<p><strong>Materials and methods. </strong>The research work was carried out in the Laboratory of Bacteriological and Parasitological Research of the Center for Hygiene and Epidemiology in the Astrakhan Region in 20102019. A total of 10 692 soil samples were examined, and 11 384 studies were performed. The number of samples, which did not meet the sanitary and parasitological indicators was 7.0 % (753 samples). Eggs and larvae of helminths, as well as cysts of pathogenic intestinal protozoa were found in these samples.</p>
<p><strong>Results.</strong> During the analyzed period, 86 491 samples of sanitary and parasitological studies were selected and examined in the Astrakhan region, of which 93.6 % (80 962 samples) were samples taken from various environmental objects (water, soil, manure, flushes from solid household surfaces). The total share of soil samples in the structure of all studies of environmental objects was 13.2 % (10 692 samples).</p>
<p><strong>Conclusions.</strong> Parasitic contamination of the soil remains tense, as evidenced by positive findings in the form of eggs and larvae of helminths, as well as cysts of pathogenic intestinal protozoa. The presence of toxocara eggs and strongylid larvae in the soil indicates contamination of this object with the feces of infected animals. The presence of eggs of ascarids, opisthorchis, pygmy tapeworm and cysts of dysentery amoeba in the soil may indicate that this object is contaminated with the feces of persons with parasitic infestation, or about accidents on the sewer network and underflooding of soil sampling sites.</p>soileggs and larvae of wormscysts of pathogenic intestinal protozoaToxocarastrongylidaпочваяйца и личинки гельминтовцисты патогенных кишечных простейшихтоксокарыстронгилиды[Galimzyanov H.M., Mirekina E.V., Kuryatnikova G.K., Poluhina A.L., Frank G.N., Bedlinskaya N.R., Akmaeva L.R., Bikbaeva YU.N., Nikeshina T.V.
