According to ABC News, three national supermarket operators have decided to stop buying ground beef that contains the filter which is described as pink slime. Federal regulations say that the filter known as “lean, finely textured beef,” meets the food safety standards. It can be unsafe and is an unappetizing example of industrialized food production. On Wednesday, Super Value customers mentioned that they are concerned and want it to stop carrying products containing the filter.

Also, the Food Lion chain that’s owned by the Belgian Delhaize Group mentioned also on Wednesday that it plans to stop carrying fresh ground beef with either of two similar filters. Both are made with beef trimmings left over from other cuts.

Christy Phillips-Brown is a spokeswoman. She emailed a statement saying “companies are working with suppliers to make the change. The company guarantees the 80% lean ground beef is already selling but doesn’t contain any filters.”

Safeway Inc., which operates Genuardi’s and Dominicks chains, as well as Safeway stores, said Wednesday also that it will stop selling fresh/frozen ground beef with the filter, a low-cost additive  which has been used for years. It’s made from fatty bits of leftover meat that are heated, spun to remove any fat, compressed in to blocks and exposed to ammonia to kill bacteria. Producers often mix the filter into fattier meat to produce an overall leaner product and reduce their costs.
