    Abstract:
    Aflatoxin M1 (AFM1) is a 2B Group human carcinogens agent and introduces into the human diet by milk consumption. In the present study 257 raw, 143 pasteurized and 61 UHT milk samples were collected from markets in 117 cities throughout Iran, during winter 2017 and AFM1 contents were determined using a HPLC-FLD method after immunoaffinity clean-up. Mean recovery rates and relative standard deviations of the method were 90.6 ± 5.7%. AFM1 was detected in 252 of 461 (54.7%) samples (mean 31.3 ± 8.8 ng/L), ranging from <10 to 150 ng/L. Three samples (0.6%) exceeded the Iranian maximum limit of 100 ng/L. The mean AFM1 content was significantly higher in raw milk samples obtained from humid climate areas. The extrapolated concentration of AFB1 in dairy cattle feed based on the AFM1 value of milk was 1.96 µg/kg. The AFM1 contamination of milk seems not to be a serious public health concern in Iran.
