime medical history of horses. Instead, the Canadian Food Inspection Agency relies on the Equine Identification Document, a voluntary declaration that has been repeatedly proven to be unreliable and open to fraud, which only requires to state “to the best of their knowledge” that their horse has not received banned drugs for the previous six months. However, there is a long list of drugs that are banned for life in animals raised for meat, including phenylbutazone (“horse aspirin”) and clenbuterol. There is no scientific evidence that phenylbutazone ever leaves the body and it has proved fatal to humans. Tracking the complete history of horses is an almost impossible task when many horses that end up at auctions and feedlots come from unknown origins. It is time to crack down on the horse slaughter industry. I urge Parliament to enact legislation, Bill C-571, to dramatically improve regulations. Laura Cull Kelowna, B.C.
