Can you eat lobster while pregnant?
Yes, if it is fully cooked, and FDA and EPA list lobster among Best Choices for mercury (mean 0.093 to 0.166 ppm in FDA testing). In pregnancy that allows 2 to 3 servings of 4 oz a week across all Best Choices fish and shellfish combined, with the lobster cooked until the flesh is pearly and opaque, never raw or undercooked.
This page covers food safety in pregnancy. The same advice applies to other people at higher risk of foodborne illness: older adults, young children and people with weakened immune systems. If your doctor has given you a specific diet, follow it. The mercury amounts on this page are for adults who are or may become pregnant or are breastfeeding. FDA and EPA give children different amounts.
What FDA, ACOG and FoodSafety.gov say
What to avoid
- Level E FDA:
Partially cooked seafood, such as shrimp and crab
(chart «Do not eat», Seafood row) FDA, Food Safety for Pregnant Women and Their Unborn Babies (booklet), accessed 2026-10-12 - Level E FDA:
Raw or undercooked fish or shellfish, or food containing raw or undercooked seafood (for example, sashimi) found in some sushi or ceviche.
(FDA list of foods for at-risk groups to avoid: pregnant women, children, older adults, people with weakened immune systems) FDA, Selecting and Serving Fresh and Frozen Seafood Safely, accessed 2026-10-12 - Level E FoodSafety.gov:
Raw seafood may contain parasites or germs, including Listeria, that can make pregnant women sick and could potentially harm their babies.
FoodSafety.gov, People at Risk: Pregnant Women, accessed 2026-10-12 - Level E ACOG:
You should also avoid raw fish and shellfish, including sushi. Raw fish has a higher risk of making you sick.
ACOG, Nutrition During Pregnancy (FAQ), accessed 2026-10-12 - Level E FDA:
Refrigerated smoked seafood and raw or undercooked seafood.
(«Make Safe Menu Choices», Higher Risk) FDA, Food Safety for Pregnant Women and Their Unborn Babies (booklet), accessed 2026-10-12
Amounts and limits
- Level E FDA:
Those who are pregnant or breastfeeding consume between 8 and 12 ounces per week of a variety of seafood from choices that are lower in mercury.
FDA, Food Safety for Pregnant Women and Their Unborn Babies (booklet), accessed 2026-10-12 - Level E FDA:
Goal: Women who are pregnant or breastfeeding should eat 2 to 3 servings and children should eat 2 servings of a variety of fish each week from the “Best Choices” list.
FDA, Selecting and Serving Fresh and Frozen Seafood Safely, accessed 2026-10-12 - Level E ACOG:
You should eat two or three servings of fish or shellfish per week before getting pregnant, while pregnant, and while breastfeeding.
ACOG, Nutrition During Pregnancy (FAQ), accessed 2026-10-12
Safer choices and when it is OK
- Level E FDA:
Fully cooked fish that is firm and flaky.
(«Make Safe Menu Choices», Lower Risk) FDA, Food Safety for Pregnant Women and Their Unborn Babies (booklet), accessed 2026-10-12 - Level E FDA:
They spoil rapidly after death, so only live crabs and lobsters should be selected and prepared.
FDA, Selecting and Serving Fresh and Frozen Seafood Safely, accessed 2026-10-12
How to cook or handle it
- Level E FoodSafety.gov:
All seafood dishes should be cooked to 145°F (63°C).
FoodSafety.gov, People at Risk: Pregnant Women, accessed 2026-10-12 - Level E FDA:
Most seafood should be cooked to an internal temperature of 145°F.
FDA, Selecting and Serving Fresh and Frozen Seafood Safely, accessed 2026-10-12 - Level E FoodSafety.gov:
Shrimp, lobster, crab, and scallops Cook until flesh is pearly or white, and opaque
(Safe Minimum Internal Temperature chart row (cells joined by a space)) FoodSafety.gov, Safe Minimum Internal Temperatures, accessed 2026-10-12 - Level E FDA:
Cook shrimp, lobster, and crab until they turn red and the flesh is the color of pearls.

Word-for-word quotes from official US sources. Level E means the position of an expert body. How we grade evidence.
Mercury: how much a week in pregnancy
| Kind | Mercury, mean ppm | Samples | FDA/EPA group | Servings a week |
|---|---|---|---|---|
| Lobster (spiny) | 0.093 | 13 | Best Choices | 2 to 3 servings of 4 oz a week |
| Lobster (northern or American) | 0.107 | 9 | Best Choices | 2 to 3 servings of 4 oz a week |
| Lobster | 0.166 | 71 | Best Choices | 2 to 3 servings of 4 oz a week |
Mercury: FDA testing 1990 to 2012. Groups and servings: FDA and EPA advice for people who are or may become pregnant and those who are breastfeeding. A serving is 4 oz (113 g) before cooking.
What a serving brings in pregnancy
| Nutrient | Per 4 oz (113 g) | % Daily Value |
|---|---|---|
| Protein | 21.5 g | 43% |
| Folate (DFE) | 12 mcg | 3% |
| Choline | 92 mg | 17% |
| Calcium | 109 mg | 8% |
| Vitamin B12 | 1.6 mcg | 68% |

What studies found
- Level C A scoping review of 46 studies on shellfish in pregnancy and early childhood found shellfish intake linked with higher contaminant biomarkers, mercury most of all. Nutr Res Rev, 2025
- Level C A review of 64 studies concludes shellfish carry mostly the less toxic organic arsenic yet remain a relevant dietary arsenic source, with contamination and geography as the main drivers of the level. Mar Pollut Bull, 2020
- Level E FDA and EPA list both shrimp and American and spiny lobster as Best Choices, so people who are pregnant or breastfeeding may eat 2 to 3 servings of 4 ounces a week of either. FDA and EPA, Advice about Eating Fish, page current as of 2024-03-05
Levels: A is a meta-analysis of trials, B a randomized trial, C an observational study, D lab or animal work, E an expert position. How we grade evidence.
In practice
Lobster ranged from 0.093 to 0.166 ppm of mercury in FDA testing, and FDA and EPA put American and spiny lobster in the Best Choices group (Level E). A 4 oz serving of cooked lobster has 21.5 g of protein and 109 mg of calcium.
Two things to watch. Cook it until the flesh is pearly and opaque. If you buy a whole fresh lobster, pick a live one, because FDA notes lobsters spoil quickly after death. A review of 46 studies found eating shellfish in pregnancy and early childhood tracked with higher contaminant markers, mercury most of all (Level C), so keep to the weekly amount.
That amount, 2 to 3 servings of 4 oz, is the total for all the fish and shellfish you eat in a week, not a separate allowance for lobster. FDA frames it as 8 to 12 oz a week of a variety of lower-mercury seafood.
