摘要
目的建立适用于食品加工用水微生物检测能力验证方案,并进行评价。方法对1 mL菌种水悬液快速冻干制备能力验证样品,按照CNAS-GL03:2006《能力验证样品均匀性和稳定性评价指南》对样品进行均匀性和稳定性检验,并按照预设方案组织一次能力验证。结果按照方案制备的样品均匀性和稳定性符合能力验证要求,参试实验室反馈的测试结果统计符合能力验证结论分布要求。结论建立的能力验证方案可以作为一种方法来测试被监管实验室检测能力或者集团企业验证下属实验室检测能力。
Objective To establish and evaluate the microbial detection capability verification scheme suitable for food processing water.Methods The test sample was prepared by rapid freeze-drying of 1 mL strain aqueous suspension.According to CNAS-GL03:2006 Guidelines for evaluation of uniformity and stability of samples for capability verification,the uniformity and stability of samples were tested,and a capability verification was organized according to the preset scheme.Results The uniformity and stability of the samples prepared according to the scheme met the requirements of capability verification.The test results from the experimental laboratory were statistically consistent with the requirement of ability verification conclusion distribution.Conclusion The established proficiency testing scheme can be used as a method to test the testing capabilities of supervised laboratories or group companies to verify the testing capabilities of subordinate laboratories.
