You may have heard the stories about McDonald’s hamburgers not rotting, even after long periods of time – with the corresponding implication that they must be loaded with chemicals.
At the link above, there is a careful scientific examination. It’s fascinating to me to see this attention done. If it’s not fascinating to you here’s the final story:
1. True: they don’t mold.
2. But this is due to the fact that they dehydrate because the burgers are small. Basically, they turn into jerky. Jerky doesn’t need to have heavy preservatives (the native Americans didn’t have a large chemical industry). So, the fact that McDonald’s hamburgers don’t mold is no reason not to eat them.
