I'd say that eating moldy foods is substantially similar to eating wild mushrooms.

If you can't identify the mold species with certainty, don't.

This article didn't do much to answer the question, quite frankly.

"News" articles like these are really just pretty thin publicity for TV shows. The intent is to fill some space but mainly to get you interested enough that when you get to the end of the article and realise that it was all an advert, you're invested enough to make plans to watch the programme.

Some quite delicious Cheeses contain mould :)

(although once, many years ago, I did do a blue cheese sauce to a meal, and gave myself and my wife a spectacular night and next day of... ejecta. Never going to forget that experience :( )

If you're travelling and eating in a lot of questionable restaurants, grilled cheese is supposed to be one of the safest things to order. This article seems to agree.

I wonder if rice is fine when it's been fried? Many times I've left out fried rice from a delivery for hours and eaten it later. Hmm.

Rice is one of the few foods that's particularly bad to leave out at room temperature due to B. Cereus causing Fried Rice Syndrome: http://en.wikipedia.org/wiki/Bacillus_cereus

I think this was a pretty good article. It walked through a list of common food items and told how safe they were to eat when old.

Seems to me most people are waaay too paranoid about this kind of thing. Refrigerators are a recent innovation.

This is a bad article. I gives very few rules, and even less resources to find out more.
