Hepatic dystomatosis, also known as Fascioliasis, is a parasitic disease of herbivorous animals, especially of the bovine and zoonotic species. Therefore, it was proposed to collect information from the literature on liver dystomatosis or fascioliasis in bovines, zoonoses and risk factors and public health interest, in the same way to analyze the number of cases through a retrospective study on the prevalence of livers seized by the presence of the Fasciola hepatic parasite in the Ambato Municipal Camal between the years 2019, 2020, 2021 (first semester). The methodology that was used was exploratory and descriptive through a bibliographic review of scientific articles published in different databases published by various authors, which allows obtaining information on liver dystomatosis or fascioliasis. The entire population of cattle that came to be slaughtered was taken; In the year 2019 of 21,276, in 2020 of 12,396 this decreased due to restrictions of the COVID-19 pandemic and by 2021 (first semester) of 6,570 cattle. The data were placed in contingency tables, the prevalence of hepatic distomatosis or fascioliasis was analyzed, for the year 2019 of 7.96%, for 2020 of 7.21% and for 2021 of 6.49%; With an average of the three years of 7.22%, in this way the existence of Distomatosis in the Camal Municipal de Ambato-Ecuador is demonstrated; It is recommended a plan on the management, prevention and control, treatment and eradication of this parasite and make the population aware of the risk factors.
