【摘要】 目的:了解常熟市市场上动物源性食品中喹乙醇、喹恶啉-2-羧酸、3-甲基-喹恶啉-2-羧酸残留情况。方法:2019—2021年,在常熟市各大超市、农贸市场采集各类动物源性食品,采用高效液相色谱-串联质谱法进行检测。结果:喹乙醇在猪肉、鱼肉、鸡肉、牛肉、猪肝和猪肾中均未检出;喹恶啉-2-羧酸在猪肉、鱼肉和牛肉中未检出,在鸡肉中的检出浓度为2.5 μg·kg^-1,检出率为3.3%,在猪肝中的检出浓度为4.8～21.3 μg·kg^-1,检出率为10%,在猪肾中的检出浓度为2.7～6.2 μg·kg^-1,检出率为6.7%;3-甲基-喹恶啉-2-羧酸在鱼肉和牛肉中未检出,在猪肉中的检出浓度为1.7～3.2 μg·kg^-1,检出率为4%,在鸡肉中检出浓度为1.1 μg·kg^-1,检出率为3.3%,在猪肝中的检出浓度为5.6～30.8 μg·kg^-1,检出率为16.7%,在猪肾中的检出浓度为2.9～10.7 μg·kg^-1,检出率为6.7%。结论常熟市市场上销售的动物源性食品中喹恶啉-2-羧酸、3-甲基-喹恶啉-2-羧酸残留具有一定的风险,尤其是内脏中残留较为严重,需要监管部门加大监管力度,引导市民尽量少食内脏,保证食品安全,保障人民身体健康。更多还原

【Abstract】 Objective:To investigate the residues of olaquindox,quinoxaline-2-carboxylic acid and 3-methylquinoxaline-2-carboxylic acid in animal derived food in Changshu.Methods:From 2019 to 2021,most kinds of animal derived foods were collected from supermarkets and farmers’ markets in Changshu,and detected by high performance liquid chromatography-tandem mass spectrometry.Results:Olaquindox was not detected in pork, fish,chicken,beef,pig liver and pig kidney.Quinoxaline-2-carboxylic acid was not detected in pork,fish and beef,but the detection concentration was2.5 μg·kg^-1 in chicken,4.8～213 μg·kg^-1 in pig liver,2.7～6.2μg·kg^-1 in pig kidney,and thedetection ratewas 33% in chicken,10% in pig liver,6.7% in pig kidney.3-methyl-quinoxaline-2-carboxylic acid was not detected in fish and beef,but the detection concentration was 1.7～3.2μg·kg^-1 in pork,1.1 μg·kg^-1 in chicken,5.6～30.8 μg·kg^-1 in pig liver,2.9～10.7 μg·kg^-1in pig kidney;the detection rate was 4% in pork,3.3% in chicken,16.7% in pig liver,6.7% in pig kidney.Conclusion:There are certain risks of olaquindox,quinoxaline-2-carboxylic acid and 3-methyl-quinoxaline-2-carboxylic acid residues in animal derived food sold in Changshu market,especially in viscera.Regulatory authorities need to strengthen supervision to guide citizens to eat less viscera,ensure food safety and protect people’ s health.更多还原
