Abstract：

        In December 2023, routine surveillance by the Ministry of Agriculture detected Brucella infection in three goats at a southern Taiwan livestock farm, marking the first animal brucellosis cases in over 30 years. Local authorities undertook comprehensive investigations of the farm, assessed and monitored all human contacts, implemented animal disease control measures, and conducted environmental disinfection. Human contacts were subjected to health monitoring over a two-month period, while the remaining goats on the farm underwent serological testing every six weeks for a total of three rounds. At the conclusion of the surveillance period, none of the human contacts developed symptoms or signs related to Brucella infection, and no more positive goats were detected on the farm. Brucellosis is a zoonotic disease primarily transmitted through food contaminated with Brucella or the consumption of unpasteurized milk. Laboratory workers, slaughterhouse personnel, and meatpacking plant workers are also at risk of infection through direct contact with or inhalation of the pathogen. While human-to-human transmission is rare, the disease can be effectively contained by implementing appropriate preventive measures, conducting symptomatic surveillance, and ensuring early identification and diagnosis.
