Background:Toxocariasis is a common parasitic infection in the world that is caused by larvae stage of two members of family Ascarididae, Toxocara canis and Toxocara cati. The main source of soil contamination with Toxocara eggs is dogs and cats faces. The soil, where Toxocara eggs become infective, is the natural source of infection.
Objectives: This study carried out in order to determine the rate of soil contamination with Toxocara spp. eggs in primary schools and public parks in Kermanshah city, Western Iran.
 Methods: This survey was conducted from September 2014 to January 2015 in Kermanshah city, West of Iran. A total of 192 soil samples were collected from different parks and primary school, 24 parks and 24 primary schools, of six regions. Soil samples were investigated for the presences of Toxocara eggs by flotation technique using sucrose solution and examined under light microscope using 10X and 40X objective.
Results: Out of 192 soil samples, 56 (29.2%) were found to contain Toxocara spp. eggs. Toxocara eggs observed in 21(87.5%) out of 24 studied parks and 11(45.8%) out of 24 studied primary schools. Forty three (44.8%) out of 96 samples from public parks and 13(13.5%) out of 96 samples from primary schools were found to contain Toxocara eggs. Data analysis through chi-square test revealed that there is a significant relationship about the contamination rate between parks and primary schools (χ2 = 22.68, d.f. = 1 and P<0.0001).
Conclusions: The results of this study illustrate that Toxocara spp. are common parasites in soil in the public parks and primary schools in Kermanshah. Thus, soil contamination with Toxocara eggs can be regarded as a potential health problem in this city.
