Food-handlers with poor personal hygiene working in food-service establishments could be potential sources of infection due to pathogenic organisms. In May 2011, a cross-sectional study was undertaken to determine the prevalence of bacteria and intestinal parasites among food-handlers working with Cuban health personnel in Haiti. Stool specimens were collected from 56 food-handlers and samples were examined using standard procedures. Of the food handlers, 26.8% had one bacterial or intestinal parasite. The most prevalent species of organism found were Blastocystis spp. (9%), followed by Vibrio cholerae O1 serotype Ogawa, Aeromonas spp. and Giardia intestinalis, each one with 4%. The prevalence of intestinal parasites was 19.7%. Five out of 56 food handlers had diarrhea at the time the study was conducted. It was found that there was a lower prevalence of V. cholerae O1 serotype Ogawa in comparison to intestinal parasites. The study highlights the importance of the precautions that must be taken in cholera-affected countries by medical teams and their organizations, with emphasis on the preparation, processing, and serving of meals. The recommendation is to intensify continuing education programs, periodical laboratory examinations to detect carriers and food-handlers reporting sick, and to observe strict adherence to hygienic food-handling practices. In addition, food handlers with diarrhea should refrain from preparation or delivery of food.
在食品服务机构工作且个人卫生状况不佳的食品从业人员可能会因致病生物而成为潜在的感染源。2011年5月，开展了一项横断面研究，以确定在海地与古巴卫生人员一起工作的食品从业人员中细菌和肠道寄生虫的流行情况。从56名食品从业人员中采集了粪便样本，并使用标准程序进行检测。在这些食品从业人员中，26.8%的人感染了一种细菌或肠道寄生虫。发现最常见的生物体种类是芽囊原虫属（9%），其次是霍乱弧菌O1小川血清型、气单胞菌属和肠道贾第虫，每种均为4%。肠道寄生虫的流行率为19.7%。在进行研究时，56名食品从业人员中有5人腹泻。结果发现，与肠道寄生虫相比，霍乱弧菌O1小川血清型的流行率较低。该研究强调了医疗队及其组织在霍乱流行国家必须采取的预防措施的重要性，重点是膳食的准备、加工和供应。建议加强继续教育项目、定期进行实验室检查以检测携带者和报告患病的食品从业人员，并严格遵守卫生的食品处理规范。此外，腹泻的食品从业人员应避免准备或递送食物。
