Can you eat ganjang gejang while pregnant?
Not advisedNo, avoid ganjang gejang while pregnant. The crab is raw and only marinated in soy sauce, so it carries Listeria, Vibrio and parasite risks that cold brine does not remove.
Why
Ganjang gejang is live blue crab cured in soy sauce for a day or two, which seasons the meat but never cooks it. The CDC tells pregnant women to avoid raw and undercooked shellfish because Listeria and Vibrio survive in cold, salty conditions, and Listeria infection in pregnancy can lead to miscarriage, stillbirth or newborn infection even when the mother feels only mildly unwell. The NHS puts raw shellfish on its foods to avoid list for the same reason, and soy sauce, garlic and chilli have no reliable killing effect on bacteria or on the lung fluke parasites found in some freshwater crab.
Safer alternatives
- Steamed blue crab served hot
- Spicy braised crab stew, kkotgetang
- Crab fried rice or crab jjim, cooked through
- Pasteurized tinned crab meat in a salad
- Surimi crab sticks, which are fully cooked

Frequently asked questions
Is yangnyeom gejang any safer than ganjang gejang?
No, the red chilli version uses the same raw crab and is simply dressed differently. Both should be left until after birth.
Does freezing the crab first make it safe?
Freezing can kill parasites but it does not reliably kill Listeria or Vibrio, which are the main pregnancy concerns here. Only cooking the crab through makes it safe.
I ate ganjang gejang last week, should I worry?
Most people are fine, and the odds of infection from one meal are low. Keep an eye out for fever, chills, diarrhoea, headache or muscle aches for up to about two months and mention the meal if you get checked.
