目的分析存在孔雀石绿残留风险的出口水产品,确定出口水产品中孔雀石绿残留状况及相对严重程度。方法应用层次分析法食品安全预警理论,建立数学模型对汕头出口水产品中孔雀石绿残留进行风险评价。结果综合考虑检出率和检出构成比,存在孔雀石绿药物残留风险的10种出口水产品中,金鲳鱼、鲈鱼风险程度最大,其权值>0.2;其次为甘鱼、冻生鱼片、包公鱼3种,权值在0.1左右;其余罗非鱼、真鲷鱼、鳗鱼、美国红鱼、黑鲷鱼5种鱼风险程度相对较轻,权值在0.03～0.05之间。结论该数学模型可以综合多个评判指标,对出口风险相对严重的做出比较全面的评价,有利于实施适宜的风险监管措施。
Objective To analyze the export aquatic products with the risk of residual malachite green and determine the residual status and relative severity of malachite green in the exported aquatic products. Methods Applying analytic hierarchy process (AHP) theory of food safety early warning, the mathematical model was established to evaluate the risk of malachite green residue in Shantou export aquatic products. Results Among the 10 kinds of exported aquatic products with the risk of residual malachite green drug, the risk of goldfish and perch was the highest with the weight of> 0.2 after considering the detection rate and the detected constituent ratio. There are three kinds of fish with the weight of 0.1 or so. The remaining fish of tilapia, sea bream, eel, American redfish and black snapper are relatively less risky with a weight of 0.03-0.05. Conclusion The mathematical model can synthesize multiple indicators to evaluate the relative risk of exports to make a more comprehensive assessment is conducive to the implementation of appropriate risk control measures.
