Background: The Kingdom of Saudi Arabia has a high number of foreign workers, especially those coming from endemic areas with intestinal parasites. Objective: The aim of this study was to determine the prevalence of parasitic infection among foreign workers in Madina, Kingdom of Saudi Arabia. Materials and Methods: There was direct microscopic examination of stool samples by wet smears for parasitic stages. This was followed by the formalin-ethyl acetate concentration technique to confirm and detect parasites not recovered by the wet mount. Results: The total number of foreign workers was 120, 47.5% of whom were males and 52.5% females. They were within the age group of 20-60 years. A total of 53 cases (44.2 %) were infected with IPs. Some samples had double or triple infections, with a total of 69 parasitic infections detected (57.5%). These included Entamoeba histolytica (27.5%), Giardia lamblia (18.8%), hookworm (14.5%), Ascaris lumbricoides (11.6%), Entamoeba coli (7.2%), Trichuris trichiura (5.8%), Strongyloides stercoralis (5.8%) and Hymenolepis nana (4.3%). Furthermore, 1.4% each of Enterobius vermicularis, Schistosoma mansoni and Taenia eggs were found. Conclusion: Foreign workers newly arrived from Asia and Africa carry high rates of IPs infection. It is necessary to increase awareness about occupational health, and the risks of parasite transmission to the local population. Moreover, strict adherence to infection prevention policies is recommended.
