In the present study, 199 raw milk samples were analysed for beta-lactams, tetracyclines, sulfonamides and quinolones. They were obtained from collection tanks of milk routes in 10 provinces of China. The occurrence and concentration range of the four antibiotics were investigated by competitive enzyme-linked immunosorbent assay methods. At the detectable level, 0.5%, 47.2% and 20.1% of samples were positive for beta-lactams, quinolones and sulfonamides, respectively. No sample was positive for tetracyclines. Beta-lactams were positive only in Beijing while quinolones and sulfonamides were positive in all provinces. One (0.5%) sample for beta-lactams was above the maximum residue limits (MRLs, regulated by EU, CAC and China). The maximum concentrations for sulfonamides and quinolones were 16.28 µg kg⁻¹ and 23.25 µg kg⁻¹ which were under their maximum residue limits. More precaution should be taken on antibiotic controls because of the high detection rate of some antibiotics.
本研究对来自中国 10 个省份奶罐的 199 份生鲜乳样品进行了β-内酰胺类、四环素类、磺胺类和喹诺酮类药物残留检测。采用竞争酶联免疫吸附分析法检测了这 4 类抗生素的残留情况和浓度范围。在可检测水平下，β-内酰胺类、喹诺酮类和磺胺类药物的阳性检出率分别为 0.5%、47.2%和 20.1%，未检出四环素类药物。β-内酰胺类药物仅在北京检出，而喹诺酮类和磺胺类药物在所有省份均有检出。1 份β-内酰胺类药物样品（0.5%）超过了最大残留限量（欧盟、CAC 和中国规定）。磺胺类和喹诺酮类药物的最高浓度分别为 16.28μg/kg 和 23.25μg/kg，均低于其最大残留限量。鉴于部分抗生素的高检出率，应更加注意抗生素的控制。
