Analysis of the capability verification results of microorganism detection on food

目的为客观反映实验室的检测能力和检测技术水平,保证实验室检验结果的准确性和可比性,及时发现和纠正自身存在的问题,达到实验室检测工作持续改进的目的。方法依据国家标准GB/T 4789.6—2003、GB/T 4789.11—2003、GB/T 4789.14—2003、GB/T 4789.9—2008、GB/T 4789.36—2008、GB 4789.2—2010、GB 4789.3—2010、GB 4789.4—2010、GB 4789.10—2010、GB 4789.15—2010、GB 4789.30—2010、GB 4789.40—2010、GB 4789.7—2013和能力验证说明书进行样品处理和检验。结果 2014年本实验室共参加14次能力验证活动,能力验证满意率为92.86%(13/14),其中定性检测项目满意率为100.0%(8/8),定量检测项目满意率为83.33%(5/6)。结论本实验室2014年能力验证中定性检测项目取得满意结果,定量检测项目能力验证结果虽然能够满足食品资质认证的要求,但有待进一步提高。

Objective In order to objectively reflect the laboratory detection ability and the level of detection technology,and ensure the accuracy of the results of laboratory tests and comparison,to timely find and correct the existing problems,so as to achieve the goal of continuous improvement of the testing in the laboratory. Methods According to the GB / T 4789. 6—2003,GB /T 4789. 11—2003,GB / T 4789. 14—2003,GB / T 4789. 9—2008,GB / T 4789. 36—2008,GB 4789. 2—2010,GB 4789. 3—2010,GB 4789. 4—2010,GB 4789. 10—2010,GB 4789. 15—2010,GB 4789. 30—2010,GB 4789. 40—2010,GB 4789. 7—2013 and capacity verification instructions,to handle and inspect the samples. Results In 2014,this laboratory participated in a total of 14 capacity verification activities,with the satisfactory rate of capacity verification of 92. 86%（ 13 /14）. The satisfaction rate of qualitative detection project was 100. 0%（ 8 /8）,and that of the quantitative detection project was 83. 33%（ 5 /6）. Conclusion In the capacity verification of this laboratory in 2014,the qualitative detection project achieved satisfactory results,and though the quantitative detection project can meet the requirements of qualification certification in food,but it remains to be further improved.
