Abstract

Fifty four samples including 5 of broken rice, 8 of corn grains, 8 of corn gluten feed, 13 of cottonseed cake and 4 each of rice polish, corn gluten, sesame oil cake, guar meal and wheat bran were screened for the presence of aflatoxins. Among all the samples, 14 were damaged and 40 apparently undamaged. The incidende of aflatoxins was found to be 60, 25, 25, and 23 per cent in broken rice, corn grains, corn gluten feed and cottonseed cake. Aflatoxins were not detected from rice polish, corn gluten, sesame oil cake, guar meal and wheat bran. Damaged sample revealed a much higher incidence i.e. 50 per cent as compared to undamaged ones i.e. 7.5 per cent. Mean concentration of aflatoxin B and G was found to be 15.5 and 12.2 ppb respectively.
