In meat its used to kill bacteria and antimicrobial to control pathogens.
This is not used when butchering beef such as beef cuts, but when processing beef sometimes. Typically when beef scraps and parts of the animal that would not be fit for human consumption are included as filler.
It's ammonium hydroxide - not naturally occurring ammonia. The only reason it's being used is to prevent things like trace amounts of fecal matter or other nasty parts of the cow that they use. They won't comment on it and I don't think they still do, but at one point cow bone was part of the filler used in the processed beef for McD's patties. A trusty bone grinder, eventually worked into a consistency of a fine powderlike existence. No label or notice issues as its technically 100% "beef".
