Background: Intestinal parasite infections are major global public health problems. The majority of persons infected reside in Sub-Saharan Africa with a high burden of the disease. Very few studies have been done in Ethiopia and none exist at Wachemo University, Southern Ethiopia. The present study aimed to investigate intestinal parasitic infections and associated factors among Wachemo University students’ cafeteria food handlers. Methods: Institution-based cross-sectional study was conducted on 212 randomly selected food handlers from 15, February to 05, March/2019. A structured questionnaire was used to collect data and standard laboratory procedures were employed to collect stool and finger specimens and analyzed them for intestinal parasites. Data were edited, cleaned, entered, using EPI data 3.3.1, and analyzed by statistical package for social science version 20. A stepwise logistic regression model was used to calculate the odds ratios and 95% confidence interval for the different factors. Results: Of 212, the majority 63.7% were females and 48.1% attended grades 9 to 10. Of the stool and fingernail specimens examined, 29.7 % and 5.6% were positive for different parasites, respectively. The most prevalent parasite is Ascaris lumbricoides (12.7%) followed by Hookworm (6.6%), Giardia lamblia (4.7%), Taenia saginata (2.4%), and mixed infection (3.3%). Although several factors showed significant association with intestinal parasitosis, attending secondary level education 94.5% (AOR: 0.055; 95% CI [0.007-0.413]), fingernail status (AOR: 0.330; 95% CI [0.113-0.965]), and hand washing with soap and water after toilet use (AOR: 0.332; 95% CI [0.125-0.884]) were the significant variables in multivariable analysis ( P < .05). Conclusions: The results demonstrated intestinal parasite infections as a public health issue in Ethiopia that requires attention. Appropriate intervention programs like encouraging food handlers to practice good hygiene, routine hand washing at key times, and nail trimming should be implemented.
