Popis: Aflatoxin M1 (AFM1) appears in milk or dairy products as a direct result of the cattle's ingestion of feed contaminated with aflatoxin B1 (AFB1). This study comprises mycological and mycotoxicological investigations of 23 milk samples (raw, infant food, pasteurized, whey and yoghurt). The mycological testing showed dominant presence of genus Geotrichum. G. candidum was found in 9 samples, with the highest contamination in the raw milk samples. The contamination level of AM1 is defined by using direct competitive enzyme- -linked immunosorbent assay (ELISA). AFM1 was found in 9 samples. AFM1 levels were lower than the recommended limits. However, as AFM1 is considered a probable human carcinogen (2B type), it is necessary to achieve a low level of AFM1 in milk. Therefore, cows' feed samples from various cowsheds are supposed to be evaluated routinely for aflatoxin, and kept away from fungal contamination as much as possible.
