Cystercosis is the most frequently detected pathology in post mortem inspection in bovine slaughtered at establishments under the Federal Inspection Service (SIF). In Brazil, the average prevalence of this parasitosis is 5%, but the rates can vary according to the anatomic area screened, the geographic region, or the period of time the work was carried out. In order to find out the prevalence of this pathology among bovine, in the State of Parana-Brazil, a six months research was carried out – from July to December, 2000 – in animals originating from 137 towns and slaughtered in the Argus Cold Store, located in the Metropolitan Area of Curitiba. The prevalence of positive animals found with Cysticercus bovis varied from 0 to 27.27% with an average of 3.83% among the 26 465animals inspected. The towns with larger numbers of slaughtered animals had an apparent prevalence in allotment between 2.8% to 5%. Regarding sex, a 3.81% rate was found among males and 3.93% among females, but no parasitary specificity or preference were detected. All cystercercus found alive were submitted to the desinvagination process, staining with acetic carmin, and microscopic identification evidencing that 100% were C. bovis. The epidemiological implications of these findings are discussed in the present work.
