What is Horse slaughter?

Horse slaughter is the practice of slaughtering horses to produce meat for consumption. Humans have long consumed horse meat; the oldest known cave art, the 30,000-year-old paintings in France's Chauvet Cave, depict horses with other wild animals hunted by humans. Equine domestication is believed to have begun to raise horses for human consumption. The practice has become controversial in some parts of the world due to several concerns: whether horses are managed humanely in industrial slaughter; whether horses not raised for consumption yield safe meat, and whether it is appropriate to consume what some view as a companion animal.
