Sažetak
Aflatoxin M1 (AFM1), a toxic byproduct of aflatoxin B1 (AFB1) produced by Aspergillus fungi, is a carcinogenic mycotoxin that can contaminate various agricultural commodities. It can be transferred from AFB1-contaminated feed to milk and dairy products, including yogurt, posing a potential health risk to consumers. In spring 2023, a total of 74 yogurt samples were collected from the largest food suppliers in Kosovo for analysis, including samples produced in Kosovo and seven other countries: Albania, North Macedonia, Bosnia and Herzegovina, Slovenia, Greece, Italy, and Germany. A rapid and sensitive analytical method, Enzyme-linked immunosorbent assay (ELISA), was used for the analysis. The results of the study highlight discernible differences in the maximum tolerable levels of AFM1 between the countries. More specifically, yogurt samples from Slovenia and Germany had lower levels than those from other countries. Additionally, the median levels of AFM1 in samples from Slovenia and Germany were significantly lower. The mean concentrations of AFM1 in yogurt samples from Kosovo and other countries were 0.071 μg/kg and 0.080 μg/kg, respectively. Out of all samples, 66 (89%) exceeded the maximum tolerable limit of 0.05 μg/kg. Among the exporting countries, Albania had the highest median AFM1 level of 0.085 μg/kg and the highest maximum level of 0.195 μg/kg. Slovenia had the lowest median AFM1 level, while Germany had the lowest maximum AFM1 level. All samples from Albania, Greece, and Bosnia and Herzegovina exceeded the maximum tolerable limit. High prevalence was also observed in samples from Kosovo, North Macedonia, and Slovenia. Considering the average daily consumption of about 250 grams of yogurt, and the total median value of Aflatoxin M1 concentration (0.071 μg/kg), the estimated daily intake was calculated to be 0.017 μg. These findings highlight the importance of monitoring and enforcing regulatory limits to ensure yogurt safety and to protect public health. Efforts should be focused on mitigating AFM1 contamination and implementing measures to minimise its presence in dairy products, especially in regions where levels exceed the established limits.
