The term “mold” can be used two ways. There is the generic “mold” that is basically anything you can see growing on anything. Could be fungus, could be bacteria, you don’t know you just know it’s moldy. But, used in a more specific sense, mold refers to fungus. Mycotoxins, more specifically alflatoxins and ochratoxin, are produced by some of those fungi. The usual culprit is Aspergillus flavus, but you can also run into Fusarium and Penicillium species as well.
Aflatoxin you’re stuck with. Ochratoxin can be remedied with decarb. Cryo ethanol extraction seems to limit the amount of carryover of both.
