Parks and playgrounds are a hotspot for dangerous dog parasite

Dog and cat roundworms have been linked to loss of vision, difficulty breathing, asthma, epilepsy and cognitive decline in people

The roundworms of dogs (Toxocara canis) and cats (Toxocara cati) can cause hard-to-diagnose disease in people

New research from zoologists at Trinity College Dublin has pinpointed park entrances and playgrounds in Dublin as hotspots for roundworm eggs, with subsequent analysis strongly implying they have come from dog poop.

While unsavoury, the findings do pinpoint these locations for targeted interventions to reduce the risk of human infection
