中文摘要：本研究旨在探索卡塔尔牛奶及乳制品中黄曲霉毒素M1（AFM1）发生的情况。结果表明，尽管卡塔尔市场销售的乳制品AFM1阳性的百分比较高，但依照欧盟的最大限值，并不代表公共卫生问题。
外文摘要：This study was designed to explore the incidence of aflatoxin M1 (AFM1) in milk and dairy products marketed in Qatar. Milk (n=72), yogurt (n=21), cheese (n=46), butter (n=18) and laban (n=25) samples were initially screened by competitive enzyme linked immunosorbent assay (ELISA) for the presence of AFM1, followed by confirmation with ultra-high-performance liquid chromatography (UHPLC). AFM1 was detected in 85%, 76%, 85%, 67% and 76% of the milk, yogurt, cheese, butter and laban samples, respectively. The levels of AFM1 in pasteurized vs ultra-high temperature (UHT) milk and full- vs low-fat yogurts showed a non-significant difference. Halloumi and Kashkaval cheese varieties showed a significantly higher AFM1 contents as compared to Mozzarella, Edam, Cheddar, cream and Moshalal cheese. Likewise, unsalted butter demonstrated significantly (p<0.05) higher AFM1 values than salted butter samples. None of the tested samples presented AFM1 levels above the EU maximum limits of 50 ng/L or kg for milk, yogurt and butter, and 250 ng/kg for cheese. From the finding of present study, it can be concluded that, although high percentage of dairy products marketed in Qatar demonstrated AFM1 contents, but do not represent a public health concern considering the EU maximum limits.
