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.
1989 - 1990年在巴西坎皮纳斯市销售的152份巴氏杀菌乳、奶粉、奶酪和酸奶样本，采用AOAC薄层色谱法（目视定量）980.21分析黄曲霉毒素M1。1992年还采用AOAC高效液相色谱法986.16对52份巴氏杀菌乳样本进行了分析。在1989 - 1990年的样本中未检测到黄曲霉毒素M1。1992年批次的4份牛奶样本受到污染，污染水平为73 - 370纳克/升。除了污染水平为370纳克/升的样本（该样本用薄层色谱法也会呈阳性）外，1992年黄曲霉毒素M1的检测反映出高效液相色谱法具有更高的灵敏度，而非该毒素的发生率更高。目前在坎皮纳斯市，牛奶和奶制品受黄曲霉毒素M1污染似乎不是一个严重的公共卫生问题。
