根因分析

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。

English

Bacillus cereus spores can survive cooking and germinate if rice is left at room temperature for too long; reheating may not destroy the heat-stable toxins produced by the bacteria, leading to vomiting or diarrhea.

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

常见但无效的做法:

  1. 90% 失败

    Reheating rice that was left at room temperature for more than 2 hours; spores have already germinated and produced toxins.

  2. 85% 失败

    Believing that steaming hot reheating kills all bacteria; toxins are heat-stable and survive reheating.

  3. 70% 失败

    Storing rice in the fridge for several days and then reheating; toxin can still form if cooling was slow.
