中文摘要:

      目的 对烟台市动物源性食品中硝基呋喃的污染状况进行调查, 了解烟台市动物源性食品中硝基呋喃的污染情况。方法 采用随机采样的方法, 于2012~2017年于烟台辖区内养殖环节、运输环节、流通环节和餐饮环节, 共采集动物源性食品样本250份, 采用液相色谱-串联质谱法定量检测硝基呋喃类药物残留。 结果 烟台市售动物源性食品中硝基呋喃类药物总检出率为1.6%(4/250)。双壳类和鱼类水产品中有硝基呋喃代谢物检出, 检出率分别为5%(2/40)和2.47%(2/81), 甲壳类水产品、畜肉类、禽肉类和蛋类中硝基呋喃代谢物均未检出。4种硝基呋喃代谢物中3-氨基-2-恶唑烷基酮(3-amino-2-oxazole alkone, AOZ)的检出率最高(1.2%, 3/250)。结论 烟台市动物源性食品中硝基呋喃污染总体较轻, 但在一定程度上存在硝基呋喃的残留, 应加强监督管理, 保障食品安全。

英文摘要:

      Objective To investigate the pollution of nitrofuran in animal derived food in Yantai, and to understand the pollution of nitrofuran in animal derived foods in Yantai. Methods Totally 250 animal derived food samples were collected in Yantai city from breeding section, transport links, intermediate links and catering links during 2012 to 2017 according to the principle of random sampling. The samples were determined by liquid chromatography-tandem mass spectrometry. Results The positive rate of nitrofuran metabolites was 1.6% (4/250). Nitrofurans metabolite was detected in bivalve and fish with the detection rates of 5%(2/40) and 2.47%(2/81), respectively. Nitrofurans metabolite was not detected in crustacea, livestock meat, poultry meat and eggs. The detection rate of 3-amino-2-oxazole alkone (AOZ) was the highest among all metabolites which was 1.2%(3/250). Conclusion The animal derived food in Yantai is slightly polluted by nitrofuran. Some animal derived food is contaminated by nitrofurans. Therefore, supervision and inspection should be strengthened in food production to ensure food safety．
