根因分析
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。
English
Freezing does not kill norovirus or hepatitis A virus; these viruses can survive months at -20°C and are not removed by rinsing, requiring heating to 90°C for 2 minutes for inactivation.

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