Aflatoxin M1 Contamination in Pasteurized Milk in Mashhad, Iran

The aim of this study was to evaluate aflatoxin M1 (AFM1) contamination in pasteurized milk samples in Mashhad, Iran. One hundred and ten milk samples from different supermarkets were collected during three months in spring and investigated by Enzyme Linked Immuno Sorbent Assay (ELISA). AFM1 was found in 100% of the milk samples. About 5.4% of the samples contained AFM1 greater than the maximum tolerance limit (0.05 g/l) accepted by European Union. There was not a significant difference among the mean value of AFM1 in three months.
