Aflatoxin M1 in buffalo and cow milk in Afyonkarahisar,Turkey

Potential hazardous human exposure to aflatoxin M₁ (AFM₁) via consumption of milk and milk products has been demonstrated by many researchers. The aim of this study was to investigate the presence of this mycotoxin in buffalo and cow milk samples in the city of Afyonkarahisar, Turkey. For this purpose, 126 buffalo and 124 cow milk samples were collected from dairy farms in Afyonkarahisar province. AFM₁ levels were determined by high-performance liquid chromatography with tandem mass spectrometric detection. Although AFM₁ was not detected in cow milk samples, AFM₁ was found above the limit of detection (<0.008–0.032 µg/L) in 27% (34 out of 126) of the buffalo milk samples. The results of this study indicated the importance of continuous surveillance of commonly consumed milk or milk product samples for AFM₁ contamination in Turkey.
