Sixty three children, who were living in an area known to be heavily contaminated by dog faeces in the centre of city of Poznan, Poland (Toxocara spp. eggs were found in 53% of 40 g soil samples), were examined for antibodies to Toxocara spp. Five children (7.9%) had high absorbance values in the Toxocara ELISA test. Geophagia and dog's ownership were the major associated risk factors. Neither present nor past symptoms and signs usually related to toxocarosis were found in any of the seropositive children. The study confirmed that toxocarosis may be clinically inapparent even in an area where exposure to infection is common and serological responses well pronounced.
