That is disgusting
been seeing articles and some on TV about "pink slime" that is added to ground beef. We always buy chuck roasts and grind our own. 85%-15%. Save suet trim when we have too much on a chunk of meat so can always add if the meat is too lean.
The way they described "pink slime" was the trim and fat in small pieces that had been treated with an ammonia to kill the germs. Believe I'll continue to grind our own ground beef. Apparently it makes an exceedingly cheap filler in order to put on a few more pounds.
