Intestinal Parasitic Infection and Its Associated Factors among Food Handlers in Ginnir Town, Bale Zone, Southeast, Ethiopia
Abstract Background: Intestinal parasitic infections are the most common infections in the developing world. Globally, out of the 1.5 billion annual cases of diarrhea, about 70% or 1.05 billion cases are thought to be caused by biological contamination of food. In Ethiopia, due to poor environmental sanitation, low awareness about personal hygiene, lack of pure potable water, and improper faecal disposal, intestinal parasitic infections are highly prevalent. Thus, the aim of this study was to determine the prevalence and associated factors of intestinal parasitosis among food handlers working in food and drinking establishments in Ginnir town, southeast, Ethiopia.Method: Cross-sectional study design was employed from May 1 to May 29, 2014 in food and drinking establishments in Ginnir town. A total of 348 food handlers were selected using simple random sampling method. Stool specimens were collected and examined using direct saline and formol-ether concentration methods. Bivariate and multivariable logistic regression analysis was performed. A P-value <0.05 was considered as an indicator of statistical significance.Result: The overall prevalence of intestinal parasitosis among food handlers was 48/348(13.8%). Entamoeba histolytica/dispar 23/348(6.6%) followed by Giardia lamblia 16/348(4.6%), Ascaris lumbricoides 7/348(2.0%) and Strongyloides stercolaris 2/348(0.6%) were the most prevalent parasites. Moreover, comparable proportions of parasites were detected in males (52%) and females (48%). Habit of eating raw/under cooked vegetables (AOR=2.6, 95% CI=2.94-8.67) and poor personal hygiene (AOR=3.39, 95% CI=1.51-10.23) were factors significantly associated with intestinal parasitic infections.Conclusion: The prevalence of intestinal parasitosis among food handlers is relatively low. Though the prevalence rate is low; regular medical check-up, training and health education on safe food handling and processing should be given for all food handlers.
