食品中微生物检测能力验证结果与分析

目的提高实验室检验人员微生物检测能力和水平,增强实验室竞争力。方法实验室参加中国检验检疫科学研究院测试评价中心组织的食品中单核细胞增生李斯特氏菌、副溶血性弧菌2项检验能力验证。按照盲样作业指导书的要求对样品进行前处理后,依据GB4789.30-2016《食品安全国家标准食品微生物学检验单核细胞增生李斯特氏菌检验》和GB 4789.7-2013《食品安全国家标准食品微生物学检验副溶血性弧菌检验》进行定性检测。结果样品17-P842鉴定出单核细胞增生李斯特氏菌,样品18-E886鉴定出副溶血性弧菌。结论本次能力验证结果满意,为今后实验室检测实际样品提供参考经验。

Validation results and analysis of microbial testing capability in food

Objective To improve the ability and level of microbiological testing and enhance the competitiveness of laboratory. Methods The laboratory participated in the ability verification of Listeria monocytogenes and Vibrio parahaemolyticus in foods organized by the testing and evaluation center of Chinese Academy of Inspection and Quarantine. The samples were pre-treated according to the requirements of the blind sample operating instructions, and the qualitative test was conducted according to GB 4789.30-2016 National food safety standard- Food microbiology test-Listeria monocytogenes test and GB 4789.7-2013 National food safety standard-Food microbiology test-Vibrio parahaemolyticus test. Results Listeria monocytogenes was identified in sample 17-P842, and Vibrio parahaemolyticus was identified in sample 18-E886. Conclusion The results of this capability verification is satisfactory, which provides reference experience for future laboratory testing of actual samples.
