【摘要】 目的 基于2020年广州市食品安全风险监测数据、市场监督管理局定期与不定期食品抽检数据以及挖掘到的网络舆情数据等多个数据来源，构建食品安全风险评价模型，对广州市肉制品的食品安全风险进行评价。方法 利用相关分析法与鉴别力分析法进行指标的筛选，并利用层次分析法和熵权法相结合的方式确定指标体系权重，在此基础上使用模糊综合评价法对2020年广州市肉制品食品安全风险进行最终评估。结果 2020年广州市食品安全风险监测的55份肉制品样品中，五氯酚钠的检出率为43.64%，但农兽药残留食品安全指数和重金属平均目标风险系数值均<1；广东省市场监督管理局对肉制品的抽检不合格率为1.85%。综合监测、监督和舆情数据评价得出，2020年广州市肉制品食品安全风险指数为0.247，处于高风险等级。结论 本研究基于多源数据的食品安全风险评价方法不仅可以解决当前食品安全部门间数据不流通的问题，而且能够从多个维度评价食品安全，提高食品安全风险评估效率，为食品安全潜在风险的识别与靶向定位提供科学依据。更多还原

【Abstract】 Objective To construct a food safety risk evaluation model to evaluate the food safety risk of meat products in Guangzhou based on several data sources,including food safety risk surveillance data in Guangzhou City in 2020,regular and irregular food sampling data from the Bureau of Market Supervision and Inspection,and mined internet opinion data. Methods The indicators were screened using correlation analysis and discriminant analysis,and the weights of each indicator were determined by a combination of hierarchical analysis and entropy method. On this basis,a fuzzy comprehensive evaluation method was employed to make a final assessment for the food safety of meat products in Guangzhou City in 2020. Results In 2020,among55 meat product samples monitored by the Guangzhou food safety risk surveillance,the detection rate of sodium pentachlorophenol was 43.64%,but the food safety index of agricultural and veterinary drug residues and the target hazard quotient of heavy metals were both less than 1. In the samples from the Guangdong Provincial Market Supervision Administration,the unqualified rate of meat products was 1.85%. Based on monitoring,supervision,and public opinion data,the food safety risk index of meat products in Guangzhou City in 2020 was 0.247,which was at a high risk level. Conclusion The multi-source data-based food safety risk evaluation system constructed in our study will not only solve the current problem of data non-circulation among food safety departments,but also evaluate food safety from multiple dimensions,thus improve the efficiency of food safety risk assessment and provide a scientific decision basis for the identification and targeting of potential food safety risks.更多还原
