Abstract

This survey was conducted to determine the occurrence and levels of aflatoxin M-1 (AFM(1)) in 250 breast milk samples of lactating mothers, obtained from urban and rural regions of Shahrekord, Iran. Moreover, the association between AFM(1) occurrence levels and dietary factors was assessed. AFM(1) analysis was carried out using the competitive enzyme-linked immunosorbent assay technique for screening and high-performance liquid chromatography with fluorescence detection (HPLC-FLD) for confirmatory purposes. The toxin was detected in 39 samples (15.6%), ranging from 11.1 to 39.3ng/l, of which 8 samples (3.2%) had levels above the Iranian national standard limit (25ng/l). AFM(1) occurrence and levels in breast milk samples obtained from rural regions were significantly higher (P0.05) than those obtained from urban ones. It might be due to the different dietary patterns in these regions. It was found that dietary habits with more tendencies to consume bread, rice and non-alcoholic beer beverage significantly increased (P0.05) the risk of AFM(1) occurrence in breast milk. In addition, higher consumption of bread, olive and traditional cream significantly increased (P0.05) the levels of AFM(1) in breast milk samples. Further investigations should be performed to determine more precisely the association between AFM(1) occurrence and dietary factors and also the risk of infant exposure to this mycotoxin.
