奶粉中沙门氏菌检测能力验证结果与分析

Verification and analysis detection ability of Salmonella in milk powder

目的通过参加国家食品安全风险评估中心奶粉中沙门氏菌检验分型能力验证,验证实验室的检验能力,提高实验室对沙门氏菌的检测水平。方法按照操作说明和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》进行检测。结果2017S-01(002)-1、2017S-01(002)-2、2017S-01(002)-3的结果,分别为检出肠炎沙门氏菌、未检出沙门氏菌和检出斯坦利沙门氏菌。检测准确率达100%,与盲样考核指定菌一致,能力验证结果满意。结论能力验证提高了实验人员检测水平,使实验室在沙门氏菌检测技术上有了很大提高,同时积累了沙门氏菌的检测经验。

Objective To verify the laboratory‘s testing ability and improve the laboratory’s detection level of Salmonella,by the way of participating in the ability verification test and typing of Salmonella in milk powder from National Food Safety Risk Assessment Center.Methods The test was carried out according to the Food Safety National Standard,Food Microbiological Test,Salmonella Test(GB 4789.4-2016).Results As for the samples of 2017 S-01(002)-1,2017 S-01(002)-2,and 2017 S-01(002)-3,we could detect the Salmonella enteritidis,the Salmonella and the Salmonella stanley,respectively.We were satisfied with this ability verification for the reason of 100 percent accuracy dectection rate,according to confirming result from designated bacteria.Conclusion With regard to detection of Salmonella,proficiency testing not only improved the detection level but also accumulated the detection experience.
