Yes, not only were these major chains using the slime, but 70 percent of all the burgers in the United States contain the ingredient, too.
Pink Slime is the name given to ammoniated boneless lean beef trimmings. It’s an inexpensive beef filler. However, Pink Slime is unfit for human consumption until it is gassed with ammonia. McDonald’s and the other big chains are discontinuing their use of the slime after celebrity chef Jamie Oliver launched a campaign of criticism about the ingredient. Oliver brought the truth of the slime to the public’s eyes during his ABC television show Jamie Oliver’s Food Revolution. Oliver explained how the filler is cheaply sold as dog food, but after the ammonia gassing, it can be served to humans. One of the biggest frustrations about the slime is that it is widely used in school lunches.
