|Abstract:||One hundred and fifty-two samples of pasteurized milk, powdered milk, cheese and yoghurt, marketed in Campinas, Brazil in 1989-1990, were analysed for aflatoxin M1 by the AOAC TLC method (visual quantitation) 980.21. Fifty-two pasteurized milk samples were also analysed in 1992 by the AOAC HPLC method 986.16. Aflatoxin M1 was not detected in the 1989-1990 samples. Four milk samples of the 1992 batch were contaminated at 73-370 ng/1. Except for the sample with 370 ng/l, which would have been also found positive by the TLC method, the detection of aflatoxin M1 in 1992 reflects the higher sensitivity of the HPLC method, not a greater occurrence of the toxin. Contamination of milk and milk products with aflatoxin M1 does not appear to be a serious public health problem in the city of Campinas at the moment.|
