中文摘要:

      目的 对基于快检初筛的食用农产品安全抽检模式进行分析, 以充分发挥快检技术的优势, 提高食品抽检靶向命中率。方法 针对食用农产品快检初筛阳性样品启动法定抽检程序, 并采用实验室检测方法进行定量检测, 从而分析基于快检初筛的抽检不合格率。结果 针对快检阳性样品定量抽检72批次, 检出不合格样品33批次, 不合格率为45.8%, 经快检初筛后抽检靶向命中率提高约15倍。其中部分项目抽检靶向命中率偏低, 还需在现场制样、规范操作等环节改进完善。结论 快检技术在提高抽检靶向命中率方面卓有成效, 基于快检初筛进行食品安全抽检模式对降低监管成本、提升监管效能具有重要意义。

英文摘要:

      Objective To analyze the mode of food safety sampling based on rapid screening, so as to give full play to the advantages of rapid screening technology and improve the target hit rate of food sampling. Methods The legal sampling procedure for the positive agricultural products were started through rapid screening, and the laboratory detection method was used to carry out quantitative detection, so as to analyze the unqualified detection rate of positive samples. Results A total of 72 batches of positive samples were spot-checked by rapid inspection, and 33 batches of these samples were unqualified. The total problem detection rate was 45.8%. The target hit rate of spot check was increased about 15 times than that in regular sampling mode after rapid screening. The targeted rates of some detection items were low, which needed the improvement in the course of samples preparation and detection. Conclusion Rapid inspection technology makes target detection rate higher effectively. This new sampling mode based on rapid detection has important role in food surveillance with less cost yet more efficiency.
