An investigation was carried out for the presence of Toxocara sp. eggs in some public parcs and sandpits in the city of Utrecht. The pollution of public parcs in this city with T.canis eggs is comparable with reports from other European cities. T.cati eggs were found in relative samll numbers only. Interestingly there was no difference between parcs with or without formal exclusion of dogs. Differences between districts within the city could not be clarified. Sandpits are merely polluted with eggs of T.cati. Incidentally T.canis was found. Sandpits which were obviously kept clean contained lower numbers of eggs than sandpits which were clearly neglected. Some sandpits were closed to exclude animals. If the fence or whatever was used did not fit well, the pollution took place sometimes even more severely than in open sandpits. It was concluded that public sandpits all over the city were contaminated with Toxocara eggs.
