According to the Federal Service for Supervision of Consumer Rights Protection and Human Welfare, opisthorchiasis is a dangerous social threat to Russia today. The Russian Federation territory contains two-thirds of the world area of the causative agent of opisthorchiasis [1]. The largest natural focus of opisthorchiasis is the Ob-Irtysh region, it includes the Khanty-Mansiysk Autonomous Okrug-Yugra, which became the object of this study.
According to the Rospotrebnadzor Administration for the Khanty-Mansiysk Autonomous Okrug - Yugra, parasitic diseases remain one of the leading pathologies in the region, despite the noted downward trend in the prevalence over the past few years.
According to surveys conducted by the study [3], about one fifth of people with acute opisthorchiasis became infected after eating fish that was bought in stores and supermarkets.
The purpose of this work was to assess the extent of invasion of cyprinid family fish, purchased in some chains of grocery stores in Khanty-Mansiysk.
The study was conducted during the first half of 2019. During this time, a survey of 243 fish specimens, among which were ides, daces and roach, was carried out.
The abundance index, extensiveness and intensity of invasion were calculated to analyze the materials obtained in the course of this study [4].
All fish were bought as roach, but during the work it was determined that under the guise of roach, shops also sell ides and daces, the differences in which are difficult to determine, and at fishery enterprises on an industrial scale, all these species are sold as roach.
During the study, it was found that no roach has opisthorchid metacercariae, while the extent of invasion of ides and daces is 100% for all ages of the studied fish.
Based on the obtained results, it can be concluded that of all the studied cyprinid family fish, roach is the least susceptible to invasion by opisthorchid metacercariae, which is possibly related to the difference in the structure of muscle tissues and scales. Roach is mistakenly attributed to high rates of invasiveness, confusing it with similar fish species - dace and ide.
