Burgers are at the heart of the Golden Arches, and the fact is, McDonald’s USA serves 100% USDA-inspected beef- no preservatives, no fillers, no extenders- period.  

For a number of years prior to 2011, to assist with supply, McDonald’s USA used some lean beef trimmings treated with ammonia in our burgers.  We were among other food retailers who used this safe product.

At the beginning of last year, we made a decision to stop using this ingredient. It has been out of the McDonald’s USA supply chain since last August.  We wanted to be consistent with our global beef supply chain and we’re always evolving our practices.
