Aside from tasting like shit and inducing some amazing diarrhea, mold in food usually don't do anything if you've consumed it in small quantities. Obviously, if you for some reason decide to eat an entire loaf of bread, or if your immune system is otherwise compromised, you're gonna have a bad time, but it's usually nothing. I've had a couple of demented patients who end up eating some moldy stuff they've "squirreled away". Amazing diarrhea power, but otherwise alright.
