McDonald's announced that 'pink slime' or discarded beef cuts treated with ammonium hydroxide was no longer used in their burgers.
McDonald's previously used ammonium hydroxide to convert fatty beef offcuts into beef filler for burgers. Celebrity chef Jamie Oliver and others campaigned for fast-food chains to stop using the pink slime.
Todd Bacon, senior director of quality systems for McDonald's, said, "We made a decision to discontinue the use of ammonia-treated beef in our hamburgers. This product has been out of our supply chain since August of last year. This decision was a result of our efforts to align our global standards for how we source beef around the world."
