A slaughterhouse, also called an abattoir (French, ultimately from the verb abattre which means "to strike down"), is a facility where farm animals are killed and processed into meat products. The animals most commonly slaughtered for food are cattle (beef and veal), sheep (lamb and mutton), pigs (pork), poultry, and horses. (Most horse slaughter is done in Europe, but horse slaughter also takes place in the USA and Canada for meat export to Europe and Japan and for the pet food market at home in the U.S.).
