Abstract

Contamination of 13 sandpits in public parks in Hyogo Prefecture, Japan, by Toxocara eggs and animal faeces was studied. All 13 sandpits were contaminated with faeces. The mean number of faeces found in 1 m2 of the sandpits was 35, from which the number of faeces in each sandpit was estimated to be 261 to 2205. Toxocara eggs were detected in 12 of the 13 sandpits, each examined 4–15 times; the overall prevalence was 92%. The eggs were not always distributed in the same pattern, but in general, eggs were numerous on the sandpit surface but also present at depths of about 35 cm. Of the eggs recovered, 63% were fully embryonated. Of the 13 sandpits examined, two were heavily contaminated by eggs, and all but one of the others were mildly contaminated. The difference between heavy and light contamination was not related to differences in the environment or in the number of faeces; the cause is unknown.
