BACKGROUND
As in most of African countries, intestinal parasites have been widely distributed in Ethiopia and are among the 10 top causes of morbidity and mortality nationwide. Statistics for food-borne illness in various industrialized countries show that up to 60% of cases may be caused by poor food handling techniques and by contaminated food served in food service establishments. Epidemiological information on the prevalence of various intestinal parasitic infections in different regions/localities is a prerequisite to develop appropriate strategies.
OBJECTIVE
This study aimed to determine the magnitude of intestinal parasites among food handlers working in different food service establishments in Gondar city.
METHODS
A cross-sectional study was conducted with food handlers working in different food service establishments in Gondar city. Stool samples were collected from 350 food handlers and processed using the formol-ether concentration method and then microscopically examined for intestinal parasitic infections. Pre-tested and structured questionnaire was used to study the socio-demographic characteristics of food handlers. Chi-square test and -value were used to assess the associations between risk factors and the parasite isolation rate. The -value ≤0.05 was considered as statistically significant.
RESULTS
Of the 350 food handlers, 160 (45.71%) had parasites. Among the isolated parasites, was found to be the most prevalent parasite 35.63%, followed by hookworm 19.38%, 16.25%, 10.00%, 8.13%, 6.88%, and , and species each accounting 1.25%.
CONCLUSION
The result of the study indicated that the magnitude of intestinal parasitosis among food handlers working at different levels of food establishments in Gondar, Ethiopia, was found to be high. Being at lower educational level and inactive role of the town's municipality are determined as a risk factor for parasitic positivity of food handlers.
背景
与大多数非洲国家一样，肠道寄生虫在埃塞俄比亚广泛分布，是全国发病率和死亡率的十大主要病因之一。各工业化国家食源性疾病的统计数据表明，高达60%的病例可能是由不良的食品处理技术以及食品服务机构提供的受污染食品所致。了解不同地区/地点各种肠道寄生虫感染的流行情况的流行病学信息是制定适当策略的先决条件。
目的
本研究旨在确定贡德尔市不同食品服务机构工作的食品从业人员中肠道寄生虫的感染程度。
方法
对贡德尔市不同食品服务机构工作的食品从业人员进行了一项横断面研究。从350名食品从业人员中采集粪便样本，采用甲醛乙醚浓缩法进行处理，然后进行显微镜检查以检测肠道寄生虫感染情况。使用经过预测试的结构化问卷来研究食品从业人员的社会人口学特征。采用卡方检验和P值来评估危险因素与寄生虫分离率之间的关联。P值≤0.05被认为具有统计学意义。
结果
在350名食品从业人员中，160人（45.71%）感染了寄生虫。在分离出的寄生虫中，蛔虫是最常见的寄生虫，占35.63%，其次是钩虫，占19.38%，鞭虫占16.25%，绦虫占10.00%，姜片虫占8.13%，溶组织内阿米巴占6.88%，贾第虫和隐孢子虫各占1.25%。
结论
研究结果表明，在埃塞俄比亚贡德尔不同层级食品机构工作的食品从业人员中，肠道寄生虫感染程度较高。文化程度较低以及该市市政当局的不作为被确定为食品从业人员寄生虫阳性的危险因素。
