Mycotoxins are poisons produced by some members of the fungi kingdom.  (i.e. “eating a poison mushroom can make you sick.”)  You may have heard of the term “mycotoxins” because it often gets mentioned in articles about mold, as mold is a member of the fungi kingdom.  Mycotoxins produced by mold are what set off allergic reactions to mold in some people. Since almost all types of mold produce mycotoxins that can cause allergies in certain people who are sensitive, serious mold professionals are trying to move away from the focus on black mold, and move toward the mantra that “no mold, no matter what color, belongs in a healthy home.”
