I don't recall where I read this, but (probably hundreds of years ago) some explorer in Africa was on a boat with some hunter-gatherers. A bloated, rotting dead rat floated by, they picked it up, said "yum" and dug in. They didn't get sick. I've also read some speculation that (initially) fire wasn't needed so much for cooking meat, because hunter-gatherers can (and did) accomplish the same effect by letting meat rot a little. Fire was more useful for vegetables.

So actual hunter gatherers probably had less need for antibiotics than a modern person thrust into a similar situation.
