Contamination of selected recreational areas in Lublin Province, Eastern Poland, by eggs of Toxocara spp., Ancylostoma spp. and Trichuris spp.

INTRODUCTION
While using recreational areas, people take with them accompanying animals (dogs, cats). These animals are the main source and reservoir of dangerous zoonoses, including parasitoses caused by genera of nematodes, also called roundworms, Toxocara spp., Trichuris spp. and Ancylostoma spp. Attention should also be paid to the possibility of contamination of recreational areas with the eggs of intestinal parasites by wild animals (e.g. red fox).


MATERIAL AND METHODS
Sand was collected on beaches and leisure terrains located in recreational areas in Zwierzyniec, Rudka reservoir on the river Wieprz, 'Echo' reservoir, accessible to tourists to the Roztocze National Park, and the 'Florianiecki' reservoir, chich is inaccessible to tourists due to its location in the depths of the National Park. Material for the research was also collected from the 'Zemborzycki reservoir in Lublin, A total of 300 sand samples were collected. The samples, approximately 500 g each, were collected into plastic bags from the superficial layer of sand, at a depth up to 3 cm. For egg detection, flotation with the Wasylikowa metod and the modified Quinn method were used. In the Quinn metod, the flotation solution is NaCl saturated solution, in the Wasylikowa method, 5% solution of NaOH is used.


RESULTS
The most contaminated grounds were areas by the water 'Zemborzycki' reservoir in Lublin. The eggs of intestinal parasites were isolated from 13 out of 24 samples examined. In sand collected from the beach by the 'Echo', 'Florianiecki' and 'Rudka' water resevoirs in Zwierzyniec, no eggs of intestinal parasites were detected.


CONCLUSIONS
Such a dissemination of results may indicate a connection between the degree of occurrence of geohelmint eggs and the intensity of human movement, together with accompanying animals, in places that can be used for recreation.
