Abstract
The frequency of parasitic contamination of public areas in the municipality of Pelotas, state of Rio Grande do Sul, Brazil, was studied between June 2010 and May 2011, when soil samples were collected from eight city squares. Out of 400 samples submitted to centrifugal floatation technique in a solution of sodium dichromate, 176 (44%) proved positive for at least one parasite; 29 (16.5%) samples were multi-infested. The results showed that there was a significant soil contamination rate in all the parks included in the study. The positivity rate was higher for ancylostomideos eggs (13.5%) and Toxocara eggs (8.8%); Trichuris, Ascaris and Capillaria eggs were also detected. This study shows the risks to which the population is exposed in relation to zoonotic geohelminths, and suggests that sanitation and health education measures should be implemented in the municipality. Keywords: Helminths, environmental contamination, Toxocara.
