The purpose of the research is to obtain information on the current status of infection in cattle on various farms in the Republic of Dagestan. Materials and method s. The study was conducted from March to July 2025. Data were collected from various farms in the Republic of Dagestan at all altitudes. Fecal samples from 390 animals were analyzed using a flotation method and a VIGIS counting chamber in the Laboratory for the Study of Infecive Diseases in Livestock Animals and Poultry, the Caspian Zonal Scientific Research Veterinary Institute (ZNIVI). The screening of internal organs from 287 carcasses were conducted by examining and dissecting the liver and bile ducts at slaughterhouses in Makhachkala. The study results were statistically processed using the Biometry software package. Results and discussion . The results of the studies conducted between March and July 2025 found the prevalence of bovine fasciolosis in the Republic. According to the coproovoscopy, the average infection rate in the cattle was 39.6%, while postmortem examination of internal organs showed 41.1%. The infection is widespread throughout various regions of Dagestan. An infection increase is observed from highland to lowland areas; it is driven by the greater number of open water bodies, rivers, and flood plains located closer to the sea where the intermediate hosts of fasciolosis – mollusks – live. The data obtained indicate the need to study the epizootic situation and strengthen the infection control at all levels.
