According to the U.S. Department of Agriculture, "pink slime" is being used for school lunch programs across the country.
The "pink slime" was pulled by some large restaurant chains such as McDonalds, Taco Bell and Burger King back in January.
Ammonium hydroxide is added to the "slime" which consists of beef by-products such as cow intestines that is more susceptible to E.coli and salmonella contamination.
Ammonia is not a health risk and is considered a processing agent so it is not required to be listed on any food label according to the FDA.
Heath officials say the by-products used in the food does not have the same nutritional value as pure ground beef does, but many parents say they would not want their children exposed to it for a long period of time.
