Sanitary and parasitological condition of environmental objects of the Astrakhan Region

Abstract

The article presents the sanitary-parasitological state of environmental objects of the Astrakhan region for 2022. In 2022, 6246 samples taken from various environmental objects were examined, the number of samples that did not meet sanitary-parasitological indicators was 0.7 % (41 samples): toxocar eggs — 17 samples, strongylid larvae (mobile and immobile) — 19 samples, ascarid eggs (fertilized) — 5 samples. The largest number of samples accounted for flushing from solid household surfaces — 76.7 % (4790 samples), of which only 0.02 % (1 sample) revealed ascaris eggs (fertilized). The second place in the number of samples studied belongs to samples of water bodies — 8.1 % (505 samples), of which 2.2 % (11 samples) did not meet sanitary and parasitological indicators: strongylid larvae (mobile and immobile) were detected — 8 samples, toxocar eggs — 2 samples and ascaris — 1 sample. Samples of food products and food raw materials made up almost the same number of samples — 8.1 % (503 samples), of which 3.2 % (16 samples) were samples that did not meet parasitological indicators. As a result of the work done, the results were obtained: the parasitic contamination of environmental objects in 2023 remains very unfavorable. Contamination of water of surface reservoirs, soil and sand with helminthiasis pathogens may indicate that these objects were contaminated with feces of infected animals and humans, or about the fact of accidents on the sewer network and the likely ingress of helminthiasis pathogens from outside. The presence of parasites in food samples may indicate contamination of the water used for irrigation or contamination of the soil with the feces of infected animals and humans.
