Nowadays veterinarians and poultry producers use antibiotics to increase growth rates, bird health, and feed efficiency, egg production, for preventative and therapeutic purposes, and to lessen the prevalence of poultry diseases. Most poultry producers have used a variety of antibiotics, either with or without veterinarian instruction. Although antibiotics are beneficial for the majority of their uses, their unauthorized use has resulted in residues accumulated in poultry products intended for human consumption which represents a serious risk to the general public that could be toxicological, microbiological, or immunological.
This study aimed to the estimation of the residues of three major antimicrobials used in the intensive chicken-rearing systems in Egypt, namely Oxytetracycline (OTC), Gentamicin, and Ciprofloxacin. Moreover, the effect of cooking on such residues was investigated.
A total of 100 chicken meat samples (breast, thigh, gizzard, liver, 25 each) were examined for detection of the aforementioned antimicrobials using the microbial inhibition assay and high-performance liquid chromatography (HPLC). Besides, samples containing the highest antimicrobial residues were examined for the effect of boiling for 30 minutes on such residues.
The obtained results revealed that 23%, 21%, and 17% of the examined samples were positive for OTC, gentamicin, and ciprofloxacin residues , respectively . Cooking (boiling) for 30 minutes showed a reduction of the antibiotic residue by 88.2%, 95.2%, and 31.3%, respectively.
Antimicrobial residues were detected in the chicken meat parts retailed in Egypt. Cooking can reduce the antimicrobial residues at least in part.
如今，兽医和家禽饲养者使用抗生素来提高生长速度、禽类健康和饲料效率、产蛋量，用于预防和治疗目的，并降低禽病的流行率。大多数家禽饲养者都使用了各种抗生素，无论是在没有兽医指导的情况下。尽管抗生素在大多数用途中都是有益的，但它们的未经授权使用导致了在供人类食用的家禽产品中积累了残留物，这对公众构成了严重的风险，可能具有毒理学、微生物学或免疫学的风险。
本研究旨在估计在埃及集约化养鸡系统中使用的三种主要抗菌药物（土霉素（OTC）、庆大霉素和环丙沙星）的残留量。此外，还研究了烹饪对这些残留量的影响。
共检查了 100 个鸡肉样本（鸡胸肉、鸡腿肉、肌胃、肝脏，每个部位 25 个），使用微生物抑制测定法和高效液相色谱法（HPLC）检测上述抗菌药物的残留量。此外，对含有最高抗菌残留量的样本进行了煮沸 30 分钟对这些残留量的影响的检查。
结果显示，23%、21%和 17%的检查样本分别对 OTC、庆大霉素和环丙沙星残留呈阳性。烹饪（煮沸）30 分钟可使抗生素残留分别减少 88.2%、95.2%和 31.3%。
在埃及零售的鸡肉部分中检测到了抗菌药物残留。烹饪至少可以部分减少抗菌药物残留。
