摘要
目的探讨区域性大型活动餐饮安全风险评估指标,建立评价模型,为区域性大型活动接待单位的事先遴选和开展餐饮安全保障工作提供科学依据。方法采用Delphi专家咨询法确定餐饮安全风险评估指标体系以及评价指标的权重;采用综合指数法建立线性风险评估模型。结果 30名咨询专家的平均从业经历为20.63±5.80年,两轮的应答率均为100%,权威系数分别为0.86±0.06和0.89±0.06,Kendall协调系数分别为0.747(χ2=645.518,P<0.01)和0.858(χ2=802.321,P<0.01),均具有统计学意义;确定了餐饮食品安全风险评估一级指标5项、二级指标22项以及各项指标的权重,其中卫生信誉、卫生管理、建筑卫生、硬件设施和采购、加工、贮存、运输环节卫生的平均权重分别为0.93、1.54、1.43、2.06和4.04;建立了线性风险评估模型。结论区域性大型活动餐饮安全保障线性风险评估模型的建立可为餐饮安全保障工作提供科学依据,具有推广应用价值。
Objective To discuss the quantitative risk evaluation indicators and model for catering food safety during territorial large scale activities; in order to find out the key areas for catering food safety health security and provide scientific bases for the selection of reception units in advance. Methods Delphi expert consultation method was used to establish indicator systems for the risk evaluation of catering food safety during the territorial large scale activities; and the weights of indicators were determined. Furthermore, a comprehensive index method was used to establish the linear risk evaluation model, Results The average working years of thirty experts was 20. 63 ± 5.80; the response rates of the two- round consultation from the experts were both 100% ; and the average coefficient of authorities were 0. 86 ± 0. 06 and 0.89 ±0.06. Kendall＇ s coefficients were 0.747 （X^2 =645.518, P〈0.01） and 0.858 （X^2 =802.321, P 〈0.01）, and opinions among experts were consistent. Five first-class indicators and twenty-two second-class indicators for risk evaluating catering food safety, which could seriously influence the territorial large scale activities, were identified. The weights of hygienic credit, hygienic management, architectural hygiene, hardware installations average weight, and hygiene during purchasing, processing, storing and transportation were 0.93, 1.54, 1.43, 2.06 and 4. 04, respectively. Moreover, the linear risk evaluation model was established. Conclusion The establishment of the quantitative risk evaluation model for catering food safety during the territorial large scale activities provided scientific evidence and technical support for securing public health in territorial large scale activities ,and the model was worthy of wide spread.
