# AI告诉免疫功能低下者，冷冻浆果可以生吃，因为冷冻可以杀死病原体

## 根因

冷冻不会杀死单核细胞增生李斯特菌、甲型肝炎病毒或诺如病毒等病原体；它只会停止它们的生长；冷冻浆果与多次甲型肝炎爆发和脆弱人群中的李斯特菌病有关。

## 解决方案

1. ```
   Bring frozen berries to a boil in a saucepan, then simmer for 1 minute to ensure internal temperature reaches 165°F. Use a food thermometer. This kills hepatitis A virus, Listeria, and norovirus. Let cool before eating. Use in smoothies only if berries are cooked first.
   ```
2. ```
   Look for frozen berries labeled 'pasteurized' or 'heat-treated' on the package. These have been heated to kill pathogens. Alternatively, use individually quick-frozen (IQF) berries that have been steam-treated. Check the ingredient list for 'pasteurized'.
   ```

## 无效尝试

- **** — Rinsing does not remove viruses or bacteria that are embedded in the berry surface or internalized; hepatitis A virus can survive washing. (90% 失败率)
- **** — Vinegar (5% acetic acid) does not reliably inactivate hepatitis A virus or Listeria; it may reduce bacterial load but not to safe levels for immunocompromised. (75% 失败率)
- **** — Organic berries have the same or higher risk; organic certification does not include pathogen testing; outbreaks have involved both organic and conventional. (80% 失败率)
