Occurrence Of Aflatoxin M1 In Milk And Dairy Products Commercialized In Campinas, Brazil

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/l. 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.132169172Brown, C.A., Aflatoxin M in milk (1982) Food Technology in Australia, 34, pp. 228-231Gilbert, J., Shepherd, M.J., Wallwork, M.A., Knowles, M.E., A survey of the occurrence of aflatoxin M1 in UK-produced milk for the period 1981-1983 (1984) Food Additives and Contaminants, 1, pp. 23-28Piva, G., Pietri, A., Galazzi, L., Curto, O., Aflatoxin M1 occurrence in dairy products marketed in Italy (1987) Food Additives and Contaminants, 5, pp. 133-139Sabino, M., Purchio, A., Zorzetto, M.A.P., Variations in the levels of aflatoxin in cow's milk consumed in the city of Sao Paulo, Brazil (1989) Food Additives and Contaminants, 6, pp. 321-326Scott, P.M., Natural poisons (1990) Official Methods of Analysis of the Association of Official Analytical Chemists, 15th Edition, 2, pp. 1184-1213. , edited by K.
