Mycotoxin

A mycotoxin (from the Greek μύκης mykes, "fungus" and τοξικός toxikos, "poisonous") is a toxic secondary metabolite produced by fungi and is capable of causing disease and death in both humans and other animals. The term 'mycotoxin' is usually reserved for the toxic chemical products produced by fungi that readily colonize crops.

Examples of mycotoxins causing human and animal illness include aflatoxin, citrinin, fumonisins, ochratoxin A, patulin, trichothecenes, zearalenone, and ergot alkaloids such as ergotamine.

One mold species may produce many different mycotoxins, and several species may produce the same mycotoxin.
