Town Bank - Toxocariasis is a parasitic infection caused by dog roundworms and is considered by some researchers to be the "most common human parasitic worm infection in the United States." Toxocara eggs are found in the sand where dogs go to the bathroom. So, next time your child or you sit or walk barefoot in the sand along the bay, ask yourself if this is where an infected dog went to the bathroom. It's not only reckless, it's absolutely stupid!
