ELI5: Why is mold acceptable in some foods, such as cheese, but not in anything else?

We're able to enjoy something like blue cheese dressing, but once mold shows up on bread, it's no good. Why is that? Thanks!

Some molds create toxins that are harmful to the human body. The molds that cause many types of cheese (such as the blue cheese dressing you enjoy) do not create the harmful toxins. Mold on many other foods don't necessarily indicate danger just a lack of freshness (fermentation happening, change in taste, texture, etc.) and are perfectly safe to eat but if you have other food options you will likely throw it away because you probably have enough money to not eat moldy bread.
