Abstract :
Background: Aflatoxin M1 (AFM1) is a major carcinogenic compound that may be existed in milk and dairy products. This study was aimed to determine the presence of AFM1 in in-dustrial and traditional yogurt samples produced in Iran.
Methods: A total of 80 yogurt samples (40 industrial, 40 traditional) was collected from su-permarkets in Yazd city, Iran. AFM1 content of the selected samples was determined by en-zyme linked immunesorbent assay (ELISA).
Results: Analysis of the data indicated that 96.25% of the yogurt samples were contaminat-ed with AFM1 in concentration levels ranging from ?5 to 91 ng/kg. The AFM1 content of 5% of the samples was higher than the limit accepted by European Union (50 ng/kg). The mean concentration of AFM1 in traditional yogurt (33.6 ng/kg) was significantly (p < 0.05) higher than industrial ones (24.55 ng/kg).
Conclusion: High level of AFM1 contamination of yogurt produced in Iran could be a seri-ous risk for the public health.
