Abstract

BACKGROUND

Food borne disease are major health problems in developing countries like Ethiopia. Food handlers with poor personal hygiene working in food establishments could be potential sources of disease due to pathogenic organisms. However; information on disease prevalence among food handlers working in University of Gondar cafeterias are very scarce. The aim of this study is to assess the prevalence of nasal carriage of Staphylococcus aureus, their drug resistance pattern and prevalence of intestinal parasites among food handlers working in University of Gondar student's cafeterias.

METHOD

A cross sectional study was conducted among food handlers working in University of Gondar student's cafeterias. A pretested structured questionnaire was used for collecting data. Nasal swab and stool were investigated for S. aureus and intestinal parasites; respectively as per the standard of the laboratory methods.

RESULTS

Among 200 food handlers, females comprised 171(85.5%). The majority (67.5%) of the food-handlers were young adults aged 18-39 years. One hundred ninety four (97%) of the food handlers were not certified as a food handler. Forty one (20.5%) food handlers were positive for nasal carriage of S. aureus, of these 4(9.8%) was resistant for methicilin. Giardia lamblia was the most prevalent parasites 22 (11%), followed by Ascaris lumbricoides 13(6.5%), Entamoeba histolytica 12 (6%), Strongyloides stercolaris (0.5), Taenia species 1(0.5%) and Schistosoma mansoni 1(0.5%).

CONCLUSION

The finding stressed that food handlers with different pathogenic micro organisms may pose significant risk on the consumers. Higher officials should implement food handler's training on food safety, periodic medical checkup and continuous monitoring of personal hygiene of food handlers.

摘要

背景

食源性疾病是埃塞俄比亚等发展中国家的主要健康问题。在食品场所工作的个人卫生条件差的食品从业人员可能由于病原体而成为疾病的潜在来源。然而,关于在贡德尔大学自助餐厅工作的食品从业人员中疾病流行的信息非常有限。本研究旨在评估在贡德尔大学学生自助餐厅工作的食品从业人员中金黄色葡萄球菌的鼻腔携带率、耐药模式以及肠道寄生虫的流行情况。

方法

对贡德尔大学学生自助餐厅的食品从业人员进行横断面研究。使用经过预测试的结构化问卷收集数据。按照实验室方法的标准,分别对鼻拭子和粪便进行金黄色葡萄球菌和肠道寄生虫检测。

结果

在 200 名食品从业人员中,女性占 171 人(85.5%)。大多数(67.5%)食品从业人员为 18-39 岁的年轻成年人。194 名(97%)食品从业人员未获得食品从业人员认证。41 名(20.5%)食品从业人员鼻腔携带金黄色葡萄球菌呈阳性,其中 4 名(9.8%)对甲氧西林耐药。贾第鞭毛虫是最常见的寄生虫,22 例(11%),其次是蛔虫 13 例(6.5%)、溶组织内阿米巴 12 例(6%)、粪类圆线虫(0.5%)、带绦虫 1 例(0.5%)和曼氏血吸虫 1 例(0.5%)。

结论

研究结果强调,携带不同病原微生物的食品从业人员可能对消费者构成重大风险。高级官员应实施食品从业人员食品安全培训、定期体检和持续监测食品从业人员个人卫生。
