Salmonellosis and Shigellosis remain a major public health problem across the globe, particularly in developing countries like Ethiopia, where hand hygiene and food microbiology are still below the required standards. The growing problem of antimicrobial resistance species also continues to pose public health challenges. This study assessed the prevalence and antimicrobial susceptibility pattern of Salmonella and Shigella species among asymptomatic food handlers. A cross-sectional study was conducted among 417 randomly selected asymptomatic food handlers. Data were collected using a structured questionnaire. The stool specimens collected were examined for Salmonella and Shigella species using standard bacteriological methods. Descriptive statistics were used to describe the basic features of the data.
The overall prevalence of Salmonella and Shigella species was 5.04%. Salmonella and Shigella species were 76.2% resistant to both co-trimoxazole and tetracycline, 71.4% to amoxicillin and 66.7% to chloramphenicol. Moreover, 85.7% of Salmonella and Shigella species were multidrug resistant. The findings highlighted the food handlers as potential sources of food borne infections, which demands the establishment of appropriate hygiene and sanitary control measures at the University cafeterias.
沙门氏菌病和志贺氏菌病仍然是全球主要的公共卫生问题，尤其是在像埃塞俄比亚这样的发展中国家，那里的手部卫生和食品微生物学水平仍低于要求标准。抗菌耐药菌问题日益严重，也继续对公共卫生构成挑战。本研究评估了无症状食品从业人员中沙门氏菌和志贺氏菌的流行情况及抗菌药敏模式。对417名随机选择的无症状食品从业人员进行了横断面研究。使用结构化问卷收集数据。采用标准细菌学方法对采集的粪便标本进行沙门氏菌和志贺氏菌检测。使用描述性统计来描述数据的基本特征。
沙门氏菌和志贺氏菌的总体流行率为5.04%。沙门氏菌和志贺氏菌对复方新诺明和四环素的耐药率均为76.2%，对阿莫西林的耐药率为71.4%，对氯霉素的耐药率为66.7%。此外，85.7%的沙门氏菌和志贺氏菌具有多重耐药性。研究结果突出了食品从业人员作为食源性感染潜在来源的问题，这要求在大学食堂建立适当的卫生和清洁控制措施。
