Claims that have circulated for years and resurfaced in 2026 say Oliver forced McDonaldโs to change its practices after he exposed โpink slime,โ beef trimmings treated with ammonium hydroxide, in hamburgers. He described in detail how workers make chicken nuggets. The posts encourage parents not to give this food to their children.
There is no record of Oliver suing McDonaldโs, according to several fact-checking groups and news archive searches. Oliverโs team has also confirmed he never took legal action against the company.
This story comes from a 2011 episode of Oliverโs TV show, โJamie Oliverโs Food Revolution,โ where he criticized the use of lean finely textured beef, also called โpink slime.โ Oliver demonstrated how the process works and said raw trimmings were โnot fit for human consumptionโ until they were treated with ammonium hydroxide to kill bacteria.
In early 2012, McDonaldโs said it had stopped using this product in its U.S. burgers in 2011, explaining that it wanted to match global sourcing standards. The company said the change was not because of any one event or campaign. McDonaldโs has repeatedly said its burger patties are made from 100% beef and contain no ammonia treatment. The U.S. Food and Drug Administration has long considered ammonium hydroxide โgenerally recognized as safeโ when used properly in food production. Many processed foods contain this additive.
Fact-checkers since at least 2018. News outlets would have widely reported a real lawsuit between Oliver and McDonaldโs, but no such coverage exists.
In 2012, a beef processor filed a defamation lawsuit against ABC News over its โpink slimeโ coverage, which included segments with Oliver. They settled that case privately several years later.
Oliverโs 2011 show drew attention to how meat is processed and sparked a public debate before McDonaldโs stopped using the ingredient. However, there is no evidence of a lawsuit or court decision stating that the food is toxic.
McDonaldโs and food safety regulators maintain that the products met standards at the time and that current offerings comply with U.S. requirements. Health experts generally advise limiting fast-food consumption for nutritional reasons unrelated to the debunked toxicity claims.
