中文摘要：黄曲霉毒素M１是一种全球最常见的天然有毒物质。由哺乳动物饮食中存在的黄曲霉毒素B１代谢而来。本研究中，总共调查了84个奶样，其中63个（75%）检测到了黄曲霉毒素M1。有机和传统生产的牛奶样品间没有差异(0.021 vs. 0.018 µg/kg; p > 0.05)。巴氏消毒奶与鲜奶样品间也没有差异(0.018 vs. 0.020 µg/kg; p > 0.05)。所有样品的黄曲霉毒素M1含量都不超过巴西法规允许的上限(0.5 µg/kg液体奶)。还评估了估计的每天通过消费有机和传统生产的牛奶摄入的黄曲霉毒素M1含量（EDI）。本研究中黄曲霉毒素M1的EDI值不会对人构成毒理学风险。据悉，这是首次报道巴西有机奶中黄曲霉毒素M1的含量。
外文摘要：Aflatoxin M1 is one of the most common toxic natural substances found worldwide. It metabolizes from aflatoxin B1 that is present in the diet of mammals. In this study, 84 milk samples were investigated in total, and 63 (75 %) were contaminated with aflatoxin M1 above the limit of detection. No difference was observed between the samples from organic and conventional systems (0.021 vs. 0.018 µg/kg; p > 0.05). There was no difference between pasteurized and raw milk samples (0.018 vs. 0.020 µg/kg; p > 0.05). None of the samples contained aflatoxin M1 above the maximum level permitted by Brazilian Legislation (0.5 µg/kg for fluid milk). The estimated daily intake (EDI) of aflatoxin M1 through organic and conventional milk consumption was also evaluated. In this study, the EDI-values for aflatoxin M1 did not pose a toxicological risk for the population. To our best knowledge, this is the first report on aflatoxin M1 levels in organic milk from Brazil.
