目的确保食品中金属污染物检测数据的准确性、可靠性和可比性。方法组织全国31个省级和新疆生产建设兵团的疾病预防控制中心对下发的豆粉或奶粉基质的质控考核样品进行镉和汞的含量测定,并运用国际上通用的“Z比分数”统计法和与FAPAS参考值比较两种方法对镉、汞的检测结果进行分析和评价。结果 31个实验室按时提交检测结果,镉的检测结果回收率为93.8%,合格率为90.6%;汞的检测结果回收率为96.8%,合格率为93.8%;两种元素的检测结果均合格的实验室占90.6%。结论目前全国省级疾病预防控制中心对食品中金属污染物的总体检测水平较高,但个别实验室的检测水平有待提高。
Purpose To ensure the accuracy, reliability and comparability of metal contamination detection data in foods. Methods The disease prevention and control centers of 31 provincial-level and Xinjiang Production and Construction Corps conducted the determination of cadmium and mercury in the quality control samples of soybean flour or milk powder matrixes issued by the National Bureau of Disease Control and Prevention, and used the international common “Z-score ”Statistical methods and compared with the FAPAS reference two methods of cadmium, mercury test results were analyzed and evaluated. Results 31 laboratories submitted test results on time. The recovery rate of cadmium test results was 93.8% with the pass rate of 90.6%. The recovery rate of mercury test results was 96.8% and the pass rate was 93.8%. The test results of both elements were qualified Of laboratories accounted for 90.6%. Conclusion At present, the provincial CDC has a high level of overall detection of metal pollutants in food, but the testing level of individual laboratories needs to be improved.
