Introduction: Brucellosis is a zoonotic disease, acquired through direct or indirect contact with infected animals. In humans, the symptoms are non-specific and often confused with other infectious diseases. Objective: To verify the seroprevalence and risk factors associated with bovine brucellosis transmission to humans. Methods: A cross-sectional study carried was out in municipalities in the Southern Region of Santa Catarina state. Blood was collected to serum obtentions for laboratorial diagnosis using the Indirect Immunoenzymatic Assay (ELISA) method and a questionnaire was used to collect sociodemographic data and risk factors. Results: Among the 139 participants included in the study, the seroprevalence was 14.4%. Prevalence of seropositive individuals living in the municipalities of Gravatal (25%). There was predominance of males (60%), mean age of 51.7 (± 15.6) years, level of primary schooling (60%), beginning of childhood activities (75%), occupational contact (80%) and time on property for more than five years (90%). The prevalence of unpasteurised milk (90%), boiled milk (89%), fresh cheese (91% and food with cheese (92%) was predominant). Predominance was manual milking (74%), contact with aborted placenta or fetus (88%) and non-use of Personal Protective Equipment (PPE) (80%). In the seropositive participants, symptoms were predominant: weight loss (19%), intermittent fever (17%), Seventy (70%) and profuse sweating (15%) were included in the study, with a median herd of 20 animals, predominantly of small breeders (57%), females (79%) and breeding animals susceptible to brucellosis (80 %), especially dogs (60%). Conclusion: It is concluded that the seroprevalence of brucellosis is high in relation to other studies carried out in Brazil and the non-specific symptoms make diagnostic suspicion difficult. An approach to the interaction between animal and human health can reduce the risk of dissemination and improve the diagnosis of brucellosis in humans.
