Thousands of American horses flow over the north and south borders of the US to be processed as meat. Canadians need to demand that this atrocity be stopped. It is a good thing that news outlets, such as Global News Canada, are bringing the Canadian horse slaughter issue to light. ~ HfH

Health Canada and the Canadian Food Inspection Agency have identified a long list of commonly used veterinary drugs that have been banned for use in food-producing animals. Global News takes a look at some of the most common banned drugs administered to horses:
Phenylbutazone or PBZ, nitrofurazone and clenbuterol
One of the most frequent treatments is phenylbutazone – or PBZ. It’s a painkiller and anti-inflammatory used so often that it’s been dubbed “horse aspirin.”
PBZ was first marketed as a treatment for arthritis and gout in the United States in 1952. But within three years, links to potentially fatal blood disorders were discovered. As a result, the U.S. Food and Drug Administration banned PBZ for use in food-producing animals. The FDA says there are no safe levels of PBZ for human consumption.
In an Irish Veterinary Journal article published in 2010, PBZ is called “the most potent and effective pain relieving agent available in equine medicine.” But the authors warn, “The difficulty with Phenylbutazone is that it, or its metabolite, can cause aplastic anaemia in children. If a child were to consume an animal-based product containing even the minutest amount of bute or its metabolite then the child may develop plastic anaemia,” the article warned.
And recent research indicates it’s unclear how long it takes PBZ to leave the equine’s body, if ever. “Traces of PBZ will remain as a contaminant of horse meat in previously treated horses for a very long and as yet undetermined period of time,” according to an article published in the scientific journal Food and Chemical Toxicology in 2010.
