Abstract

This study was carried out to detect the presence of aflatoxin M1 (AFM1) in 30 UHT flavored milk samples in Karaj, Alborz province of Iran. High-performance liquid chromatography (HPLC) was applied to analyse AFM1 in the samples. Result showed that aflatoxin M1 was detected in all the UHT flavored milk samples, the concentration of AFM1 was ranged from 0.015 to 0.14 µg/kg. Also, 10 samples (33.3%) was contaminated with more than 0.05 µg/kg of European Union regulations for aflatoxin M1. While, according to proposed Iranian national standard and FDA (0.5 µg/kg), none of sample has not contaminated more than the maximum tolerable concentrations of AFM1. This is the first report discovering that UHT flavored milk is a important contributor to the dietary intake of AFM1 in Iran.
