Aflatoxin M sub(1) is one of the most common toxic natural substances found worldwide. It metabolizes from aflatoxin B sub(1) 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 M sub(1) above the limit of detection. No difference was observed between the samples from organic and conventional systems (0.021 vs. 0.018 mu g/kg; p > 0.05). There was no difference between pasteurized and raw milk samples (0.018 vs. 0.020 mu g/kg; p > 0.05). None of the samples contained aflatoxin M1 above the maximum level permitted by Brazilian Legislation (0.5 mu g/kg for fluid milk). The estimated daily intake (EDI) of aflatoxin M sub(1) through organic and conventional milk consumption was also evaluated. In this study, the EDI-values for aflatoxin M sub(1) did not pose a toxicological risk for the population. To our best knowledge, this is the first report on aflatoxin M sub(1) levels in organic milk from Brazil.
