Toxocara species eggs and Esherichia coli were found, respectively, 43 (30%) and 120 (83%) of 144 sand samples collected from public parks in Hyogo Prefecture, Japan. Epidemiological factors involved in increasing contamination rates of Toxocara spp eggs were found to be (1) small sandpits, (2) sandpits in the small parks, and (3) the sandpits in urban areas crowded with houses. High contamination with Toxocara spp eggs was considered to be due to the high density of animal feces. Control sand (before use for sandpit) was negative for Toxocara spp eggs, but positive for E. coli. This result suggests that the detection of Toxocara spp eggs would be useful as a qualitative indicator of fecal contamination: (1) Toxocara spp eggs are contained in feces, and (2) unlike E. coli, the number of eggs do not increase in the soil.
