目的了解南通市售食品中铅、镉、汞、铝污染现状,为建立食品污染物的控制和监测管理体系提供科学依据。方法在全市监测点抽取粮食、水产品、肉类、蔬菜、奶类、蛋类等共355份样品进行铅、镉、汞的监测,对面制品、油炸食品、膨化食品共68份进行铝的监测。结果市售食品样品中,铅、镉、汞超标率分别是3.24%(11/339)、5.63%(20/355)、5.22%(14/268)、铝超标率30.88%(21/68)。除藻类、茶叶外,其余各类食品铅、镉、汞均有不同程度超标,超标率最高的食品分别是禽畜肝脏(17.65%)、禽畜肾脏(36.36%)、粮食(24.00%),油炸食品中铝超标率达55.56%。结论要控制食品中重金属和铝的污染,必须从治理环境入手,同时要进一步加强食品安全监管力度。
Objective To understand the status quo of lead, cadmium, mercury and aluminum pollution in Nantong food and to provide a scientific basis for establishing a control and monitoring management system for food contaminants. Methods A total of 355 samples of foodstuffs, aquatic products, meat, vegetables, dairy products and eggs were collected from the monitoring points of the city for the monitoring of lead, cadmium and mercury. A total of 68 samples of flour, fried food and puffed food were subjected to aluminum monitor. Results The over-standard rates of lead, cadmium and mercury in commercial food samples were 3.24% (11/339), 5.63% (20/355), 5.22% (14/268) and 30.88% (21/68), respectively. . Except for algae and tea, the lead, cadmium and mercury in all other kinds of food exceeded the standard in varying degrees. The highest over-standard foods were poultry liver (17.65%), livestock kidney (36.36%), grain (24.00%), Aluminum in fried foods exceeded the rate of 55.56%. Conclusion To control the pollution of heavy metals and aluminum in food, we must start from the management environment, at the same time we must further strengthen food safety supervision.
