The objective of this work was to evaluate the contamination of public parks in the district of Huánuco, Perú with eggs of Toxocara canis. 32 soil samples were taken in each of 11 parks for a total of 352 samples in May and June of 2014. Parks were selected at random. In each park, 2-3 kg soil was collected according to the double “W” method. Flotation with a saturated sugar solution was used. Samples were considered positive when at least one egg of T. canis was found. Of the 11 parks sampled, T. canis eggs were found in 90.9%. Seven parasites were found along with T. canis in the soil. The sequence of parasite prevalence was in the following descending order: T. canis> Strongylus type eggs of Ancylostoma caninum > A. caninum larvae = Blastocystis hominis > Trichuris vulpis= Entamoeba sp. > Capillaria sp. = Balantidium coli. Parasite richness was 2.45 ± 1.21 (1-4) par...
