At the same time the veterinary drug residual laws (negative, positive rate is not exceeded, the positive standard rate) was analyzed. The results showed that the amount of Chloramphenicol three days before slaughter and slaughter exceeded the rates prevailing positive is 1.76% and 0.71% respectively ;The amount of Nitrofurantoin three days before slaughter and slaughter date exceeded the rate of positive is 1.32% and 0.35% respectively; The amount of Nitrofurazone three days before slaughter and exceeded the rate of positive slaughter date is 0.88% and 0.36%; The amount of Furazolidone three days before slaughter and slaughter date exceeded the rate of positive is 1.32% and 0.71% respectively; The amount of Furaltadone three days before slaughter and slaughter exceeded the rate of the day were positive 0.44% and 0; The amount of Sulfaquinoxalinum three days before slaughter and slaughter date exceeded the rate of positive is 0.88% and 0.33% respectively. It can be seen that fresh duck in Shandong region are still have security issues. Measures should be taken to strengthen monitoring.Key words: fresh duck meat ; veterinary drug residue ; detection ; analysis0.引言0.1立题背景及依据0.1.1兽药残留概述随着经济的发展，动物性食品在人们日常生活中所占的比重越来越大，人们对食品的要求已不单纯是高蛋白、低脂肪等合理丰富的营养内容，而且现在食品卫生安全也
