A REVIEW STUDY ON BIOLOGICAL ILL EFFECTS AND HEALTH

Aflatoxins are a group of secondary metabolites produced mainly by Aspergillus flavus and also by Aspergillus parasiticus, that are acutely toxic to warm blooded animals including human beings. Aflatoxin producing species of Aspergillus are quite common and widespread in nature. They can colonise and contaminate grains before harvest or during storage.
