Fasciolosis remains a frequent parasitosis within the bovine in extensive, despite the great implantation and efficacy of fasciolicides drugs. In the present work, the prevalence of Fasciola hepatica has been studied for five years, analyzing 251 cattle in the fight, evaluating the presence of hepatic macroscopic lesions. In turn, its relationship with the average temperature and rainfall of the year, and describe its pathophysiological consequences during the bullfighting celebration. Methodology: it was carried out in Madrid (July-September 2013-2017). Results: n = 251 animals in the five years, 50.20 ± 2.68 evaluated per year, of which 14 had lesions, on average 2.80 ± 1.64 per year. Likewise, a total of 4 animals compatible with lesions in the five years, on average 0.80 ± 0.84 animals per year, were reviewed. The average annual temperature was 15.78 ± 0.48 °C and the average annual rainfall was 570.20 ± 102.21mm. Statistical correlation is observed between the channels with lesions and the average annual rainfall (P <0.01) and with the average annual temperature (P <0.05). Average prevalences (5.61 ± 2.82) are lower than those described by different authors, together with weather conditions compatible with the growth of the parasite and all its intermediate hosts. The study reveals that a good use of antiparasitic agents is not entirely effective in this type of farms.
