OJEDA-ROBERTOS, Nadia Florencia et al. Factors associated with the seizure of livers positive to Fasciola sp. in an endemic area of southeastern Mexico. Rev. mex. de cienc. pecuarias [online]. 2020, vol.11, n.2, pp.565-575.  Epub 23-Oct-2020. ISSN 2448-6698.  https://doi.org/10.22319/rmcp.v11i2.5173.

This study aimed to determine the frequency for the seizure of livers with damages attributed to the presence of Fasciola sp. and associated risk factors. It was conducted a prospective observational study with daily visits, for 12 months, to a municipal slaughterhouse in the Sierra area in the state of Tabasco. Of the seized livers, 25.8 % tested positive for the parasite presence; seizure was the same in male and female animals (X2= 0.011, gl= 1, P<0.05). The highest proportion of seized livers was observed during the rainy season (9.36 %). This study concludes that the prevalence of fascioliasis in the Jalapa area has not decreased in recent years and is related to animal origin. Fascioliasis is a disease that must be monitored to detect the factors that allow it to remain in a geographic region, in order to establish and propose strategic control and preventive measures adapted to the particular conditions of endemic areas.
