Pink slime, amonia-treated meat that was rejected by fast food outlets like McDonald'sl and Burger King is reportedly being brought in by the tons for the nation's school lunch program.

The U.S. Department of Agriculture is purchasing 7 million pounds of the " pink slime" for school lunches, according to The Daily.

"Lean Beef Trimmings," the official term is a ground-up combination of beef scraps, cow connective tissues and other beef trimmings that are treated with ammonium hydroxide to kill pathogens like salmonella and E. coli. It's then blended into products like ground beef and hamburger patties.

"We originally called it soylent pink," microbiologist Carl Custer, who worked at the Food Safety Inspection Service for 35 years, told The Daily. "We looked at the product and we objected to it because it used connective tissues instead of muscle. It was simply not nutritionally equivalent [to ground beef]. My main objection was that it was not meat."

A study concluded that the trimmings are a "high risk product," but "scientists in D.C. were pressured to approve this stuff with minimal safety approval" under President George H.W. Bush's administration. The USDA asserts that its ground beef purchases "meet the highest standard for food safety."

A public outcry against the "slime" is led perhaps most prominently by celebrity chef Jamie Oliver.
