Antibiotics, especially fluoroquinolones, have been exhaustively used in animal husbandry. However, very limited information on the occurrence and exposure assessment of fluoroquinolone residues in chicken and pork in China is available to date. Thus, a total of 1754 chicken samples and 1712 pork samples were collected from 25 provinces in China and tested by ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) for residual determination of six common fluoroquinolones. The results revealed that the detection frequencies of fluoroquinolone residues were 3.99% and 1.69% in chicken and pork samples. The overall violation frequencies were 0.68% and 0.41% for chicken and pork. Enrofloxacin and its metabolite ciprofloxacin were found to be the most predominant fluoroquinolones. The occurrence of these antibiotics in different sampling regions and market types was analyzed. The %ADI values of enrofloxacin and ciprofloxacin were far less than 100, indicating the health risk associated with the exposure to these aforementioned fluoroquinolone residues via chicken and pork for Chinese children, adolescents, and adults was acceptable. The results provided useful references for Chinese consumers, and helped to appropriately use these antibiotics in poultry and livestock industry.
抗生素,尤其是氟喹诺酮类药物,已在畜牧业中被大量使用。然而,迄今为止,关于中国鸡肉和猪肉中氟喹诺酮类药物残留的发生情况和暴露评估的信息非常有限。因此,从中国25个省份共采集了1754份鸡肉样本和1712份猪肉样本,并采用超高效液相色谱-串联质谱法(UPLC-MS/MS)对六种常见氟喹诺酮类药物的残留进行测定。结果显示,鸡肉和猪肉样本中氟喹诺酮类药物残留的检出频率分别为3.99%和1.69%。鸡肉和猪肉的总体违规频率分别为0.68%和0.41%。恩诺沙星及其代谢物环丙沙星被发现是最主要的氟喹诺酮类药物。分析了这些抗生素在不同采样地区和市场类型中的出现情况。恩诺沙星和环丙沙星的每日允许摄入量(%ADI)值远低于100,表明中国儿童、青少年和成年人通过鸡肉和猪肉接触上述氟喹诺酮类药物残留所带来的健康风险是可以接受的。研究结果为中国消费者提供了有用的参考,并有助于在家禽和畜牧业中合理使用这些抗生素。
