Does McDonald's use 'pink slime' in burgers or beef treated with ammonia?

Nope. Our beef patties are made from 100% pure beef. We season with just a punch of salt and pepper, otherwise nothing else is added. No fillers, no additives and no preservatives.

Some consumers may be familiar with the practice of using lean, finely textured beef sometimes treated with ammonia, which is referred to by some as “pink slime.” We do not use this. Still curious about what's in our burgers.
