Abstract:	Bovine brucellosis is an infectious zoonosis with a worldwide distribution, which affects livestock productivity and poses an important risk to human health. This study aimed to analyze the epidemiological situation of bovine brucellosis in the state of Goiás, 15 years after the implementation of the compulsory vaccination of heifers. We carried out a random seroprevalence survey and investigated the association of cattle production and management systems with brucellosis. Moreover, we analyzed data on human brucellosis to identify possible associations with brucellosis in cattle. The state was divided into three regions for sampling and inference purposes and, in total, 9,422 females over 24 months were tested on 898 farms. The prevalence of brucellosis in cattle herds in the state of Goiás was estimated at 18.7% (95% CI: 16.12 - 21.36%), with an animal prevalence of 3.9% (95% CI: 2.77 – 5.02%). The variables identified as risk factors in a logistic regression model were: Herds with more than 90 adult females (OR = 2.02, 95% CI: 1.4 - 2, 9; p≤ 0.001) compared to smaller herds; beef herds (OR = 3.58; 95% CI: 2.18 - 5.8; p≤ 0.001) and dual-purpose herds (OR = 2.0; 95% CI: 1.2 - 3.29; p = 0.006), when compared with dairy herds. As for the characterization of the cattle properties in Goiás, low-tech and extensive farming predominate. There is little use of artificial insemination in reproductive management, with dairy herds showing the highest levels of technification. Only two human cases of brucellosis were confirmed between 2013 and 2017 in the state of Goiás, which may be partially justified by the low sensitivity of the health surveillance system. The results of this study demonstrate the persistence of infected animals in cattle herds in the state, with no favorable evolution since 2002, after more than a decade of implementation of the mandatory heifer Bovine brucellosis is an infectious zoonosis with a worldwide distribution, which affects livestock productivity and poses an important risk to human health.
