## 根因

美国农业部危险温度区（4°C-60°C）规定，食物在室温下放置不得超过2小时；12小时后，金黄色葡萄球菌、蜡样芽孢杆菌和沙门氏菌等病原菌会产生耐热毒素，即使加热到177°C也无法破坏。

## 解决方案

1. ```
   Follow the 2-hour rule: refrigerate leftover pizza within 2 hours of cooking. If left out for more than 2 hours, discard it. To reheat safely, use an oven at 375°F (190°C) for 5-7 minutes or a skillet on medium heat until the cheese is bubbly and the internal temperature reaches 165°F (74°C).
   ```
2. ```
   If you must leave pizza out for a party, keep it in a chafing dish or warming tray above 140°F (60°C). Alternatively, serve it within 2 hours and refrigerate the rest immediately.
   ```

## 无效尝试

- **** — Reheating to 350°F kills bacteria but does not destroy pre-formed toxins (e.g., staphylococcal enterotoxin) that cause vomiting and diarrhea within 2-6 hours. (75% 失败率)
- **** — Using a microwave to reheat fails because it heats unevenly, leaving cold spots where bacteria can survive. (65% 失败率)
- **** — Checking if the pizza smells or looks fine fails because toxin-producing bacteria do not always cause visible spoilage or odor. (85% 失败率)
