食品检验中的随机性与代表性

在食品安全监督抽检工作中,样品的代表性是目的,过程的随机性是手段,随机性与代表性相互依托,相互影响,随机性的选择带来了结果的不确定性。本文通过对食品安全监督抽检工作中实际案例的分析,提出抽样环节和检验环节的随机性因素,及其对检验结论代表性的影响,幵充分阐述了样品实际情况的复杂性。建议对复杂的情况应觃范检验结论的表述,科学严谨地说明产品的实际质量状况。以期为食品抽样检验中实际问题的探讨提供一些思路,对完善食品安全监管工作提供参考。

Randomness and representativeness in food inspection

In the food safety supervision and sampling work, the representativeness of the sample is the purpose, the randomness of the process is the means, and the randomness and the representative are mutually dependent and influence, the choice of randomness brings the uncertainty of the result. This review put forward the random factors of the sampling link and the inspection link, and its influence on the representativeness of the test conclusion through the analysis of the actual cases in the food safety supervision and sampling work, and fully expounded the complexity of the actual situation of the sample. It was recommended that the complex situation should be stated in the specification test conclusions, and the actual quality of the product should be stated scientifically and rigorously, so as to provide some ideas for the discussion of practical problems in food sampling inspection, and provide references for improving food safety supervision.
