| Abstract: | In this study, 288 milk samples were collected randomly from individual farms in Qazvin province from March to February 2012, Iran. Samples were analysed for Aflatoxin M1 (AFM1) by ELISA; also the Aflatoxin B1 (AFB1) contamination in animal feed was determined at the same time as the sampling of raw milk. One hundred and sixty-three samples (56.59%) were found to contain AFM1 at various levels; the presence of AFM1 was detected in a concentration ranging between 0.01 and 0.22 ppb. In 113 (69.32%) of the 163 milk samples, AFM1 levels were found to be higher than the maximum tolerable limit (0.05 ppb) accepted by the European union/Codex Alimentarius Commission. The mean AFM1 contamination levels in milk in summer and winter were 0.08 and 0.18 ppb, respectively. The AFB1 contamination level in the winter feed (2.27 ± 1.76) was higher than from summer (0.83 ± 0.60) (P < 0.05). |
