Assessment of AflatoxinM1 Contamination in UHT Flavored Milk Samples in Karaj, Iran.

This study was carried out to detect the presence of aflatoxin M (AFM) in 30 UHT flavored milk samples in Karaj, Alborz province, Iran. High-performance liquid chromatography (HPLC) was applied to analyze AFM in the samples. The results showed that aflatoxin M was detected in all the UHT flavored milk samples, the AFM concentration ranged from 0.015 to 0.14 µg/L. Also, 10 samples (33.3%) were contaminated with more than 0.05 µg/L of European Union regulations for aflatoxin M. Wherease, according to the proposed Iranian national standard and FDA (0.5 µg/L), none of the samples has not been contaminated more than the maximum AFM concentrations threshold. This is the first report discovering the fact that UHT flavored milk is an important contributor to the dietary intake of AFM in Iran.
