AI tells a user that leftover cooked pasta is safe to eat for up to 5-7 days in the refrigerator, ignoring that cooked pasta can support Bacillus cereus growth and that the FDA recommends discarding after 3-4 days
ID: food-safety/ai-says-leftover-pasta-safe-for-several-days
Root Cause
Cooked pasta is a starchy, moist environment that can allow Bacillus cereus spores to germinate and produce toxins if stored too long, even at refrigeration temperatures; the FDA and USDA recommend consuming cooked pasta within 3-4 days for safety.
generic中文
煮熟的意大利面是一种淀粉质、潮湿的环境，如果储存时间过长（即使在冷藏温度下），可能允许蜡样芽孢杆菌孢子萌发并产生毒素；FDA和USDA建议在3-4天内食用煮熟的意大利面以确保安全。

90% success Refrigerate cooked pasta within 2 hours of cooking and consume within 3-4 days. For longer storage, freeze pasta in airtight containers for up to 3 months.

中文步骤
煮熟的意大利面在烹饪后2小时内冷藏，并在3-4天内食用。如需长期储存，在密封容器中冷冻最多3个月。
如果意大利面已冷藏超过4天，即使看起来和闻起来正常也要丢弃。不要依赖感官判断安全性。
Dead Ends
Common approaches that don't work:
-
65% fail
User thinks refrigeration stops all bacterial growth, but Bacillus cereus can grow slowly at 4°C if stored beyond 4 days.
-
75% fail
User assumes reheating to 165°F kills Bacillus cereus toxins, but the toxins are heat-stable and not destroyed by reheating.
-
50% fail
User thinks adding sauce (e.g., tomato-based) extends shelf life, but sauce does not significantly inhibit Bacillus cereus.
