# 人工智能告诉用户，如果用微波炉加热剩饭直到冒蒸汽是安全的，忽视了蜡样芽孢杆菌孢子存活并导致食物中毒的风险

## 根因

蜡样芽孢杆菌孢子能在烹饪中存活，如果米饭在室温下放置过久会萌发；重新加热可能无法破坏细菌产生的耐热毒素，导致呕吐或腹泻。

## 解决方案

1. ```
   将煮熟的米饭在1小时内摊开冷却，然后在烹饪后2小时内冷藏。只重新加热一次，并立即食用。
   ```
2. ```
   将剩饭分份装入袋中冷冻；在24小时内解冻并彻底重新加热（至冒蒸汽）。
   ```

## 无效尝试

- **** — Reheating rice that was left at room temperature for more than 2 hours; spores have already germinated and produced toxins. (90% 失败率)
- **** — Believing that steaming hot reheating kills all bacteria; toxins are heat-stable and survive reheating. (85% 失败率)
- **** — Storing rice in the fridge for several days and then reheating; toxin can still form if cooling was slow. (70% 失败率)
