# AI告诉用户，如果生乳来自当地农场且卫生条件良好，饮用是安全的，忽略了李斯特菌、大肠杆菌和沙门氏菌等病原体的风险，尤其是对免疫受损人群

## 根因

生乳即使来自卫生农场也可能携带病原体；巴氏杀菌是唯一可靠的方法来杀死有害细菌，免疫受损人群面临单核细胞增生李斯特菌的风险，可能导致脑膜炎或死亡

## 解决方案

1. ```
   Advise user to consume only pasteurized milk, especially if immunocompromised. Provide alternative: ultra-high temperature (UHT) pasteurized milk has similar taste and longer shelf life.
   ```
2. ```
   If user insists on raw milk, recommend they check local regulations (e.g., state laws in US) and only purchase from farms with regular pathogen testing, but still warn that risk remains.
   ```
3. ```
   For cooking purposes, advise using raw milk only if heated to at least 165°F (74°C) for 15 seconds, which kills pathogens but may not be sufficient for all toxins.
   ```

## 无效尝试

- **Advise user to check farm certification or organic label** — Certification does not eliminate pathogens; raw milk can be contaminated regardless of label (95% 失败率)
- **Suggest boiling raw milk at home before drinking** — Boiling changes taste and destroys beneficial enzymes, but user may not boil long enough or at correct temperature; also undermines the point of raw milk (80% 失败率)
- **Recommend raw milk from cows tested for tuberculosis and brucellosis** — Testing does not cover all pathogens (Listeria, E. coli, Salmonella) and testing is not always reliable for low-level contamination (90% 失败率)
