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

金黃色葡萄球菌(Staphylococcus aureus)是一種重要病原菌,隸屬于葡萄球菌屬(Staphylococcus),是革蘭氏陽性菌的代表,可引起許多嚴重感染,也是常見的食源性致病菌,一旦食物保存不當,金黃色葡萄球菌可大量繁殖,可引起食物中毒。(剩余4084字)
