Abstrakt: This study investigated the prevalence of bovine liver condemnation due to Fasciola hepatica in abattoirs and its influence on livestock productivity. It also explored risk factors such as season, breed, age and sex in the states of Puebla and Veracruz, Mexico. A total of 5281 cattle livers were inspected in two abattoirs. The overall prevalence of the parasite in cattle throughout 2020 was 24.9% (1313 out of 5281). The highest prevalence was found in Veracruz (28.5%; tropical climate), followed by Puebla (18.4%; temperate climate). The prevalence of fluke infection during the wet season was 19.0% and 25.8% in the states of Puebla and Veracruz, respectively; during the dry season, this was 18.0% and 30.2% respectively. The annual loss caused by condemnation of the liver for both abattoirs was estimated to be US$7502. Using multivariate logistic regression analysis, two models were constructed for potential association with the prevalence of condemned livers, using season, breed, age and sex as risk factors. The results indicate that season, age and sex were significantly associated with an increased risk of parasitic infection. Cattle age was the variable most strongly associated with F. hepatica infection, with the highest prevalence in cattle over three years of age as compared to younger animals, both in the states of Veracruz with a tropical climate (OR 6.443; 95% CI: 4.487-9.251) and in Puebla with a temperate climate (OR 2.854; 95% CI: 1.531-5.321). The results indicate that different factors were significantly associated with the prevalence of condemned livers, and it highlights the importance of continuous monitoring programmes for F. hepatica infection and preventing economic losses in cattle production.
