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. Geotrichum 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). Aflatoxin M1 (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, cow feed samples from various cowsheds are supposed to be evaluated routinely for aflatoxin, and kept away from fungal contamination as much as possible.
