Abstract

Bovine cysticercosis is a zoonotic parasitic infection caused by the larval stage (Cysticercus bovis) of Taenia saginata. This study aimed to identify prevention and control measures for bovine cysticercosis indicated by experts in the fields of public and animal health. The study was conducted through three rounds of the Delphi method and had the participation of 44 experts from 13 Brazilian states in 30 educational institutions, research institutions, and sanitary inspection services. The first round comprised an open question, the answers to which formed the basis for structuring the second and third questionnaire. To reach a consensus in the second and third rounds, experts were asked to express their agreement or disagreement of each proposition on the questionnaire using a five-point Likert scale. A descriptive statistical analysis was performed at the end of each round. Twenty-three specialists (52.27%) participated in all three rounds. The first round resulted in 28 proposals categorized into six areas: health education, methods of diagnosis and treatment, sanitation measures, epidemiological studies, legislation and sanitary supervision, and intersectorality. In the second round, the experts reached a consensus on 16 propositions (57.14%). This percentage increased by 3.54% during the third round. At the end of the third round, the experts had reached a consensus on 17 of the 28 initial propositions (60.71%). The highest percentage of agreement (29.4%) was observed in the category of health education. This study allowed us to identify 17 recommendations pertaining to the prevention and control of bovine cysticercosis. These measures are not mutually exclusive, and require an integrated approach to the establishment of intervention actions at various points in the life cycle of the parasite.
