During the period 1979‐1985, incoming feed ingredients (some of imported origin) for duck diets were screened for their aflatoxin level. As a result. records of aflatoxin data from 533 corn, 88 rice, 136 rice bran, 47 wheat pollard, 207 soya bean meal. 55 copra meal and 166 fish meal samples were obtained. Aflatoxin B 1 was the predominant form, the incidence of samples containing it ranging from 69 to 94%; then accompanied by aflatoxin G 1 , 37 to 81%: by B 2 , 33 to 70%; by G 2 , 13 to 66%. Levels of total aflatoxin > 20 μg kg −1 were most frequently encountered in corn (71%) and copra meal (58%), followed by soya bean meal (20%), wheat pollard (15%), rice bran (12%), fish meal (10%) and rice (4%). Most feed ingredients contained aflatoxins < 100 μg kg −1 except in corn of which 202 samples (38%) had a higher level. Corn is concluded to be the main source of alfatoxin contamination in corn‐based mixed feeds.
