A mycotoxin (from the Greek μύκης mykes, "fungus" and τοξικόν toxikon, "poison")[1][2] is a toxic secondary metabolite produced by organisms of the fungus kingdom[3] and is capable of causing disease and death in both humans and other animals.[4] The term 'mycotoxin' is usually reserved for the toxic chemical products produced by fungi that readily colonize crops.[5] One mold species may produce many different mycotoxins, and several species may produce the same mycotoxin.[6]
