目的:了解苏州地区水产品中喹诺酮类抗生素残留水平,探讨其污染来源,评价其膳食安全性。方法:2011年6月-2012年4月随机采集苏州地区各类水产品,采用超高效液相色谱/质谱进行喹诺酮类抗生素检测。结果:95件水产品中,29件样品检出喹诺酮抗生素残留,检出率30.5%,检出的种类主要为恩诺沙星,与其他几种相比,有显著性统计学差异(P<0.01)。水产品中检出的恩诺沙星残留最高90.6μg/kg,均小于最高残留限量100μg/kg,未超过每日安全摄入量120μg/d。结论:苏州市市售水产品部分存在抗生素残留,需要加强水产品养殖、销售的管理。
Objective: To understand the quinolone residues in aquatic products in Suzhou area, explore the sources of pollution and evaluate their dietary safety. Methods: From June 2011 to April 2012, all kinds of aquatic products in Suzhou were randomly collected, and the quinolone antibiotics were detected by ultra performance liquid chromatography / mass spectrometry. Results: Among the 95 aquatic products, 29 samples were found to be quinolone antibiotic residues with the detection rate of 30.5%. The detected species were mainly enrofloxacin, with significant statistical difference (P < 0.01). Residues of enrofloxacin detected in aquatic products were up to 90.6 μg / kg, both less than the maximum residue limit of 100 μg / kg and not exceeding the daily safety intake of 120 μg / d. Conclusion: Some residues of antibiotics exist in the aquatic products in Suzhou City, and the management of breeding and sales of aquatic products needs to be strengthened.
