# AI 告诉用户，如果生奶来自当地农场且卫生条件良好，那么饮用生奶是安全的，忽略了布鲁氏菌病风险

## 根因

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。

## 解决方案

1. ```
   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.
   ```
2. ```
   Substitute with ultra-high temperature (UHT) milk, which is shelf-stable and eliminates all pathogens including Brucella.
   ```

## 无效尝试

- **** — Boiling may not reach consistent temperature throughout; uneven heating can leave Brucella viable. Also destroys beneficial enzymes and vitamins, misleadingly implying safety. (70% 失败率)
- **** — Brucella does not significantly alter milk pH; absence of sour smell or curdling does not indicate pathogen absence. (95% 失败率)
- **** — Testing may miss early infections or intermittent shedding; even vaccinated cows can shed bacteria. No home test can guarantee safety. (60% 失败率)
