They are secondary metabolites which considered as one of the threatening factors of food and feed consumer health. In this study the possible presence of aflatoxins (B , B , G , G2 and total aflatoxin) in rice bran were 121 evaluated. In order to determine of aflatoxins and contamination of the samples with toxigenic fungi, especially A. flavus and A. parasiticus, 30 rice bran samples were collected from different factories in Mazandran province, northern Iran. Samples containing 15 specimens were conserved for one year in the storage and the other one was not subjected to storage. Aflatoxins were extracted, purified and finally quantified by high performance liquid Chromatography (HPLC). Results showed that almost all collected samples contained aflatoxins. The averages of total aflatoxins in new and old rice bran were found to be 18 and 17 µg/kg, respectively. No significant difference was obtained between total aflatoxin rate in new and old samples. The correlation between culture results and aflatoxins production were significantly observed only in old samples (P<0.05). The most common isolated fungi were Aspergillus spp, Fusarium spp, Mucor spp and Rizopus spp. These results confirmed that under study bran rice were contaminated with aflatoxins and different toxigenic fungi. So animals, especially ruminants, are in danger to be affected by contaminated feeds.Read More
