Abstract: Aflatoxin contamination caused by Aspergillus flavus and A.parasiticus is considered as the most serious factor influencing food safety concerning human health. Preharvest aflatoxin contamination in the field has been a common problem in certain agricultural products including corn, peanut, cottonseed, pepper and tree nuts. Several factors have been associated with preharvest aflatoxin contamination in various crops. Drought stress along with high temperature is the most major environmental factor related to preharvest aflatoxin contamination. Resistance of host plant could effectively reduce the contamination. Genetic enhancement for resistance to fungi invasion and aflatoxin production as well as diseases and insect pests and tolerance to drought through combination of conventional breeding and molecular biology approaches will be the priority for aflatoxin contamination management. Meanwhile, integrated control of diseases and pests with suitable crop management is also crucial to prevent preharvest aflatoxin contamination.

Key words: Crops, Preharvest aflatoxin contamination, Management
