Aflatoxin M1 levels were assessed by Enzyme Linked Immuno Sorbent Assay (ELISA). There was a high incidence of AFM1 (100%), in both raw and pasteurized milk samples. The AFM1 levels in 6.25% of samples were higher than the maximum tolerance limit accepted by European Union (50 ng L-1), while the observed mean of AFM1 was lower than those proposed for European diets. Maximum level of AFM1 in raw and pasteurized samples were 91.8 and 28.5 ng L-1, while minimum levels were 4.3 and 5.1 ng L-1, respectively. The levels of AFM1 in total samples indicated that feeds for cows in this region were contaminated with AFB1 in such a level that appears to be a serious public health problem at the moment. Therefore, there is a need to limit exposure to aflatoxins by imposing regulatory limits.]]>Alborzi, S., B. Pourabbas, M. Rashid and B. Astaneh,200617582584Battacone, G., A. Nudda, A. Cannas, A.C.
