Prevalence of Toxocara spp. Eggs in the Soil of Marand Parks: A Local Report

Background: Toxocariasis caused by Toxocara canis and Toxocara cati is a worldwide zoonotic parasitic infection that can be acquired from contaminated soil. The soil contamination of public places and parks is one of the effective factors in human pollution. Objectives: The current study was designed and implemented to investigate the prevalence of Toxocara species eggs in the soil of Marand parks (in the northwest of Iran). Materials and Methods: Present cross-sectional study was conducted between September and December 2021. Overall, 160 samples were collected from 10 large parks with high traffic and then analyzed by parasitological techniques (sucrose flotation). Results: The overall prevalence was assessed at 27.2% in Marand public parks; the highest and lowest prevalence rates were related to Besat park and Shahr park, respectively (39.6% vs. 19.3%). The maximum number of recovered eggs from 100 grams of soil was seven eggs. Conclusion: Considering the remarkable prevalence of Toxocara spp. in the Marand parks, control and preventive measures seem necessary.
