NATURAL OCCURRENCE OF FUMONISIN B-1 AND ITS COOCCURRENCE WITH AFLATOXIN B-1 IN INDIAN SORGHUM, MAIZE, AND POULTRY FEEDS

A total of 138 samples consisting of 19 rain-affected sorghum, 25 rain -affected maize, 35 normal maize, 44 normal sorghum, and 14 poultry fe ed samples collected from six different places were analyzed for fumon isin B-1 and aflatoxin B-1. All the rain-affected sorghum and maize sa mples were contaminated with fumonisin B-1 in the range 0.07-8 and 0.0 4-65 mg/kg, respectively. On the other hand 26 normal maize samples an d 2 normal sorghum samples were contaminated with fumonisin B-1 at lev els ranging from 0.01 to 5 and 0.15 to 0.51 mg/kg. Fumonisin B-1 conta mination in the poultry feed samples ranged from 0.02 to 0.26 mg/kg. A ll of the rain-affected samples and poultry feed samples were contamin ated with aflatoxin B-1. 20% of normal sorghum and 89% of normal maize samples also contained aflatoxin B-1 in the range of 5-125 and 0.38-1 09 mu g/kg, respectively. This study reports for the first time the na tural co-occurrence of fumonisin B-1 and aflatoxin B-1 in Indian maize and poultry feeds.
