Although antibiotics are valuable drugs for treatment of certain infections, their presence in foodstuff derived from animals is a potential public health hazard. They pose a serious threat as they are implicated in direct toxicity; allergic reactions; disturbance of the normal gut microbiota, carcinogenesis, and emergence of antibioticresistant bacteria. This study investigated the occurrence of antibiotic residues in raw milk samples derived from cows and buffaloes. Samples were collected randomly from different retail outlets in Erbil city (Iraq) from January 1 to June 30, 2019. The residues were detected by two diffusion assays against bacteria on agar plates. The total occurrence of residues ranged from 11.9% to 13.4% of screened milk samples. No significant differences were found between milk type or location of animal rearing (urban or suburban). Regarding the seasonal variations, spring was found to be associated with gradual decrease in antibiotic residues levels in milk. Such occurrence rate of residues is alarming and require authorities to observe the quality of raw milk introduced to markets for consumption. Further evaluation of antibiotic stability period in raw milk is also necessary.
尽管抗生素是治疗某些感染的宝贵药物，但它们在动物源性食品中的存在是一种潜在的公共卫生危害。它们构成严重威胁，因为它们与直接毒性、过敏反应、正常肠道微生物群的紊乱、致癌作用以及抗生素耐药菌的出现有关。本研究调查了来自奶牛和水牛的生乳样品中抗生素残留的情况。2019年1月1日至6月30日，从伊拉克埃尔比勒市的不同零售网点随机采集样品。通过在琼脂平板上针对细菌的两种扩散试验检测残留。残留的总发生率在筛查的牛奶样品的11.9%至13.4%之间。在牛奶类型或动物饲养地点（城市或郊区）之间未发现显著差异。关于季节变化，发现春季与牛奶中抗生素残留水平的逐渐下降有关。这种残留发生率令人担忧，需要当局关注投放市场供消费的生乳质量。对生乳中抗生素稳定期进行进一步评估也是必要的。
