Abstract

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.
