Park entrances in Dublin parks may be hotspots for infective dog roundworm eggs, according to a recent study conducted by Jason Keegan and colleagues from Trinity College. The researchers collected soil samples from twelve parks in Dublin, focusing on park entrances, playgrounds, sports fields, and popular sitting areas on grass.
The analysis revealed that park entrances were the most heavily contaminated with roundworm eggs, with playgrounds being the second-most contaminated areas. Most of the detected eggs were potentially infective, and the majority belonged to the species Toxocara canis, the common dog roundworm.
Toxocara infections can occur in humans through accidental ingestion of the eggs released by infected animals. While many infected individuals may not show symptoms, some may experience mild to severe symptoms, including eye infections. Infection with Toxocara is a widespread parasitic infection globally.
Based on these findings, the researchers recommend increased preventive measures to reduce contamination at park entrances and playgrounds. They suggest encouraging dog owners to properly dispose of dog feces in these areas and implementing regular monitoring of Toxocara eggs to assess the effectiveness of these efforts. The researchers also propose the use of an accessible and affordable analytical method for standardized monitoring across different sites and over time.
The study highlights the importance of addressing the issue of roundworm contamination in public parks to minimize the risk of zoonotic infections. By providing signage, waste bins, and facilities for cleaning up after dogs, contamination levels can be reduced. The researchers emphasize the need for continued research and intervention to protect public health and improve the cleanliness of park environments.

This research underscores the importance of addressing the issue of roundworm contamination in public parks to protect both animal and human health.
