You can just sick from vegetables too. In fact, as much as I think I should eat more of them it's frustrating how I have to check for rot and other similar things far more often then I do with processed foods.

I know when I make something with fruit or vegetables I'll go through, rip off all the black or dark parts, throw out any rot. Often if I see rot I'll throw out the entire batch. (one bad apple....)

And then, I have to force myself not to think about how people making salads for me (ie, at a restaurant) are far less vigilant.
