Abstract The aim of this study was to evaluate environmental contamination by helminth eggs with zoonotic potential that were found in dog feces in the vicinity of elementary schools. Seventy-nine samples of dog feces were collected from 28 municipal schools located in five neighborhoods in Pelotas, Rio Grande do Sul (RS), Brazil. The samples were processed using the Willis-Mollay technique and analyzed using an optical microscope (40X), to identify any parasite eggs present. All neighborhoods were positive and 74.7% of the samples exhibited one or more helminth genera. The agent with the highest prevalence was Ancylostoma spp. (93.2%), followed by Trichuris spp. (18.6%), Toxocara spp. (11.9%) and Toxascaris (1.7%). These data show that there is a need for greater care towards controlling these helminths with zoonotic potential, including responsible pet ownership and daily activities to clean and collect dog feces in the vicinity of schools, because these are places where children play and study.
