Aflatoxin M1 in milk in Hisar city, Haryana, India and risk assessment

ABSTRACT

Aflatoxin M1 (AFM1) contamination in 150 samples of milk, sold in market of Hisar city of Haryana, India, was investigated by using High Pressure Liquid Chromatography (HPLC). Out of these, 40 samples contained AFM1 at a concentration below the limit of detection (LOD) of 0.052 μg/kg. Among the AFM1 contaminated samples, 46 raw milk samples contained a concentration above the LOD but less than the limit of quantitation (LOQ), whereas 64 samples were above the LOQ. Of these samples, 31 exceeded the maximum limit of 0.5 μg/kg prescribed by FSSAI, India. Based on this study, the dietary intake of AFM1 for adults through consumption of milk was estimated. The results indicated that AFM1 contamination can be a food safety issue for raw and pasteurised milk consumed in India. Therefore, there is a need for a national monitoring programme to control the level of mycotoxins in milk.
