## 根因

鲭科鱼类（金枪鱼、鲭鱼、鬼头刀、蓝鱼、沙丁鱼）含有高水平的组氨酸；温度控制不当会使细菌将组氨酸转化为组胺，组胺耐热，不会因烹饪或冷藏而破坏；组胺中毒（鲭鱼中毒）会在几分钟到几小时内引起面部潮红、头痛、恶心和低血压。

## 解决方案

1. ```
   Store fresh scombroid fish at 40°F (4°C) or below from the moment of purchase. Cook within 2 days, or freeze immediately. For leftovers, refrigerate within 2 hours of cooking and consume within 2 days. Discard any fish that has been at room temperature for more than 2 hours total.
   ```
2. ```
   If you suspect histamine poisoning (symptoms within 2 hours of eating: flushing, headache, nausea, diarrhea), seek medical attention immediately. Antihistamines (e.g., diphenhydramine) can relieve symptoms. Report to local health department.
   ```

## 无效尝试

- **** — Smell test fails because histamine does not produce a strong odor; the fish may smell normal even when histamine levels are dangerously high. (70% 失败率)
- **** — Reheating the fish to 165°F fails because histamine is heat-stable and remains toxic after cooking. (85% 失败率)
- **** — Freezing the fish fails because histamine is not destroyed by freezing; it can accumulate during initial temperature abuse and persist in frozen storage. (75% 失败率)
