2023年南部某畜牧場檢出羊隻布氏桿菌事件防治經驗

Prevention and Control of Brucellosis following Detection in Goats at a Southern Taiwan Livestock Farm, 2023

2023年12月農業部於南部某乳羊場常規監測時檢出3頭乳羊布氏桿菌陽性，為我國30餘年來首起本土動物布氏桿菌陽性報告案。相關單位進行牧場背景調查、接觸者評估及追蹤、牧場動物防治工作與環境消毒等措施。接觸者經持續2個月的健康追蹤，牧場其餘羊隻則進行每六週且持續3次的抽血檢驗，於監測期滿時，接觸者皆無出現疑似症狀，牧場亦無再檢出陽性羊隻。布魯氏菌病為人畜共通疾病，主要經由受布氏桿菌汙染的食品或未經消毒殺菌的奶類製品而感染，實驗室、屠宰場或肉類包裝廠人員可能經由接觸或吸入病原菌而感染，人傳人情況較為少見，因此只要落實相關防疫措施，出現疑似症狀時提高警覺，及早鑑別診斷，將能有效早期診斷疾病及防止疫情的擴散。

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.
