A survey on the occurrence of aflatoxin M 1 (AFM 1 ) was carried out in summer and winter in raw milk samples from 93 traditional and industrial dairy farms of the Hamedan district in order to address representative data on AFM 1 in milk collected from these regions. Of the 186 milk samples, AFM 1 was detected in 119 samples (63.97%). The mean concentration of AFM 1 in contaminated samples was 43.4 ng/L, and the minimum and maximum levels were ≤ 10 and 410 ng/L, respectively. Fourteen (11.76%) contaminated samples had AFM 1 in concentrations in excess of the maximum levels specified in European Union regulations, i.e., 50 ng/L. The contamination ratio of milk in summer and winter months was 56.5 and 71.7%, respectively ( P < 0.02). This is the first report on AFM 1 determinations in raw milk from western Iran, one of the main milk‐production areas, as well as comparison between milk obtained from different dairy farms in Iran.
