Last week, The Daily broke the news that the USDA planned to buy 7 million pounds of Boneless Lean Beef Trimmings (BLBT) – otherwise known as “pink slime” – for school lunches. Some reports state that 70% of prepackaged grind on retailers' shelves contain it. The resulting backlash has had more effect than anyone expected. Following a public outcry and hundreds of thousands of signatories to petitions to try to get the product out of schools, Beef Products, Inc. (BPI), the world’s leading producer of BLBT, has launched a new counteroffensive website “pink slime is a myth.” So where does the truth lie? Obviously, Boneless Lean Meat Trimmings sounds a lot more appetizing than “pink slime.” But whatever you call it, what is it? And how is it produced? The “pink slime is a myth” website says that BLBT is the meat and fat that is trimmed away when beef is cut. This is true as far as it goes. But BLBT isn’t quite the same as the bits of meat that you or your butcher might cut off the edge of a steak or other piece of meat. BLBT is the fatty trimmings that even BPI agrees couldn’t be separated with the knife. In the past, these trimmings were used for pet food or converted into oil rather than being served as hamburgers to people.
