An ABC News report in 2012 dubbed finely ground beef trimmings treated with ammonium hydroxide "pink slime". The chemical is sprayed on beef to kill bacteria like E. coli and salmonella. The FDA determined in 1974 that ammonium hydroxide was generally recognized as safe at a hazard level of 1, indicating little to no evidence of posing a hazard. Government reports and one author concluded the beef product known as "pink slime" or Lean Finely Textured Beef is safe to consume, though it raised public health concerns.
