Mycotoxins are produced by molds that contaminate agricultural commodities either before harvest or during storage. Mycotoxins are active secondary metabolites that may cause toxic reactions. Although there are many species of toxigenic molds, only a few mycotoxins, particularly those affecting cereals such as maize, wheat, barley, oats, and rice are considered to be significant for humans. The effects of some food-borne mycotoxins are acute, symptoms of severe illness appearing very quickly. Se…A variety of Fusarium graminearum molds are shown.
