Abstract Background Bovine fascioliasis is a parasitic disease that affects cattle. It leads to direct and indirect great economic loss due to animal mortalities, growth retardation and expenditure on anthelmintics, reduction livestock productivity and essentially condemnation of infected liver by inspection service. The study was carried out to determine the seasonal prevalence and estimated financial losses of fascioliasis in cattle in the Western Highlands of Cameroon. Methodology A total of 2167 cattle were selected. Later, the cattle, have being the carcasses, were dissected, and the livers were dissected and carefully examined for adult liver flukes. Faeces were collected immediately after the cattle were killed and examined using the formol‐ether concentration technique. Condemned livers were weighted to estimate the financial losses using the average price of a kilogram of liver. Results A total 428 of cattle were found with infected livers or egg in the faeces giving a total prevalence of 19.75%. Among the infected carcass, 18.64% had both the Fasciola eggs in the faeces and flukes in the liver while 1.10% had only flukes in the liver. Results revealed that prevalence of Fasciola spp. was significantly higher during the rainy season (23.48%) than 16% in the dry season (p = 0.00). A significantly (p = 0.000) higher prevalence was also observed in females (33.9%) than in males (13.1%). Age range showed significant (p = 0.000) influence with the animals of 8–10 years old recorded the highest prevalence of 39.3%. Furthermore, 433.1 kg of liver was condemned giving a direct financial loss of 1221,550 FCFA (2049.64 USD) and an annual financial loss due to liver condemnation estimated to 1814,775 (3045.01 USD). Conclusion Findings of this study indicated that bovine fascioliasis is prevalent in cattle in the Western Highlands of Cameroon, and it leads to an important financial loss particularly in the rainy season.
