AFLATOXIN CONTENT AND NUMBER OF FUNGI IN POULTRY FEEDSTUFFS FROM INDONESIA

The content of aflatoxin and associated fungi was determined in 56 samples, including 34 of corn, 10 of soybean meal, nine of rice bran and three of broken rice, collected from different poultry farms and poultry feedmills situated around Jakarta-Bogor, Indonesia. Ninety-one per cent of the corn samples contained aflatoxins and the total concentration ranged from 22 to 6171-mu-g/kg. With rice bran, 100% of the samples were positive for aflatoxin B1, ranging from 36 to 71-mu-g/kg. No aflatoxin was detected in samples of soybean meal or broken rice. All the samples were contaminated by several fungi (8 x 10(3)-5 x 10(6) cfu/g) and further identification was limited to Aspergillus flavus and A. parasiticus. The dominant species was A. flavus (2 x 10(3)-4 x 10(6) cfu/g in corn samples, 1.0 x 10(3)-1.0 x 10(5) cfu/g in soybean meal, 2 x 10(4)-4.4 x 10(5) cfu/g in rice bran and 2 x 10(4)-6 x 10(4) cfu/g in broken rice). Some of the corn samples also contained A. parasiticus (2 x 10(3)-9.5 x 10(4) cfu/g).
