ELI5: Why is blue cheese safe to eat with mould on but other cheeses aren't?
gpt
Many cheeses, such as blue cheese, deliberately use mold to give it distinctive texture and taste, and these molds are selected with human consumption in mind, meaning that these are types of molds that don't produce toxins harmful to humans.

But if you have cheese - any cheese - that grows some random airborne mold from sitting in the back of your fridge too long, you have no idea what kind of mold that is or what effect it would have on your body.
