Abstract Aflatoxin is of particular importance among food contaminants. There are different types of aflatoxin toxins, of which type 1M is important in milk. This toxin can cause digestive and liver disorders, as well as adverse effects on the immune and reproductive systems, and even cause cancer in some cases. This study was designed to investigate the level of contamination of raw milk produced in the religious metropolis of Mashhad in 1403. This is a cross-sectional and applied study on raw milk produced in Mashhad in terms of contamination with aflatoxin 1M. In a descriptive-analytical study, 100 samples were randomly selected from raw milk collected from different areas of Mashhad city at monthly intervals. After centrifuging the samples, the upper part of the centrifuged milk, which contained milk fats, was removed and set aside, and the lower part of the centrifuged milk, which was free of fat, was analyzed using the ELISA method and a special kit manufactured by I r.S Tecna.
