Aflatoxin Contamination in Agricultural Commodities
Journal Title: Indian Journal of Pharmaceutical and Biological Research - Year 2013, Vol 1, Issue 4
Abstract
Aflatoxin is a naturally occurring Mycotoxin produced by Aspergillus flavus and Aspergillus parasiticus. Aspergillus flavus is common and widespread in nature and is most often found when certain grains are grown under stressful conditions such as draught. The mold occurs in soil, decaying vegetation, hay and grains undergoing microbiological deterioration and invades all types of organic substrates whenever and wherever the conditions are favourable for its growth. Favourable conditions include high moisture content and high temperature.The aflatoxin group is comprised of aflatoxin B1,B2,G1 and G2. In addition , aflatoxin M1 (AFM1), a hydroxylated metabolite of AFB1, is excreted in the milk of dairy cows consuming an AFB1-contaminated ration. Aflatoxin B1 a prototype of the aflatoxins, is widely recognized as the most potent hepato carcinogenic compound and along with other certain members of the group, possess additional toxic properties including mutagenicity, tetrogenicity, acute cellular toxicity and it suppresses the immune system. Aflatoxin contamination of food and feed has gained global significance as a result of its deleterious effects on human as well as animal health. The marketability of food products is adversely affected by aflatoxin contamination.
