This study aimed to investigate the presence of infectious intestinal parasites in individuals undergoing enterectomy and enrolled in the Ostomy Program of the Department of Health Management, Health System (SUS), in the municipality of Pelotas, Brazil. An epidemiological questionnaire was applied to 71 individuals who participated in the survey, to assess demographic, social, and cultural effects on basic knowledge concerning enteroparasites. They also underwent fecal examinations by the Faust, Ritchie and Baermann-Moraes methods. The prevalence of monoparasitism carriers was 5.6%: Enterobius vermicularis larvae and eggs, Taenia sp. eggs and Strongyloides stercoralis larvae were diagnosed. As for knowledge about parasites, 69% of interviewees had general knowledge of the subject and 56.3% knew of the importance of hygiene for hands and food. However, 33.8% of respondents did not know of the necessary precautions for preventing intestinal parasites, and 50.7% of the respondents did not understand the real importance of the subject. There were no signs or symptoms that would indicate the presence of parasites in the patients.
