中文摘要:

      目的 分析实验室对巧克力中沙门氏菌检测能力验证实验与结果。方法 依据GB 4789.4-2016《食品安全国家标准 食品微生物学检验 沙门氏菌检验》对巧克力样品进行沙门氏菌检测。参照能力验证计划参试指导书来进行测定和结果判断。结果 通过平板法结合生化鉴定实验结果可知, 编号CODE:384有可疑目标菌落检出沙门氏菌阳性菌, CODE:544、CODE:699的可疑目标菌落均未检出沙门氏菌阳性菌。结论 本次实验室对巧克力中沙门氏菌检测能力验证结果合格, 为提高相关微生物实验室的检测能力提供参考。

英文摘要:

      Objective To analyze the ability verification experiments and results of Salmonella in chocolate of the laboratory. Methods According to GB 4789.4-2016 National food safety standards-Food microbiology inspection-Salmonella, the Salmonella of chocolate samples were detected. Reference ability verification plan guidance book was used for determination and result judgment. Results According to the results of plate method combined with biochemical identification experiment, Salmonella positive bacteria were detected in suspicious target colonies in CODE:384, and no Salmonella positive bacteria were detected in suspicious target colonies in CODE:544 and CODE:699. Conclusion The test results of Salmonella in chocolate of the laboratory are qualified, and this provides reference for improving the detection ability of microbiology laboratory.
