Aflatoxins are toxic secondary metabolites wh ich are rarely produced by species of mou Ids belonging to the genus Aspergillus. These moulds grow on stored plant foods, in particular peanuts, wheat and corn. In tropical countries an estimated 25% or more of the food may be contaminated with aflatoxins (Raven et al 1992).
