摘要
目的通过对某邮轮诺如病毒感染相关专题调研,发现诺如病毒感染相关的危险因素,以进行针对性改进,降低邮轮群体性诺如病毒感染事件的发生风险。方法通过4个航次的诺如病毒专题随船调研,采用查看工作记录、现场询问、快速检测等手段,采用HACCP体系对食品采购、贮存、加工、供餐、饮用水供应、卫生处理、疫情处置等方面做全面的危险分析,根据结果确定关键点,提出控制措施建议。结果该邮轮在食品采购、贮存、加工和供应,饮用水供应,卫生处理,疫情处置方面都发现了一些问题和风险并提出了控制措施。其中蔬菜样本中检测出诺如病毒是最大的危险点,提示其蔬菜供应和加工环节特别需要采取控制措施。结论通过有针对性的专题调研,利用HACCP原理对诺如病毒感染危险因素进行了针对性改善,降低了群体性感染事件的发生风险。
