The Humane Society of the United States is backing proposed legislation in Congress to permanently ban horse slaughter in the United States. The two measures they’re supporting also calls for prohibiting the sale of horses to other countries for human consumption. HSUS Ag Director Joe Maxwell says horses aren’t built to be humanely slaughtered. Maxwell doesn’t believe slaughtering horses is the best means of dealing with overpopulation of the animals. He says there are other alternatives like putting the animals down or using proper breeding methods. Maxwell says euthanizing a horse doesn’t cost any more than paying a monthly boarding fee for the animal.
