食品安全快速检测技术存在问题分析及解决措施

Problems analysis in food safety rapid detection and the solutions

食品快速检测方法因其快速、简便、成本低廉、适用性广的特点,在我国食品安全领域有着广泛的应用,已成为基层食品药品监管部门日常进行大范围监测和筛查的重要监管手段。伴随着快检需求的迅猛增长,快检方法假阳性与假阴性率高、特异性不强、灵敏度低等多种问题日渐凸显,制约了快检技术在我国食品安全管理中的应用。本文针对问题产生的原因展开系统分析,寻求解决问题的方法。提出食品快检技术应同常规实验室检测一样,选择可靠的快检产品,依靠完善的质量控制体系,并对质量控制方式进行了阐述,进而探讨了提高食品快速检测结果准确性和可靠性的方法。

Rapid detection for food safety is extensively used in food field due to its superior characteristics of rapid detection, easy operation, low costs, wide applicability, etc. It has become the important method of supervision and high-range monitoring for grass-roots food and drug administration. With the sharply rising demand for rapid detection, the problems such as high false positive/negative rate, low specificity and sensitivity, are gradually highlighted. It has affected the management of food safety. This paper analyzed causes of the problems above, and elaborated some solutions. It was proposed that as well as the conventional laboratories, rapid detection should depend on perfect quality control system. Therefore, reliable products should be selected and quality control measures should be taken in food rapid detection. This paper also explained the methods for quality control, and discussed a reliable way to improve accuracy of detection results.
