Aflatoxin M (AFM) and aflatoxin B (AFB) were determined in 51 milk powder samples purchased from different grocery stores located in the Caribbean region of Colombia. Analysis was conducted using QuEChERS extraction and high-performance liquid chromatography with fluorescence detection. Results from the analytical method showed recovery ranges from 65% to 110% and relative standard deviations lower than 20%. AFM was detected in 100% of the milk samples (0.20-1.19 µg/kg) and 55% exceeded the maximum level in milk (0.5 µg/kg) set by the Colombian and European regulations. AFB was not detected in any of the analysed samples. Considering the measured contamination the maximum AFM level that can be ingested by consumption of milk powder is 0.007-0.013 µg/person/day. These values are above the average dietary intake estimated in Latin America according to the Joint FAO/WHO Expert Committee, which is 0.0035 µg/person/day.
在哥伦比亚加勒比地区的不同杂货店购买的 51 个奶粉样本中，检测了黄曲霉毒素 M（AFM）和黄曲霉毒素 B（AFB）。使用 QuEChERS 提取和高效液相色谱法与荧光检测进行分析。分析方法的结果显示回收率范围在 65%至 110%之间，相对标准偏差低于 20%。100%的牛奶样本中检测到 AFM（0.20-1.19μg/kg），55%的样本超过了哥伦比亚和欧洲法规规定的牛奶中最高限量（0.5μg/kg）。在分析的样本中均未检测到 AFB。考虑到所测量的污染程度，通过食用奶粉摄入的最大 AFM 水平为 0.007-0.013μg/人/天。这些值高于根据粮农组织/世卫组织联合专家委员会估计的拉丁美洲的平均膳食摄入量，即 0.0035μg/人/天。
