OBJECTIVE: To assess the occurrence of zoonotic parasites in dog feces collected in public areas of the city of Ribeirão Preto, to alert to the risk of human infection. METHODS: From May to December, 2003, 78 public squares located in five different areas of the city were visited: southwest, northwest, north, central and southeast. We collected 331 fecal canine pools that were processed by the spontaneous sedimentation technique. RESULTS: 56.8% of pools presented zoonotic parasites such as: Ancylostoma spp. (41.7%), Toxocara canis (24.2%), Trichuris vulpis (15.7%), Giardia spp. (10.2%) and Isospora spp. (3.3%). The prevalence of parasites was higher in squares located in the north area of the city (70%). CONCLUSIONS: The adoption of sanitary preservation programs in these sites is necessary in order to prevent environmental contamination by parasites potentially pathogenic to man.
