Objective. Establishing the presence of zoonotic gastrointestinal nematodosin soil samples in recreational areas in Suba (one of the largest localities of Bogotá, Colombia) between July 2005 and June 2006. Methodology. The presence of several gastrointestinal parasites' eggs, larvae and oocysts were determined by initial soil sedimentation and later flotation with Sheather solution; some of them were responsible for important zoonotic diseases affecting the human population. Results. Parasites were identified in 376 samples: Ancylostoma larvae (10,7 %), Ancylostoma eggs (0,6 %), Toxocara eggs (5,8 %), Strongyloides eggs (3,3 %), Dipylidium eggs (0,06 %) and Sarcocystis oocysts (0,06 %). Other parasites identified were Toxascaris eggs (0,9 %), Spirocerca eggs (0,25 %) and Isospora oocysts (0,25 %). Some larvae and eggs present in 522 samples could not be classified and there was no evidence of parasites in 702 samples (45 %). 94,2 %, (n=49) of the recreational area was thus polluted. Conclusions. The high percentage of recreational areas so polluted indicated that these places would constitute a risk factor for the transmission of parasitic diseases to animals and human beings. Due to this sanitary problem's relevance in public health programmes, government policy must be determined involving communities so that people are educated to improve their sanitary practices in recreational places regarding caring for their pets. ; Objetivo. Establecer la presencia en los suelos de parques públicos de la localidad de Suba en la ciudad de Bogotá, de nemátodos gastrointestinales zoonóticos durante el periodo comprendido entre Julio de 2005 y Junio de 2006. Metodología. A través de una sedimentación inicial en suelo y posterior flotación con solución de Sheather, fue posible determinar la presencia de huevos, larvas y ooquistes de varios parásitos gastrointestinales, algunos de ellos responsables de importantes enfermedades zoonóticas. Resultados. Se identificados parásitos en 376 muestras que fueron descritos como huevos de Ancylostoma spp 10,7 %, larvas de Ancylostoma spp 0,6 %, huevos de Toxocara spp 5,4 %, huevos de Strongyloides spp 3,3 %, huevos de Dipylidium spp 0,1 % y ooquistes de Sarcocystis spp 0,1 %. Otros parásitos identificados fueron huevos de Toxascaris spp 0,9 %, huevos de Spirocerca spp 0,3 %, ooquistes de Isospora spp 0,3 %. No fue posible clasificar algunas larvas y huevos en 522 muestras; no hubo evidencia de parásitos en 702 muestras 45 %. El 94,2 % (n=49) de los parques estaban contaminados. Conclusiones. Lo anterior, indica que dichos parques constituyen un factor de riesgo para la adquisición de enfermedades parasitarias en los animales y los seres humanos. Debido a la relevancia de este problema de Salud Pública, es necesario instaurar políticas gubernamentales, involucrando la comunidad, educando las familias para mejorar sus prácticas sanitarias en lugares recreacionales con relación a la tenencia adecuada de los animales domésticos (mascotas).
