What specific parasitic eggs found in soil are mentioned in relation to transfer via an earthworm's surface?

Eggs from *Toxocara*, the roundworm species often found in dogs and cats

The text specifically cites *Toxocara* as an example of a parasitic concern related to soil exposure. *Toxocara* eggs originate from the feces of infected dogs or cats deposited in the soil environment. When an individual handles an earthworm crawling in this contaminated soil, these microscopic eggs can adhere to the worm's surface or the handler's hands. The resulting risk pathway involves accidentally touching the mouth or eyes with contaminated hands, leading to the ingestion of these eggs. Once swallowed, the larvae hatch and begin migration within the human body, establishing the *Toxocara* infection, illustrating how touching the worm is merely a secondary step in a larger ingestion route.
