A survey of canine toxocariasis and toxocaral soil contamination in Essex County, New Jersey.

Abstract
Toxocara canis eggs were found in the feces of 33 of 246 dogs and in two of 629 soil samples from 32 public parks in Essex County, New Jersey. Stool samples collected from these areas were free of T. canis eggs. The findings suggest that contamination of soil in public parks with T. canis eggs is not an important factor in the transmission of visceral larva migrans in this county.
