Abstract Aflatoxin is a potent toxin produced by Aspergillus flavus Link:Fr, an opportunistic ear-rot pathogen of maize (Zea mays L. subsp. Mays). Prior to the discovery of aflatoxin, A. flavus was considered a minor pathogen and was not a priority for maize breeders or pathologists. Aflatoxin was discovered in England in 1961 following an epidemic in poultry. By the early 1970s...
