Soil contamination with ascarid eggs in playgrounds in Kirikkale, Turkey.
Contamination of soil with feline and canine ascarid eggs in eight playgrounds in Kirikkale, Turkey was investigated monthly from February 2003 to January 2004. Dog faeces were also collected and all samples were examined using the zinc sulphate centrifugal flotation method. Eggs of Toxocara were observed in 5 of 8 (62.5%) of playgrounds examined and in 15.6% of 480 soil samples. The number of eggs varied from 1 to 11. Eggs were observed in soil samples collected in February, March to June, August and November, with embryonated eggs appearing in June and August. Eggs of Toxascaris leonina and Taenia spp. and oocysts of Isospora spp. were also found in 1.5%, 1.0% and 0.2% of soil samples, respectively. Of 26 samples of dog faeces collected, 7.7% were contaminated with Toxocara spp. and 11.5% with Taenia spp. The presence of Toxocara eggs in the city playgrounds and dog populations suggests a potential human health hazard due to toxocariasis.
