Want to take a second look at that burger you’re about to bite into? The “pink slime” that was made famous by the food movie Food Inc. has reportedly made its way into the majority of America’s meat. A recent estimation says that up to 70 percent of ground beef at grocery stores contain the slime, and up to 25 percent of all hamburger patties. The slime is made up of low-grade trimmings that come from the most contaminated parts of cows and was once only used in dog foods and cooking oil. But a new treatment has made the slime safe to eat, according to the USDA. The gelatinlike substance is made up mostly of connective tissue and therefore has no nutritional value. USDA organic meat is said to contain no slime, but there have been no measures put in place to force meatpackers to reveal how much slime their beef contains.
