Abstract The occurrence of aflatoxins M1 (AFLAM1) and B1 (AFLAB1) was evaluated in 112 milk samples (whole, skimmed, semi-skimmed—liquids and powders), collected at a local commercial establishment in southern Brazil and Assomada City, Cape Verde. AFLAM1 and AFLAB1 were determined by using high-performance liquid chromatography with fluorescence detection. For the 62 milk samples from 41 supermarkets in the city of Rio Grande, Rio Grande do Sul, 68% were contaminated by AFLAM1 (range, 40–3670 ng L−1) and 16% were contaminated by AFLAB1 (range, 40–600 ng L−1), with contamination found only in liquid milk. Among the 50 samples from Assomada City, AFLAM1 was detected in 76% of the samples (range, 32–2896 ng L−1), at values below the current Brazilian legislation for the maximum permitted level in milk powder (5000 ng L−1) but higher than that recommended by the European Commission.

在阿索马达市（佛得角群岛）和巴西南部消费的奶粉和 UHT 中发现黄曲霉毒素 B 1 和 M 1

摘要 在巴西南部和佛得角阿索马达市的当地商业机构收集的 112 份牛奶样品（全脂、脱脂、半脱脂液体和奶粉）中评估了黄曲霉毒素 M1 (AFLAM1) 和 B1 (AFLAB1) 的含量。AFLAM1 和 AFLAB1 采用高效液相色谱荧光检测法测定。对于来自南里奥格兰德州里奥格兰德市 41 家超市的 62 个牛奶样品，68% 被 AFLAM1（范围，40-3670 ng L−1）污染，16% 被 AFLAB1（范围，40-600 ng L−1)，仅在液态奶中发现污染。在来自阿索马达市的 50 个样本中，在 76% 的样本中检测到 AFLAM1（范围，32-2896 ng L−1），
