Eating shellfish in pregnancy is generally safe as long as it's been cooked1. But if you're a fan of raw oysters, you might have to choose an alternative dish from the menu. Raw shellfish may be contaminated with harmful bacteria and viruses, and therefore carries a higher risk of food poisoning.
Why can't I eat shellfish when pregnant?
You should avoid raw shellfish because they can have harmful bacteria, viruses or toxins in them. These can make you unwell and give you food poisoning.
What seafood should you avoid when pregnant?
Never eat shark, swordfish, king mackerel, or tilefish. Limit lower-mercury fish, such as canned light tuna, shrimp, salmon, catfish and tilapia, to 12 ounces (two average meals) a week. Albacore “white” tuna has more mercury than canned light tuna, so limit your intake to one serving (six ounces) per week.
