Abstract: Proficiency testing is an important method to evaluate laboratory calibration or testing ability by using inter-laboratory comparison. Reasonable quality control is the key to ensure the accuracy of proficiency testing test results. In this paper, the influencing factors and key links of proficiency testing for quantitative detection of Staphylococcus aureus in food are analyzed from five aspects: reagent consumables, operation process, equipment, personnel, and environment, so as to provide reference for the quality control of food microbiology laboratory proficiency testing.
Keywords: Staphylococcus aureus; proficiency testing; quality control
金黄色葡萄球菌(Staphylococcus aureus)是一种重要病原菌,隶属于葡萄球菌属(Staphylococcus),是革兰氏阳性菌的代表,可引起许多严重感染,也是常见的食源性致病菌,一旦食物保存不当,金黄色葡萄球菌可大量繁殖,可引起食物中毒。(剩余4084字)
