%X 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 solution of sodium dichromate with density of 1.35, 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 hookworms 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. A frequ¨ºncia de contamina  o parasit¨¢ria de ¨¢reas p¨²blicas de Pelotas, Rio Grande do Sul, Brasil, foi avaliada entre junho de 2010 e maio de 2011, com coletas mensais de amostras de solo de oito pra as. Das 400 amostras submetidas ¨¤ t¨¦cnica de centr¨ªfugo-flutua  o em solu  o de dicromato de s¨®dio com densidade de 1,35, 176 (44%) apresentaram pelo menos uma forma parasit¨¢ria e, das amostras positivas, 29 (16,5%) estavam poliparasitadas. Os resultados demonstraram relevante ¨ªndice de contamina  o do solo em todas as pra as avaliadas, com maiores ¨ªndices de positividade para ovos de ancilostom¨ªdeos (13,5%) e ovos de Toxocara (8,8%), sendo tamb¨¦m identificados ovos de Trichuris, Ascaris e Capillaria. O estudo demonstrou a contamina  o ambiental de pra as p¨²blicas e os riscos a que a popula  o est¨¢ exposta em rela  o a doen as causadas por geoparasitos zoon¨®ticos e sugere que medidas de saneamento e educa  o em sa¨²de devem ser implementadas no munic¨ªpio.
