>>35018089No, pink slime is just beef (or the chicken equivalent) put into a centrifuge to quickly separate the non-meat parts. The result is mushy meat that gets molded into patties and nuggets.
The controversy stems largely from being disinfected with trace amounts of ammonia, so the pink slime technically contains some. It was largely just the media trying to do a hit piece on McDonalds though, since ammonia is pretty harmless to humans unless you breath it in or decide to down an entire bottle.
