Fungal toxins especially aflatoxin, receiving increasing attention worldwide because of the hazard it poses in animal and human. Several Aspergillus and Pecnicillium species, which are predominant in nature, contaminate animal feeds. Aflatoxin B1 is a type I human carsinogen, which contaminated animal food, extracted in milk and meat from animals eating mouldy feeds. The general purpose of this study was to determine the most prevalent fungal species that contaminate the animal feeds in Yazd dairy centers. 67 animal food samples were cultured in plates containing Sabourauds dextrose agar with chloramphenicol (SC). A total of 204 colonies from 14 different saprophyte fungi were isolated that Penicillium (19.6%), and Aspergillus flavus (17.6%) were the most prevalence isolated species. Rhizopus species (12%), Cladosporium (11%), Mucor species (8%), and Aspergillus niger (7%) were the other isolated species. However Aspergillus flavus showed a higher prevalence in traditional dairy centers but there was not seen any statistical significant differences between the traditional and industrial dairy centers (2 2.34, P 0.31). There was seen a statistical significant differences between isolation of Penicillium puberulum and the type of dairy centers 2 = 11.3, P 0.004). Keywords: aflatoxin, fungi, animal food.
