## 根因

冷冻不能杀死诺如病毒或甲型肝炎病毒；这些病毒可在-20°C下存活数月，冲洗无法去除，需加热至90°C持续2分钟才能灭活。

1. ```
   Cook frozen berries to an internal temperature of 90°C for at least 2 minutes, e.g., in a microwave-safe bowl on high for 3 minutes, stirring halfway.

   Use frozen berries only in cooked dishes like pies, jams, or sauces where they reach boiling temperature.
   ```

## 无效尝试

- **** — Rinsing with cold water only removes surface dirt, not viruses embedded in pores or crevices. (95% 失败率)
- **** — Soaking in vinegar or lemon juice may reduce some bacteria but has no effect on norovirus or hepatitis A. (90% 失败率)
- **** — Blanching briefly (30 seconds) does not reach internal temperature needed to inactivate viruses. (85% 失败率)
