Abstrakt:	The present study aimed to assess the prevalence and risk factors associated with bovine brucellosis in slaughterhouses in the state of Ceará using spatial distribution and flow network analysis. Four slaughterhouses were sampled in Ceará: two under municipal inspection and two under state inspection. Blood samples were randomly collected from bovine animals, resulting in a total of 964 samples. The collected sera were subjected to the Acidified Buffered Antigen (AAT) test, and the complement fixation test (FC) was performed for positive cases. An epidemiological questionnaire was applied to 38 producers who slaughter animals at the sampled facilities to assess the risk factors for brucellosis. An apparent prevalence of 1.55% (15) was found in the AAT test and 0.2% (n=2) in the FC test. A higher percentage of reactive animals was observed (66.6%) in properties where cattle farming is not the main activity, with OR = 4.75. The absence of contact with neighboring animals is a factor associated with protection, with a lower prevalence of seroreactive animals (23.5%) when animals were raised without contact with others (OR = 0.30). Therefore, bovine brucellosis in herds and animals can be considered low in the studied region and under all production systems. Nevertheless, despite the importance of this disease to the economic and public health aspects and the advances of the PNCEBT Program, brucellosis is still circulating in Ceará.
