Comprehensive contamination control and treatment of agricultural foods would be vital to the human and domestic animals’ health. Teratogenic and hepatotoxic effects of aflatoxin are important, especially on the mentioned animals because of their inevitable roles in the lives of the human beings. Several studies have been carried out to assess the rate of contamination with AFT among many products as well as the performance of control methods to remove this dangerous alloy, one of which was performed by Mazaheri between 2006 to 2007 that was similar to the present study. She enrolled 71 rice samples in her study and detected AFT (B1, B2, G1 and G2) contamination in 59 cases. Through the mentioned study she reported the most rate of contamination for AFB1,followed by the equal rates for the others whichnare in agreement with our study except for AFG1 and AFG2 which have not been detected in our samples. One probable reason for this difference seems to be the origin of rice samples. In spite of worldwide investigations about aflatoxin contamination and aflatoxin detoxification of other grains such as maize and wheat, little was known about rice as a main food of Iranian particularly in Iran. Therefore specific attempts have been made to find a way against aflatoxin as an important health hazard.
