## 根因

肉毒杆菌毒素（Clostridium botulinum）在毒素形成后不能通过pH调整中和；只有长时间加热至185°F（85°C）以上5分钟或压力罐装至240°F（116°C）才能破坏毒素。

## 解决方案

1. ```
   If any can is bulging, leaking, or has off-odor, do not open it. Wrap in plastic, place in sealed bag, and dispose in trash that will not be scavenged. Wash hands thoroughly with soap and water.
   ```
2. ```
   Boil the food in a saucepan at a rolling boil for at least 10 minutes (at altitudes above 3000 ft, add 1 minute per 1000 ft). This destroys botulism toxin if present. Use a thermometer to ensure 212°F.
   ```

## 无效尝试

- **** — Acidification after toxin formation does not destroy preformed botulism toxin; it only prevents future growth. (90% 失败率)
- **** — Botulism toxin requires 5+ minutes at 185°F (85°C) or 10 minutes at 176°F (80°C) for inactivation; 1 minute is insufficient. (80% 失败率)
- **** — While correct for canning, this is not a practical fix for already-canned food that is suspected; the food must be discarded. (60% 失败率)
