The treatment of animals with antimicrobial products may lead to the contamination of edible tissues by their residues, which may represent a risk to human health. Therefore, this study aimed to determine the level of antimicrobial residues in food-producing animals (chicken, beef, and milk) in Lebanon. A total of 310 samples were collected and analysed using an LC-MS/MS for the determination of 48 compounds belonging to different families in order to map their compliance according to the European Commission decision 2002/657/EC. Results show that 60% of the analysed samples were not contaminated by any residue, while 12% presented a concentration higher than the MRLs for tetracyclines, sulphonamides, quinolones, and macrolides. Results revealed that chicken were the most contaminated by antimicrobial residues, when compared to beef and milk. The obtained results demonstrate the uncontrolled use of antimicrobials in some Lebanese farms and claim for better management of livestock.

通过LC-MS对黎巴嫩食品生产动物中的抗菌素残留进行了调查。

用抗菌产品处理动物可能会导致其残留物污染可食组织,从而可能危害人类健康。因此,本研究旨在确定黎巴嫩食品生产动物(鸡肉,牛肉和牛奶)中的抗菌素残留水平。总共收集了310个样品,并使用LC-MS / MS进行了分析,以测定48个属于不同族的化合物,以便根据欧洲委员会第2002/657 / EC号决定对其合规性进行绘图。结果表明,60%的被分析样品没有被任何残留物污染,而12%的浓度高于四环素,磺酰胺,喹诺酮和大环内酯类药物的最大残留限量。结果显示,与牛肉和牛奶相比,鸡肉受抗生素残留的污染最大。
