Pink slime

Meat by-product

Lean finely textured beef (LFTB)—also called finely textured beef, boneless lean beef trimmings (BLBT), and colloquially known as pink slime—is a meat by-product used as a food additive to ground beef and beef-based processed meats, as a filler, or to reduce the overall fat content of ground beef. As part of the production process, heat and centrifuges remove the fat from the meat in beef trimmings. The resulting paste, without the fat, is exposed to ammonia gas or citric acid to kill bacteria. In 2001, the United States Department of Agriculture (USDA) approved the product for limited human consumption. The product, when prepared using ammonia gas, is banned for human consumption in the European Union and Canada.
