2000年,WHO全球食源性感染网络(GFN)(前身为全球沙门菌监测网)建立了外部质量保证系统(EQAS),EQAS是由丹麦国家食品研究所(DTU Food)主办与WHO GFN合作组织的。EQAS鼓励全球实验室参与室间质控监测体系,评估实验室间病原菌鉴定、血清分型、药敏试验监测数据比对结果,以提高实验室对沙门菌等食源性致病菌的监测质量,同时也验证实验室的检测能力,实验室能力验证被看作是实验室提供持续、高质量、可靠的实验结果的重要工 In 2000, the External Quality Assurance System (EQAS) was established by the WHO Global Foodborne Infections Network (GFN) (formerly the Global Salmonella Monitoring Network), which was organized by the Danish Food Research Institute (DTU Food) in collaboration with the WHO GFN of. EQAS encourages global laboratories to participate in the laboratory quality control monitoring system to evaluate the laboratory results of pathogen identification, serotyping and drug susceptibility testing to improve the quality of laboratory surveillance of food-borne pathogens such as Salmonella , But also to verify the laboratory’s testing capabilities, laboratory proficiency testing is seen as laboratory to provide sustained, high quality, reliable experimental results important work
