Mycotoxins are one the most important issues of human health. One of the most important ways to transfer of these toxins in to human diet is through animal product. Because of this, investigation on the fungal contamination of animals feed which are the main sources of mycotoxins has been taken special importance. The present study evaluated 40 dairy cattle and 35 beef cattle feed samples for fungal contamination in central province of Iran, Arak. The samples were taken from five commercial distributors of animal feed. Five feed samples of beef cattle (35 samples totally) and eight feed samples of dairy (40 samples totally) were selected from these distributes. Dichloran-Glycerol (DG18) selective medium was used in the present study. The results showed the fungal contamination of feeds in dairy feeds samples was 37.5% (15/40) and it was 37.1% (13/35) in beef cattle feeds. The average values for fungal contamination for dairy feeds and beef feeds were 3.63 and 3.52 CFU/g respectively. The results clear that the high rates of fungal contamination of dairy and beef cattle feeds might be as important health concerning issues in the research area and more studies are granted to minimize this contamination in animal nutrition and consequently in human health.
