The term used when ingested material is food or feedstuff on which fungus has been growing and producing small amounts of secondary byproducts that have deleterious effects on humans or animals. For example aflatoxin is a mycotoxin produced by Aspergillus flavus when growing on improperly stored foods such as peanuts.

Nerve toxin.

a chemical which is a metabolic product from a fungus

a highly toxic principle produced by molds or fungi

Toxins produced by fungi or bacteria, sometimes present in mouldy or other out-of-condition feeds.

A secondary metabolite that in small concentrations are toxic when introduced. A method of introduction is through eating contaminated food or inhaling air that contains the toxins from a contaminated room or building.

biologic toxin made molds, fungi

any poisonous by-product produced by certain fungi, particularly mold.

Secondary metabolites produced by fungi, which are toxic to human and animals in small quantities. Production of a specific mycotoxin tends to be genus-, species-, or even strain-specific.

Toxic compounds, produced by fungi, that contaminate plants.

Substance produced by mould growing in food or animal feed and causing illness or death when ingested by humans or animals.

Toxin produced by a fungus

a non-enzymatic metabolite produced by a fungus that has toxic effects; especially affecting humans or animals.

Mycotoxin (from Gk. μύκης (mykes, mukos) "fungus") is a toxin produced by an organism of the fungus family, which includes mushrooms, molds and yeasts. Most fungi are aerobic (use oxygen), are found almost everywhere in extremely small quantities because of their spores, and are most commonly microscopically small. They consume organic matter, wherever humidity and temperature are sufficient, indoors or out.
