Aflatoxins are potent carcinogenic, mutagenic and teratogenic metaboli
tes produced by molds that grow on food and feed. Their toxicity has c
aused severe health and economic problems worldwide. Human exposure to
aflatoxins can arise from the direct consumption of contaminated comm
odities such as corn (maize), peanuts or figs, or from the consumption
of foods from animals previously exposed to aflatoxin in feeds (milk
and egg products). Food safety monitoring programs for aflatoxins have
been established for raw and finished products; these include establi
shment of regulatory limits or guidelines, monitoring programs for afl
atoxin levels in susceptible products, and decontamination procedures
and/or the diversion of contaminated products to lower-risk uses.
