根因分析
布鲁氏菌（流产布鲁氏菌和羊布鲁氏菌）即使在卫生良好的农场，也会存在于受感染牛或羊的生奶中，引起波状热、关节炎和潜在的长期残疾；巴氏杀菌（161°F 持续 15 秒）是唯一可靠的灭活方法。
English
Brucella abortus and Brucella melitensis persist in raw milk from infected cattle or goats even in clean farms, causing undulant fever, arthritis, and potential long-term disability; pasteurization (161°F for 15 seconds) is the only reliable inactivation method.

-
Use only pasteurized milk from a licensed dairy; verify pasteurization label (e.g., 'Grade A Pasteurized'). For raw milk, heat to 161°F (72°C) for 15 seconds using a sous-vide circulator with verified thermometer.
-
Substitute with ultra-high temperature (UHT) milk, which is shelf-stable and eliminates all pathogens including Brucella.
无效尝试
常见但无效的做法:
-
70% 失败
Boiling may not reach consistent temperature throughout; uneven heating can leave Brucella viable. Also destroys beneficial enzymes and vitamins, misleadingly implying safety.
-
95% 失败
Brucella does not significantly alter milk pH; absence of sour smell or curdling does not indicate pathogen absence.
-
60% 失败
Testing may miss early infections or intermittent shedding; even vaccinated cows can shed bacteria. No home test can guarantee safety.
