摘　　要：为了解广西动物源性产品中磺胺二甲嘧啶(SM_2)残留情况,本研究采用磺胺二甲嘧啶化学发光酶免疫分析法(SM_2-CLEIA)对2013—2017年采集的4 637份动物源性产品进行检测,共检出超标样品122份,涉及鲜乳、猪肉、水产品和猪尿,其中超标猪尿92份,SM2含量100.51～860.44μg/kg,猪尿中抗生素残留会污染水体、土壤,再通过动植物的富集作用进入食物链,危害人类健康,应引起重视;而本次受检的水牛奶、鸡肝脏、鸭肝脏、鸭肉均合格。所有受检样品超标率逐年下降,同时规模化养殖场样品合格率高于农村散养户、超市高于农贸市场。不同年份超标样品含量以2014年最高。采用食品安全指数(IFS)对广西动物源性食品中SM_2残留风险进行评估,结果均远小于1,说明在广西地区,现有的SM_2残留对人体的潜在危害较低。To reveal the sulfadimidine(SM 2)residue in main animal-source products in Guangxi,4 637 samples were collected from 2013 to 2017,and were detected by the method of SM 2-CLEIA.A total of 122 samples,involving milk,pork,aquatic product and swine urine,were detected to have SM 2 residue above the national standards,of which 92 were swine urine,with contents ranging from 100.51 to 860.44μg/kg.Antibiotic residues in swine urine could contaminate water and soil,and thus enter the food chain,and their enrichment effects through animals and vegetables would be harmful to human health,which deserved due attention.Samples of buffalo milk,chicken livers,duck livers and duck meat all met standard in the tests.A survey of sources of the 122 samples displayed that the average amount of SM 2 residue was decreasing annually,and that the qualified rates of the samples from intensive livestock farms were higher than those from individual farms,and those from supermakets were higher than those from farm’s markets.The content of SM 2 residue in samples taken in 2014 was the highest over the five years.IFS was employed to evaluate the safety of animal-derived foods in Guangxi,and the results were far less than 1,showing that the potential risk of SM 2 residues to the human body was low in Guangxi.
