摘要
蜂蜜兽药残留风险评估是根据蜂蜜中各个兽药的残留含量检测值和每种药物的毒理学相关数据等信息,对食用该蜂蜜可能带来的健康风险进行定量评估。由于药物对人体的毒性作用机理复杂,且不同药物间存在相互制约、影响的现象,难以进行全面综合的评估。为了构建蜂蜜兽药残留风险的多因素综合评估模型,将多指标综合评价方法引入到蜂蜜兽药残留风险评估中。首先采用主客观结合的方式计算各个风险评价指标的权重,然后构建基于遗传算法的多指标综合等级评定模型。依据蜂蜜兽药残留全国采样数据建立出蜂蜜安全风险等级划分模型,将我国蜂蜜兽药残留情况划分为四个风险等级。将上述模型与食品安全指数法对比后,表明风险评估模型具有一定可行性。
In order to construct a multi-factor comprehensive evaluation model, a multi-index evaluation method is introduced into the risk assessment of veterinary drug residues in honey. Firstly, the weight of each risk assessment index is calculated by the combination of subjective and objective methods, and then the multi-index comprehensive evaluation method based on genetic algorithm is constructed. According to the national sampling data of veterinary drug residues in honey, the quality and safety risk grade classification model is established, which divides the risk of veterinary drug residues in honey into four risk levels. Compared with the food safety index method, it shows that the risk assessment model is feasible.
