| 摘要: |
| 为评估我国市场上液态奶产品中兽药残留状况，采集2016年和2017年共计150 份超高温(UHT)灭菌乳和50 份巴氏杀菌乳样品。基于ELISA的可视化微阵列芯片技术检测其中氟喹诺酮、四环素、链霉素和林可霉素的兽药残留。结果表明:UHT灭菌乳样品中氟喹诺酮、四环素、链霉素和林可霉素的检出率分别为0%、0%、3.3%和0%，巴氏杀菌乳样品的检出率分别为0%、0%、8.0%和2.0%；所有牛奶样品中氟喹诺酮和四环素测定浓度均低于方法检测限，链霉素和林可霉素的最大浓度分别为21.16和16.48 μg/L，均未超过欧盟、食品法典委员会和我国标准中规定的最大残留限量值(MRLs)。由此推断，当前我国市场上UHT和巴氏杀菌乳中氟喹诺酮、四环素、链霉素和林可霉素等兽药的残留情况并没有超标，是安全的。 |

| Abstract: |
| In order to assess the veterinary drug residues in liquid milk products on the market in China, a total of 150 ultra-heat temperature(UHT)and 50 pasteurized milk samples were collected on 2016 and 2017. ELISA-based visual microarray technology was used to detect veterinary drugs including quinolones, tetracyclines, streptomycin and lincomycin. The results showed that the detection rates of fluoroquinolone, tetracycline, streptomycin and lincomycin were 0%, 0%, 3. 3% and 0% in UHT milk samples, respectively, and their detection rates in pasteurized milk samples were 0%, 0%, 8. 0% and 2. 0%, respectively. The concentrations of fluoroquinolone and tetracycline in all milk samples were lower than the detection limit of the method. The maximum concentrations of streptomycin and lincomycin were 21. 16 and 16. 48 μg/L, respectively, both of which were below the maximum residue limits of European Union, the Codex Alimentarius Commission and China standards. It is concluded that the residual conditions of fluoroquinolone, tetracycline, streptomycin and lincomycin in UHT and pasteurized milk in China are under control and safe. |
