    Opis:
    The flotation method elaborated for recovery of Toxocara and other geohelminth eggs from soil is described. Soil samples of about 500 ml volume are picked from 3-cm superficial layer of the ground. In the laboratory, 40 g of dry and sifted material is analysed according to following procedure: 1 h standing, 20 minutes shaking and 3 minutes centrifugation (1500 rpm) in 5% sodium hydroxide (NaOH), then centrifugation, like above, with H₂O for washing the sample and next with the saturated sodium nitrate (NaNO₃) for flotation the eggs. Specimen is prepared by placing a cover slip on the positive meniscus of the flotation liquid.

    Opis:
    Organic farming, despite being more difficult and labour consuming than traditional farming, gains increasingly more followers among farmers. Currently in Poland there are approximately 10 000 organic farms. Pure, uncontaminated soil in the Lublin voivodeship makes this area an ideal location for organic agriculture production. In 2006–2007, 102 soil samples were examined from 40 organic farms specializing in vegetables and berries. Farms for the study were selected by ecology- and food-production specialists from the Lublin Agriculture Advisory Centre in Końskowola. The following plants were cultivated on the farms examined: berry-bearing plants, carrots, parsley, zucchini, cabbage, lettuce, cucumbers, cauliflowers, leeks, onions, kidney beans, beetroots, potatoes, pumpkins, broad beans, rhubarb and herbs. The presently reported parasitological survey was performed on 102 soil samples. Each sample consisted of 100 g of soil and the methodology followed that of the Polish Standard PN-Z-19000-4 (flotation method by Quinn et al.). The survey yielded eggs of parasites representing genera: Ascaris, Trichuris and Toxocara. Contamination with eggs of intestinal parasites was noted in 43 (42.16%) soil samples. Toxocara spp. eggs were found in 24 samples (55.81%). Eggs of Ascaris spp. were detected in 18 samples (41.86%) while eggs of Trichuris spp were present in one sample (2.32%). In total, 29 eggs of Toxocara spp., 19 eggs of Ascaris spp., and 1 egg of Trichuris spp. were found. The largest amount of soil for examination was taken across the plantations of berry-bearing plants – 57 samples. In the group examined, plantations of raspberries and strawberries dominated. The soil was contaminated with the eggs of Toxocara spp. and Ascaris spp. No eggs of Trichuris spp. were detected. The presence of eggs of intestinal parasites in soil poses a threat of geohelminthoses to people who eat contaminated fresh fruits and vegetables.

    Opis:
    The main source of many zoonoses is soil contaminated with feline and canine faeces. The aim of this study was to examine the degree of soil contamination with geohelminth eggs in the area of Wrocław. Within 2006–2007 a total of 185 soil samples (parks, backyards, playgrounds and city squares) from area were collected and then examined using flotation technique in saturated sodium nitrate. The helminth eggs were found in 37 (20%) samples. The highest rate of contamination was in the city squares (38.2%). The eggs were also found in 29.1% of backyards. Parks and playgrounds with sandpits were free of any contamination. The prevalence of helminth eggs in positive samples was as follows: Toxocara spp. 3.2%, Uncinaria stenocephala 7.0%, Ancylostoma caninum 4.9% and Trichuris vulpis 4.9%.
