根因分析
冷冻不会杀死甲型肝炎和诺如病毒等病毒；这些病毒可以在-20°C下存活数月，并在免疫受损人群中引起严重疾病；与冷冻浆果相关的疫情已有充分记录
English
Freezing does not kill viruses like Hepatitis A and Norovirus; these viruses can survive for months at -20°C and cause severe illness in immunocompromised individuals; outbreaks linked to frozen berries are well-documented

-
Advise immunocompromised users to cook frozen berries to at least 185°F (85°C) for 1 minute to inactivate Hepatitis A and Norovirus. Use in cooked applications like compote, jam, or baked goods.
-
Provide alternative: use pasteurized frozen berries (look for label indicating heat treatment) or buy berries that are individually quick-frozen (IQF) with known source, but still recommend cooking for immunocompromised.
-
If user must eat raw, recommend using berries from countries with low Hepatitis A prevalence (e.g., Canada, Northern Europe) and check for recall history, but still warn that risk remains.
无效尝试
常见但无效的做法:
-
Tell user to rinse frozen berries with water before eating
95% 失败
Rinsing does not remove viruses that are embedded in berry surface or under skin; Hepatitis A is highly resistant to washing
-
Suggest buying organic frozen berries
90% 失败
Organic certification does not guarantee virus-free; Hepatitis A outbreaks have been traced to organic frozen berries
-
Recommend soaking berries in vinegar solution
85% 失败
Vinegar may reduce some bacteria but does not inactivate Hepatitis A or Norovirus at household concentrations
