Food-borne infections are common public health problems worldwide. A street food handler with poor personal hygiene contributes to the transmission of intestinal parasites and enteric bacteria to the public via contaminated foods. In Ethiopia, health risks associated with street food are common. Previous studies in this area are scanty. Hence, the aim of this study was to determine the prevalence of intestinal parasites, enteric bacterial infections, and antimicrobial susceptibility among street food handlers in Jimma town.
A cross-sectional study was conducted from October to December 2020 among 260 street food handlers in Jimma town. A semi-structured questionnaire was used to collect data through face-to-face interviews. About 3 grams of the fecal specimen were collected from each food handler for bacterial culture and concentration techniques. The data were entered into Epi-Data 3.1 and analyzed by SPSS version 20. Associated factors were identified by using binary logistic regression analysis. A statistically significant association was determined at a -value less than 0.05.
The overall prevalence of intestinal parasites and enteric bacterial pathogens was 39.2% (33.3%-45.2%) and 8.85% (5.4%-12.3%), respectively. (18.5%) and (8.1%) were the most predominant parasite and enteric bacterial isolates, respectively. Not trimming fingernails (AOR = 2.884; 95% CI: 1.682-4.945) and not washing hands with soap after toilet (AOR = 3.342; 95% CI: 1.939-5.761) were factors associated with increased risk of infection by intestinal parasites or enteric bacterial pathogens. All and isolates were 100% resistant to ampicillin.
The infection with intestinal parasites and enteric bacterial pathogens detected in this study indicated that street food handlers may serve as sources of pathogens/parasites for transmission and experience morbidities due to the infections. Therefore, periodic medical checkups and creating awareness of personal hygiene are mandatory to reduce the risk of infections.
食源性感染是全球常见的公共卫生问题。个人卫生状况差的街头食品从业者会通过受污染的食物将肠道寄生虫和肠道细菌传播给公众。在埃塞俄比亚，与街头食品相关的健康风险很常见。此前该领域的研究较少。因此，本研究的目的是确定吉姆马镇街头食品从业者中肠道寄生虫、肠道细菌感染及抗菌药物敏感性的流行情况。
2020年10月至12月在吉姆马镇对260名街头食品从业者进行了一项横断面研究。通过面对面访谈使用半结构化问卷收集数据。从每位食品从业者收集约3克粪便标本用于细菌培养和浓缩技术。数据录入Epi-Data 3.1并使用SPSS 20版进行分析。通过二元逻辑回归分析确定相关因素。在P值小于0.05时确定具有统计学意义的关联。
肠道寄生虫和肠道细菌病原体的总体流行率分别为39.2%（33.3%-45.2%）和8.85%（5.4%-12.3%）。 （18.5%）和 （8.1%）分别是最主要的寄生虫和肠道细菌分离株。不修剪指甲（比值比[AOR]=2.884；95%置信区间[CI]：1.682-4.945）和便后不用肥皂洗手（AOR=3.342；95%CI：-5.761）是与肠道寄生虫或肠道细菌病原体感染风险增加相关的因素。所有 和 分离株对氨苄西林的耐药率均为100%。
本研究中检测到的肠道寄生虫和肠道细菌病原体感染表明，街头食品从业者可能是病原体/寄生虫传播的来源，并因感染而患病。因此，定期进行医学检查和提高个人卫生意识对于降低感染风险至关重要。
