Interesting - I would think that cooking it in a four hundred degree F oven would take care of most possible food bacteria, even if left on the bathroom of the bus station for an hour (before cooking not after

).
What about salmonella, etc in foods...does cooking not kill all the bacteria and fungus, or is there still a risk? I can see a risk for under-cooked food but how about "over-cooked" food such as well done beef and chicken and stews that simmer for a few hours?
This is a serious question btw as I like poached eggs and sushi, which i know have to have care taken. But I hear there is bad beef etc from time to time in stores.
Are there some kind of poisons that bacteria and fungus produce in foods that still remain dangerous after thorough cooking?
