    Abstract:
    During 2016-2017, 156 samples of fresh milk samples were collected from local markets of Karachi, Pakistan and analysed for aflatoxin M1 (AFM1) contamination using ELISA technique. AFM1 was detected in 143 (91.7%) samples, ranged from 20 to 3090 ng L-1 with a mean level of 346.2 ng L-1. In 125 (80.1%) samples, the AFM1 contamination was greater than the maximum limit (ML = 50 ng L-1) set by EU. However, in 51 (32.7%) samples, the AFM1 level was higher than the ML of 500 ng L-1 as assigned by the USA. Statistical analysis showed that the AFM1 level in milk samples from summer was significantly (p < 0.05) higher than that obtained in winter. It was concluded that the AFM1 levels in the tested samples appear to be a serious public health problem. Therefore, immediate measures should be taken and re-evaluation done for the procedures for farming, transportation, refrigeration, and storage for the control of AFM1 level in milk samples.
