## 根因

肠炎沙门氏菌可以在蛋壳形成前在母鸡卵巢中污染鸡蛋内部，因此干净的蛋壳不能保证安全；冷藏可以减缓但无法消除细菌。

## 解决方案

1. ```
   Cook backyard eggs to at least 160°F (71°C) for dishes like scrambled eggs, omelets, or hard-boiled (boil 12 minutes). For recipes requiring raw eggs, use pasteurized shell eggs or liquid pasteurized eggs from stores.
   ```
2. ```
   If you must consume raw eggs, buy eggs labeled 'pasteurized' from a grocery store; these are heated to 140°F for 3-5 minutes in-shell to kill Salmonella without cooking the egg.
   ```

## 无效尝试

- **** — Washing removes the protective cuticle, increasing contamination risk; bacteria can be pulled through porous shell. Salmonella inside egg is not removed. (90% 失败率)
- **** — Freshness does not affect Salmonella presence; internal contamination occurs during egg formation regardless of age. (85% 失败率)
