摘要

食源性病原体构成重大食品安全风险,了解它们的存在和耐药性模式对公共卫生干预至关重要。本研究评估了来自加纳库马西大都会库马西屠宰场和Kejetia市场的生牛肉样本中选定食源性病原体的流行情况和抗生素耐药性。对牛肉样品进行蜡样芽孢杆菌、单核增生李斯特菌和大肠杆菌的检测。进行抗生素药敏试验以确定耐药谱。研究结果显示,病原菌的检出率各不相同,蜡样芽孢杆菌检出率为27.55%,单核增生乳杆菌检出率为55.41%,大肠杆菌检出率为59.91%。大约76%的样品至少含有三种细菌中的一种,微生物负荷高于细菌特异性可接受标准。大部分大肠杆菌ESBL阳性,蜡样芽孢杆菌和单核增生乳杆菌均为多药耐药,多重耐药指数均大于0.2。单核增生乳杆菌和蜡样芽孢杆菌菌株分别出现9种和4种AMR模式。需要定期监测食源性病原体的流行情况和抗菌素耐药性概况,以防止潜在的食源性疫情,影响监管和政策变化,规划抗菌素耐药性管理规划,并保持消费者对出售肉类的信心。

Prevalence and Antibiotic Resistance of Selected Foodborne Pathogens in Beef Sold Within Kumasi Metropolis, Ghana

Prevalence and Antibiotic Resistance of Selected Foodborne Pathogens in Beef Sold Within Kumasi Metropolis, Ghana

Foodborne pathogens pose significant food safety risks and understanding their presence and resistance patterns is crucial for public health interventions. This study assessed the prevalence and antibiotic resistance profiles of selected foodborne pathogens in raw beef samples from Kumasi Abattoir and Kejetia Market in the Kumasi Metropolis in Ghana. Beef samples were analyzed for Bacillus cereus, Listeria monocytogenes, and Escherichia coli. Antibiotic susceptibility testing was conducted to determine resistance profiles. The study revealed the varying prevalence of the pathogens, with B. cereus detected in 27.55% of the samples, L. monocytogenes in 55.41%, and Escherichia coli in 59.91%, respectively. Approximately 76% of all samples had at least one of the three bacteria, with microbial loads above bacteria-specific acceptable standards. Most of the E. coli strains were positive for ESBL, while all B. cereus and L. monocytogenes strains were multidrug resistant with multiple antibiotic-resistant indices of more than 0.2. Nine and four AMR patterns emerged in the L. monocytogenes and B. cereus strains, respectively. Regular surveillance is needed to monitor the prevalence and AMR profiles of foodborne pathogens to prevent potential foodborne outbreaks, influence regulatory and policy changes, plan AMR stewardship programmes, and maintain the confidence of consumers in meats for sale.
