This is an excellent article, however, it should be noted that while there are no horse slaughter plants in the US, that country does export horses to be slaughtered in Mexico and Canada.
Trailer loads containing 28+ loose horses cross at one of 8 designated ports of entry to Canada where the trailers are sealed by the CFIA, then depending on the destination of the meat from the horses, the horses are either slaughtered within 4 days of arrival at the plant or held for six months as per the European Union regulations stating that a horse must reside in the country of slaughter for six months prior to slaughter.
Any horse presented for slaughter in Canada must be accompanied by an ‘Equine Information Document’, which is to include their medication history. However, those who fill out the easily “fudged” documents operate purely on an honor system.
