To assess the safety of retailed poultry using the prevalence of antibiotic resistance in (), a dominant intestinal microflora.
Two medium-scale farms and 8 well-known retail outlets within the La-Nkwantanang Madina municipality in Accra were purposively selected for sampling from January to March 2020. We randomly sampled raw chicken (n = 25) and poultry fecal matter (n = 50). All samples were immediately transported on ice to the laboratory for analysis within 12 hours after collection. Conventional culture techniques, biochemical tests, and matrix-assisted laser desorption/ionization-time-of-flight mass spectrometry (MALDI-TOF-MS) were used for isolation and identification. The antimicrobial susceptibility of isolated strains (n = 36) was tested using the Kirby Bauer disk diffusion method.
Antimicrobial resistance in ranged from 10.7 % (cefotaxime) to 82.1% (tetracycline) in fecal matter and 0% (gentamicin & cefotaxime) to 62.5% (tetracycline) in chicken. The prevalence of antimicrobial resistant in fecal samples was higher than in chicken for almost all antibiotics tested, except for cefoxitin, cefuroxime, and ceftazidime. Multidrug resistance was 57.1% in from fecal samples compared to 62.5% in chicken.
The high level of resistance to in fecal matter is of public health concern because cross-contamination often occurs during slaughter and processing. This calls for close surveillance and strict adherence to Hazard Analysis and Critical Control Point (HACCP) principles in the chicken production chain to prevent the transmission of antimicrobial-resistant strains through the food chain.
通过评估优势肠道微生物群()中抗生素耐药性的流行情况,来评估零售家禽的安全性。
2020年1月至3月,在阿克拉的拉恩夸坦南·马迪纳市有目的地选择了两个中型农场和8个知名零售点进行采样。我们随机抽取了生鸡肉(n = 25)和家禽粪便(n = 50)。所有样本在采集后12小时内立即用冰运至实验室进行分析。采用传统培养技术、生化试验和基质辅助激光解吸/电离飞行时间质谱(MALDI-TOF-MS)进行分离和鉴定。使用 Kirby Bauer 纸片扩散法检测分离出的(n = 36)菌株的抗菌药敏性。
粪便中对的抗生素耐药性范围为10.7%(头孢噻肟)至82.1%(四环素),鸡肉中为0%(庆大霉素和头孢噻肟)至62.5%(四环素)。除头孢西丁、头孢呋辛和头孢他啶外,几乎所有测试抗生素的粪便样本中耐药的流行率均高于鸡肉。粪便样本中的多重耐药率为57.1%,鸡肉中为62.5%。
粪便中对的高耐药水平引起了公共卫生关注,因为在屠宰和加工过程中经常发生交叉污染。这就要求在鸡肉生产链中密切监测并严格遵守危害分析与关键控制点(HACCP)原则,以防止耐药菌株通过食物链传播。
