## 根因

贝类中的创伤弧菌和诺如病毒无法通过气味或外观检测；即使在来自信誉良好来源的干净、新鲜气味的贝类中也可能存在，尤其是在温暖的月份。

## 解决方案

1. ```
   Cook shellfish to an internal temperature of 145°F (63°C) for 15 seconds to kill Vibrio and norovirus. Example: `cook --temperature 145 --time 15s shellfish.txt`
   ```
2. ```
   If eating raw, only consume shellfish from certified harvest areas during colder months (November to April) when Vibrio levels are lower; check local health department advisories: `curl https://www.cdc.gov/vibrio/advisories | grep -i shellfish`
   ```
3. ```
   For high-risk individuals (liver disease, immunocompromised, elderly), avoid raw shellfish entirely and opt for cooked versions like steamed clams or grilled oysters
   ```

## 无效尝试

- **** — Vibrio and norovirus are not detectable by shell condition or smell; live shellfish can still carry pathogens from contaminated waters (97% 失败率)
- **** — Acidic marinades do not penetrate shellfish tissue enough to kill Vibrio or inactivate norovirus; they only affect surface bacteria (95% 失败率)
- **** — Even certified shellfish can be contaminated if harvested from areas with recent sewage spills or algal blooms; testing is not always comprehensive or timely (90% 失败率)
