The not-rotting Big Mac story is just a fake, a bit of propaganda?
Seems that famous "non-rotting" MacDonald's hamburger isn't unique. Someone actually did the research and NO cooked hamburgers showed rotting after two weeks. I suspect it might have something to do the meat being cooked to destroy bacteria in it, and under controlled conditions flies and such aren't given access to the meat to lay eggs and cause rotting. Plus, I've seen the photo of the "non-rotting" Big Mac and noticed that all the uncooked "un-sterilized" (my choice of word, couldn't think of a better) ingredients, such a lettuce, which would quickly wilt and rot had been removed.
Seems like a propaganda set-up to me. LOL
