Aim of dairy industry is to provide high quality milk and milk products suitable for human consumption. Milk quality is determined by two traits: nutritional composition and level of contaminants. Feeds and fodder are the major source of aflatoxin M (AFM) contamination in milk - principal hydroxylated metabolite of aflatoxin B_1 (AFB). Approximately, 0.3 to 6.2 of AFB_i is converted into metabolized AFM_1 and excreted in milk of dairy animals. Use of appropriate toxin binder is considered as the most promising dietary approach for control of AFM1 in milk. In vivo studies conducted by NDDB indicated that supplementation of bentonite reduces AFM_1 by 47 in milk of cows. Daily supplemental cost is less than a rupee per animal, indicating bentonite as cost-effective toxin binder for control of AFM_1 in milk.
