Abstract Aim: Utilizing Aspergillus polluted feed causes aflatoxin production, disturbing disordered domestic health, milk and consumers cycle. In this research the relationship of milk aflatoxin M1 and feed fungi flora was studied in Markazi Province.
Materials and methods: In this study the feed composition used in ten grazieries in Markazi Province in years 2009 and 2010 were examined. Isolation, cultivation and identification of feed fungi were done. Also the resulting produced milk aflatoxin M1 was measured using ELISA method.Then the relationship between feed composition, molds and milk aflatoxin were calculated.
Results: Results showed that the most feed composition were zea, cotton and kolza cakes, feed complementary, barley, wheat bran, dried bread, fat powder and alfalfa. The most comon feed pollutants were Aspergillus flavus, A. clavatus and Rhizopus stolonifere. Anuall studies on collected milk from grazieries showed existing aflatoxin M1 in all of them. Statistical analysis of data confirmed a strong correlation between soya and kolsa cakes with Aspergillus molds in feed and milk pollution to aflatoxin.
Conclusion: Control al feed mold pollution is the best method for the prevention of milk and its products bing polluted to aflatoxins that helps to improve community health.
