    摘要:

    为更好地进行畜禽产品中微生物风险监管,构建一套覆盖畜禽产品全生产链的微生物风险监测评估和预警系统成为迫切需求。针对畜禽养殖、屠宰生产、储存和流通销售等环节,以肉蛋奶中常见微生物监测数据为基础,通过微生物风险评估模型和数学运算以及预警阈值和预警方法,结合BP神经网络等计算机软件开发技术,构建了一套涵盖基础数据库、风险评估模型和风险预警决策三大模块,面向企业、监管和技术机构三类用户的可视化风险评估预警系统,以期利用该系统对畜禽产品中致病微生物对产品安全性的影响和生产链中风险关键控制点进行分析,同时对畜禽产品中微生物风险状况进行实时预警,从而为畜禽产品质量安全有效监管和风险防控能力提升提供技术支撑。

    Abstract:

    In order to better regulate the risk of microorganisms in livestock and poultry products,and to construct a microbial risk surveillance,evaluation and early warning system covering the whole production chain of livestock and poultry products,based on the surveillance data of common microorganisms in meat,eggs and milk,and aiming at the processes of breeding,slaughtering,storage,movement and distribution,a visual system including general database,risk assessment models and decision-making of early warning was constructed for enterprises and institutions responsible for supervision and technology by means of microbial risk assessment models,mathematical calculation,thresholds and methods of early warning and in combination with BP neural network and other software. The system could be expected to be used for analysis on the influence of pathogenic microorganisms in livestock and poultry products as well as key risk control points along production chain,and for real-time early warning of relevant risk status,which could provide technical support for effective supervision of product quality and safety as well as improvement of capacity of risk prevention and control.
