中文摘要：黄曲霉毒素B1经动物转化生成黄曲霉毒素M1（AFM1）而成为牛奶的一部分，而重金属则在供应链处理过程中进入牛奶和牛奶制品。黄曲霉毒素M1和重金属是有毒化合物，需要持续监测，避免消费者食用这类毒素污染的食品后感染的任何疾病。本研究对巴基斯坦市场13个品牌婴儿配方奶粉（IFM）进行了分析，分别通过ELISA和原子吸收分光光度计对AFM和重金属进行了定量检测。研究发现测试的一些婴儿配方奶粉（IFM）中AFM1、Zn和Ni水平升高，表明一份完全基于这些IFM品牌的食谱可能对最脆弱的人群，比如婴儿的健康造成严重影响。
外文摘要：Aflatoxin M-1 (AFM(1)) after its bioconversion from aflatoxin B-1 in animal hirer becomes the part of milk while heavy metals get entry into milk and milk products during handling in the supply chain. Aflatoxin M-1 and heavy metals being toxic compounds are needed to be monitored continuously to avoid any ailments among consumers of foods contaminated with such toxicants. Thirteen commercially available infant formula milk (IFM) brands available in Pakistani markets were analyzed for the quantitative determination of AFM, and heavy metals through ELISA and atomic absorption spectrophotometer, respectively. AFM(1) was found positive in 53.84% samples while 30.76% samples were found exceeding the maximum EU limit i.e. 0.025 mu g/kg for AFM(1) in IFM. Heavy metals lead (Pb) and cadmium (Cd) were found below the detection limits in any of the sample, whereas the concentrations of iron (Fe), zinc (Zn) and nickel (Ni) ranged between 45.40-97.10, 29.72-113.50 and <0.001-50.90 mu g/kg, respectively. The concentration of Fe in all the tested brands was found in normal ranges while the concentrations of Zn and Ni were found exceeding the standard norms. Elevated levels of AFM(1), Zn and Ni in some of the tested IFM brands indicated that a diet completely based on these IFM brands might pose severity health implications in the most vulnerable community i.e., infants.
