Yes, you can usually eat crawfish while pregnant as long as it is fully cooked, eaten in moderation, and part of your overall weekly seafood limit.

Is crawfish safe in pregnancy?

  • Crawfish is considered a low -mercury seafood, with an average mercury level around 0.033 ppm, well below the FDA’s “low” cutoff of 0.1 ppm.
  • Health resources and dietitians note that fully cooked crawfish is generally safe for pregnant people and can be part of a healthy prenatal diet.

How much crawfish can you eat?

  • Many pregnancy and nutrition guidelines recommend keeping total low‑mercury seafood (including crawfish) to about 12 ounces per week, usually 2–3 servings.
  • Because crawfish are small, it is easy to eat a lot at a boil, so paying attention to portion size helps you stay within weekly seafood recommendations.

Safety tips for eating crawfish

  • Crawfish should be thoroughly cooked to an internal temperature of at least 145°F; undercooked seafood can carry bacteria and parasites that increase the risk of foodborne illness in pregnancy.
  • Avoid crawfish that looks raw, translucent, or rubbery, and skip dishes where you are unsure how long it sat at room temperature (like buffets or long outdoor events).
  • Some sources advise avoiding imported crawfish because mercury and contaminant levels are harder to verify; U.S.-sourced, well-regulated seafood is preferred.

Benefits of crawfish during pregnancy

  • Crawfish is a lean source of protein , with around 14 grams per serving and relatively low total and saturated fat, which supports healthy growth and helps you feel full.
  • It also provides useful micronutrients for pregnancy, including iron, B vitamins, selenium, copper, and small amounts of vitamins A and C.
  • A typical serving is fairly low in calories (around 70 per serving reported by one hospital source), making it a nutrient-dense option.

When to be extra cautious or avoid it

  • Skip crawfish if you have a shellfish allergy, past reactions to crustaceans, or if you develop new allergy‑like symptoms during pregnancy.
  • Avoid visibly spoiled, foul‑smelling, or improperly stored crawfish, as pregnancy increases vulnerability to food poisoning.
  • If you have complications such as gestational hypertension, gestational diabetes, or are on a special diet, your doctor or midwife may suggest more specific limits tailored to you.

Bottom line: Fully cooked, properly handled crawfish in moderate amounts is generally safe in pregnancy and can provide protein and key nutrients, but it should fit within your overall 12‑ounce weekly low‑mercury seafood limit and any personalized advice from your prenatal provider.
