Can You Eat Crab While Pregnant?
Yes — fully cooked crab is low in mercury and safe in pregnancy.
The full answer
Cooked crab is a low-mercury shellfish and counts toward your recommended 8–12 oz of low-mercury seafood per week. It's a good source of protein, omega-3s, and minerals like zinc and selenium. The rules are the usual seafood ones: it must be thoroughly cooked (no raw crab), and if it's pre-cooked and chilled, reheat it until steaming hot. Avoid the brown meat in large quantities if you've been advised to watch cadmium, and steer clear of crab from untrusted sources. Cooked crab in a cake, bisque, or a hot dish is a healthy choice.
How to eat crab safely
- Eat fully cooked — never raw crab
- Reheat chilled cooked crab until steaming hot
- Counts toward ~8–12 oz low-mercury seafood per week
When to avoid: Avoid raw crab and undercooked shellfish; go easy on large amounts of brown crab meat.
Crab by trimester
| Stage | What changes |
|---|---|
| First trimester | Thoroughly cooked crab is generally considered a good choice — it's low in mercury and a useful protein source. The caution is about raw or undercooked shellfish, and about anything that hasn't been kept properly chilled. |
| Second trimester | Unchanged, and this is often when appetite returns and seafood becomes appealing again. Cooked and hot is the standard to hold to. |
| Third trimester | Same guidance. Cold pre-prepared seafood from a counter is the situation to be most careful about, because of how it's been stored rather than what it is. |
Common questions about crab in pregnancy
Is crab safe to eat during pregnancy?
Properly cooked crab is generally regarded as one of the lower-mercury seafood choices and is commonly recommended. What to avoid is raw or undercooked shellfish, and anything that may have sat at the wrong temperature.
What about imitation crab or crab sticks?
These are usually made from cooked processed white fish, so the raw-seafood concern doesn't apply in the same way. They're often high in salt and low in the nutritional benefit of real crab, which is the more relevant point.
Is there a limit on how much I should eat?
General seafood guidance in pregnancy suggests a couple of portions a week, favouring low-mercury species — which crab generally is. Some advice also suggests moderating brown crab meat specifically. Your provider or local food-safety guidance can give you the figure that applies where you live.
Pregnancy food-safety basics
Most “can I have this?” questions in pregnancy come down to four things. Listeria — a bacterium that survives the fridge — is why chilled ready-to-eat meats, pâté, and mould-ripened soft cheeses are heated or avoided. Mercury is why certain fish are limited. Caffeine is capped at about 200 mg a day. And alcohol is best avoided entirely, as no safe amount is known. Cooking food until it’s steaming hot kills listeria and most other bugs, which is why “heat until steaming” solves so many of these questions.
