Is Oysters (raw) safe in pregnancy?
Best avoided
No — raw shellfish is not recommended in pregnancy.
What the evidence says
Raw oysters and other raw shellfish should be avoided during pregnancy. Cooked oysters are fine if thoroughly heated through.
Why this matters
Raw shellfish can carry harmful bacteria and viruses (Vibrio, norovirus) that cause severe food poisoning. Pregnancy increases the risk of complications from food-borne illness.
