Popis: Mycotoxins in milk is a public health concern and has to be regularly monitored. The role of milk in human nutrition is well known. The aim of this study was to evaluate aflatoxin M1 (AFM1) contamination in ultra-high-temperature (UHT) milk samples in Tabriz city (Iran) by enzyme-linked immunosorbent assay. Forty-nine UHT milk samples from different supermarkets in Tabriz city were collected during 6 months (July to December 2008). AFM1 was found in 100% of the examined milk samples; 83.67% of the samples had AFM1 greater than the maximum tolerance limit (50 ng/L) accepted by European Union. It can be concluded that AFM1 levels in the samples purchased in Tabriz city appear to be a serious public health problem at the moment and is much higher than some other countries. PRACTICAL APPLICATION Aflatoxins are both acutely and chronically toxic for animals and humans, and can produce dangerous illnesses including acute liver damage, liver cirrhosis, tumor induction, and are also teratogenic. AFM1 is resistant to thermal inactivation; pasteurization, autoclaving and other varieties of food processing procedures are not effective in the reduction of this toxin. The results obtained from this study can be use to decrease the level of AFM1 in milk, dairy cows' feed samples from various cows' herds, and it must be controlled periodically for aflatoxins and kept away from fungal contamination as much as possible.
