## 根因

沙门氏菌肠炎菌株可以通过母鸡的卵巢污染鸡蛋内部，即使蛋壳干净；冷藏可以减缓但不能杀死沙门氏菌；只有巴氏杀菌（在140°F下加热3.5分钟）或烹饪到160°F才能确保安全。

## 解决方案

1. ```
   Pasteurize eggs at home: place eggs in a sous-vide bath at 140°F for 3.5 minutes, then cool in ice water. This kills Salmonella without cooking the egg. Example: `Sous-vide eggs at 140°F for 3.5 min → ice bath → store refrigerated`
   ```
2. ```
   Cook eggs until both white and yolk are firm (160°F internal). For dishes like Caesar dressing, use pasteurized egg products. Example: `Cook scrambled eggs to 160°F; use pasteurized liquid eggs for raw recipes`
   ```

## 无效尝试

- **Wash the eggs with soap and water before cracking** — Washing removes the protective cuticle and can push bacteria through the shell pores; internal contamination is unaffected (90% 失败率)
- **Use eggs from vaccinated hens or organic farms** — Vaccination reduces but does not eliminate Salmonella; organic farms have higher rates of environmental contamination (75% 失败率)
