First pink slime, now meat glue?

(WXYZ) - You’ve heard of pink slime, but there’s something else you may not know about that’s hiding in some of your favorite foods.

It’s called meat glue—and it’s a small scrap of meat, poultry and fish that’s used to bind larger pieces together. Its official name is transglutaminase.

The FDA says meat glue is safe, but that the potential danger comes from exposure the meat has had to bacteria.

Bacteria on the surface of food is usually killed off during the cooking process, but when exterior pieces are formed to make the center of a piece of meat, the cooking temperature may not get hot enough to kill any potential organisms before the meat is served.
