I know a man who swears by drinking a shot or two of vodka, or some swigs of everclear, shortly after consuming. He says it kills bacteria and minimizes his chances of getting the type of "food poisoning" that can happen.

I don't consume, so can't speak for his advice, except to say that some others have tried it and say that it's very helpful. I don't know how much is psychological or placebo effect.
