Can You Eat Shrimp While Pregnant? What Doctors Say About Seafood Safety
June 12, 2026·14 min read
You are at a restaurant, staring at the menu, and the shrimp looks incredible. Or you are mid-grocery shop, hand hovering over the frozen seafood section, genuinely unsure whether shrimp is on the safe list or the avoid list. Or maybe you already ate some and now you are searching to find out whether you need to worry.
Whatever brought you here — the answer is one you will be relieved to hear.
Yes, you can eat shrimp while pregnant. Not only is it safe, it is one of the better seafood choices you can make during pregnancy. Shrimp is low in mercury, high in protein, and provides nutrients that support your baby's development. The guidance from the FDA, ACOG, and the NHS is consistent and clear on this point.
But — as with most pregnancy nutrition questions — the full answer has some important detail attached to it. How it is cooked matters. How much you eat matters. And understanding what makes shrimp safe helps you apply the same thinking to other seafood questions that will inevitably come up over the next nine months.
This article covers everything: why shrimp is considered safe, how much you can eat, how it needs to be prepared, what to watch out for, and a clear guide to which other seafood is safe and which to avoid. By the end, you will have more than an answer to the shrimp question — you will have a framework for navigating seafood during pregnancy with confidence.
Why Mercury Is the Main Concern With Seafood in Pregnancy
To understand why shrimp is considered safe, it helps to first understand the primary risk that makes some seafood off-limits during pregnancy: mercury.
Mercury is a naturally occurring heavy metal that is present in the ocean and accumulates in fish tissue through a process called bioaccumulation. Large, long-lived predatory fish — the ones that eat many smaller fish over decades of life — accumulate the highest levels. When a pregnant woman eats high-mercury fish, mercury crosses the placenta and accumulates in fetal tissue, where it can damage the developing nervous system, brain, and sensory organs.
This is why the FDA and EPA maintain a "best choices," "good choices," and "fish to avoid" classification for seafood during pregnancy — based almost entirely on mercury content.
Shrimp falls squarely in the "best choices" category — one of the lowest-mercury seafood options available. This is because shrimp are small, short-lived, and low on the marine food chain. They simply do not live long enough or eat enough other marine life to accumulate significant mercury.
Average mercury level in shrimp: approximately 0.009 parts per million — among the very lowest of any seafood, well below the FDA's action level and significantly lower than species like swordfish (0.995 ppm) or shark (0.979 ppm).
What the Official Guidance Says
The guidance from major health and regulatory bodies is unambiguous about shrimp during pregnancy.
The FDA and EPA list shrimp as a "best choice" seafood for pregnant women, nursing mothers, and young children — the highest safety classification they offer. They recommend eating 2–3 servings (8–12 ounces) of best-choice seafood per week during pregnancy for the nutritional benefits.
The American College of Obstetricians and Gynecologists (ACOG) echoes this guidance, noting that low-mercury seafood including shrimp provides important nutrients for fetal development and should be included as part of a healthy pregnancy diet.
The NHS in the UK similarly lists prawns (the British term for what Americans call shrimp) as safe to eat during pregnancy when thoroughly cooked.
The consistent thread across all of these guidelines: shrimp is safe in appropriate quantities when fully cooked. Raw shrimp is a different matter, covered below.
How Much Shrimp Can You Eat While Pregnant?
The recommended amount of low-mercury seafood during pregnancy is 2–3 servings per week, totalling 8–12 ounces (225–340 grams). Shrimp counts toward this total.
To put that in perspective:
- A typical restaurant shrimp entrée is approximately 4–6 ounces
- A standard serving of shrimp as part of a meal is approximately 3–4 ounces
- A shrimp cocktail appetiser is typically 2–3 ounces
This means you could comfortably eat shrimp two to three times per week and remain well within the recommended limits. There is no compelling reason to restrict shrimp further than this guidance suggests — the mercury content is low enough that it does not drive meaningful accumulation even at regular consumption.
What you are not doing: accumulating dangerous mercury levels from shrimp. The mercury content is low enough that this simply is not a concern at normal eating amounts.
What you are doing: consuming a high-quality protein source, beneficial minerals, and nutrients that support your baby's development. That is a good trade.
How Shrimp Must Be Prepared During Pregnancy
This is where the detail matters. Safe shrimp during pregnancy means fully cooked shrimp — not raw, not undercooked.
Fully Cooked Shrimp: Safe and Recommended
Shrimp is safe during pregnancy when cooked to an internal temperature of 63°C/145°F until the flesh is firm, opaque, and pink throughout. Visual cues: raw shrimp is translucent and grey; properly cooked shrimp is pink, curled into a C-shape, and completely opaque with no translucent or grey patches remaining.
Safe preparations include:
- Grilled, sautéed, or pan-fried shrimp
- Boiled or steamed shrimp (including shrimp cocktail, when the shrimp is pre-cooked)
- Shrimp in pasta dishes, stir-fries, curries, and soups — as long as fully cooked through
- Frozen pre-cooked shrimp that has been defrosted and served cold (such as pre-cooked cocktail shrimp from the supermarket) — this is safe because it was cooked before freezing
- Shrimp tempura and other cooked preparations in Japanese restaurants
Raw Shrimp: Avoid During Pregnancy
Raw shrimp carries the same risks as other raw seafood during pregnancy — the potential for bacterial contamination (Listeria, Vibrio, Salmonella) and parasitic infection. Pregnancy suppresses the immune system, making these infections both more likely and more serious.
Avoid during pregnancy:
- Raw shrimp in any form
- Shrimp sashimi or raw shrimp preparations
- Any dish where you are unsure whether the shrimp is fully cooked
At restaurants, particularly sushi restaurants, it is always worth confirming whether a shrimp preparation is cooked. Most sushi restaurant shrimp (ebi) is actually pre-cooked — but it is reasonable to ask.
A Note on Pre-Cooked Frozen Shrimp
Pre-cooked frozen shrimp — the kind sold in bags at the supermarket, labelled "cooked" — is safe to eat during pregnancy after proper defrosting. It was fully cooked before freezing. Defrost in the refrigerator or under cold running water and use promptly. Do not refreeze after defrosting.
The Nutritional Benefits of Eating Shrimp During Pregnancy
Shrimp is not merely "safe" — it is genuinely nutritious, and understanding what it provides makes the case for including it regularly rather than just occasionally.
Protein
Shrimp is an excellent source of lean protein — approximately 20g of protein per 100g serving — with minimal saturated fat. Protein needs increase significantly during pregnancy (to approximately 75–100g per day), and shrimp provides a lean, complete protein source that contributes meaningfully to that total.
Iodine
Shrimp is one of the better dietary sources of iodine — a nutrient that is critical for fetal thyroid hormone production and brain development, particularly in the first trimester, and one that is commonly insufficient in pregnancy diets. A 100g serving of shrimp provides approximately 35–40mcg of iodine, contributing to the 220mcg daily requirement during pregnancy.
Selenium
Shrimp is rich in selenium — approximately 38mcg per 100g — an antioxidant mineral that supports thyroid function, immune health, and cellular protection. Selenium requirements increase modestly during pregnancy.
Zinc
Zinc is essential for immune function, cell division, and fetal development. Shrimp provides approximately 1.1mg of zinc per 100g — a meaningful contribution to the 11–12mg daily requirement during pregnancy.
Omega-3 Fatty Acids
While shrimp is not as rich in omega-3s as oily fish like salmon or sardines, it does contain a small but meaningful amount of DHA and EPA — the omega-3 fatty acids critical for fetal brain and eye development. Including shrimp as part of a varied seafood intake contributes to overall omega-3 intake alongside richer sources.
B Vitamins
Shrimp provides B12, niacin (B3), and B6 — all of which support energy metabolism, neurological development, and red blood cell production during pregnancy.
What About Other Shrimp Concerns?
Cholesterol
Shrimp is relatively high in dietary cholesterol — approximately 189mg per 100g. Dietary cholesterol was once a significant nutritional concern, but current evidence suggests it has far less impact on blood cholesterol levels than previously thought for most people. The current consensus does not restrict shrimp based on cholesterol content in healthy pregnancies. If you have a specific lipid or cardiovascular concern, discuss it with your provider.
Shellfish Allergies
If you have a shellfish allergy, pregnancy does not change that — avoid shrimp entirely. Shellfish allergies can be serious and can intensify during pregnancy. If you develop any new allergic symptoms after eating shrimp during pregnancy — hives, itching, swelling, breathing difficulty — seek medical attention promptly.
Sourcing and Quality
Wild-caught shrimp is generally preferred over some farmed varieties for sustainability and quality reasons, though both are safe during pregnancy from a mercury and food safety perspective. Choose reputable sources, ensure shrimp smells fresh (not strongly fishy or ammonia-like), and store properly — refrigerated for 1–2 days or frozen for longer storage.
A Complete Guide to Seafood Safety During Pregnancy
Since seafood safety questions tend to cluster together — once you are asking about shrimp, you are often wondering about salmon, tuna, sushi, and everything else — here is a comprehensive reference guide.
Best Choices: Eat 2–3 Servings Per Week
These are the lowest-mercury, most beneficial seafood choices for pregnancy. Shrimp belongs in this group.
- Shrimp — lowest mercury, high protein, excellent iodine source
- Salmon — excellent DHA source, low mercury, high protein and vitamin D
- Sardines — DHA, calcium (with bones), iron, and very low mercury
- Pollock — very low mercury, lean protein
- Tilapia — very low mercury, mild flavour, widely available
- Cod — low mercury, lean protein, iodine
- Catfish — low mercury
- Canned light tuna — low mercury; up to 2–3 servings per week
- Herring — excellent omega-3 source, low mercury
- Trout — low mercury, good DHA content
- Anchovies — low mercury, concentrated omega-3s
Good Choices: Eat No More Than 1 Serving Per Week
- Albacore (white) canned tuna — higher mercury than light tuna; limit to one serving
- Mahi-mahi — moderate mercury
- Snapper — moderate mercury
- Halibut — moderate mercury
- Carp — moderate mercury
- Grouper — moderate mercury
Avoid During Pregnancy: High Mercury
These fish have mercury levels high enough to pose genuine risk to fetal neurological development:
- Shark
- Swordfish
- King mackerel
- Tilefish (Gulf of Mexico)
- Bigeye tuna (common in sushi restaurants)
- Marlin
- Orange roughy
Raw Seafood: Avoid Regardless of Mercury Level
- Raw sushi and sashimi (any fish)
- Raw oysters, clams, and mussels
- Ceviche (acid does not kill all pathogens)
- Refrigerated smoked seafood unless cooked into a hot dish
Eating Shrimp at Restaurants During Pregnancy
Eating out while pregnant raises the same questions for shrimp as it does at home — is it fully cooked? Where did it come from? Here is practical guidance for common restaurant scenarios.
American restaurants and seafood restaurants: Grilled, sautéed, fried, or baked shrimp in a hot dish is almost always fully cooked. Shrimp cocktail uses pre-cooked shrimp and is safe.
Sushi restaurants: Most shrimp in sushi is ebi — a pre-cooked, butterflied shrimp that is safe during pregnancy. Confirm with your server. Cooked shrimp rolls (California roll variations, tempura shrimp rolls) are safe. Avoid any raw preparations.
Mexican restaurants: Cooked shrimp in tacos, burritos, and fajitas is safe. Avoid ceviche, which is raw shrimp marinated in citrus — the acid does not fully kill pathogens.
Thai and Asian restaurants: Shrimp in stir-fries, curries, pad thai, and similar dishes is cooked through and safe. Confirm with staff if you have any uncertainty.
Buffets: Exercise caution with buffet seafood — shrimp that has been sitting at room temperature for extended periods poses a food safety risk regardless of how it was originally cooked. Choose freshly prepared options when possible.
Frequently Asked Questions
Can I eat shrimp in the first trimester?
Yes — shrimp is safe throughout pregnancy, including the first trimester. The key requirements are the same at any stage: fully cooked and within the 8–12 ounce per week seafood guideline. The first trimester is when many women struggle with food aversions and nausea, but for those who can tolerate it, shrimp is a nutritious protein source that is easy to prepare in many ways.
Is frozen shrimp safe during pregnancy?
Yes. Pre-cooked frozen shrimp — labelled "cooked" on the packaging — is safe to eat after proper defrosting, as it was fully cooked before freezing. Raw frozen shrimp requires thorough cooking before eating during pregnancy, just as fresh raw shrimp does. Do not refreeze defrosted shrimp.
Can I eat shrimp cocktail while pregnant?
Yes — shrimp cocktail uses pre-cooked shrimp and is safe during pregnancy. This applies whether made at home with pre-cooked cocktail shrimp or ordered at a restaurant. The shrimp in shrimp cocktail is cooked before serving.
Is shrimp high in mercury?
No — shrimp is one of the lowest-mercury seafood options available, with an average mercury level of approximately 0.009 parts per million. It is listed in the FDA's "best choices" category for pregnant women. Mercury is not a concern with shrimp at recommended serving amounts.
Can I eat prawns while pregnant? (UK readers)
Yes — prawns (the British term for shrimp) are safe during pregnancy when fully cooked. The NHS lists prawns as safe to eat during pregnancy. The same guidance applies: fully cooked, within 2–3 servings of low-mercury seafood per week.
What if I ate raw shrimp before I knew I was pregnant?
Try not to panic. A single exposure to raw shrimp carries a probabilistic risk rather than a certainty of harm. Most people who eat contaminated seafood experience mild gastrointestinal symptoms, not serious illness. However, if you develop symptoms — fever, vomiting, significant abdominal pain — contact your care provider. A single past exposure is not a reason for ongoing anxiety; mention it at your next prenatal appointment if you have concerns.
How should I cook shrimp during pregnancy?
Cook shrimp until it is completely pink and opaque throughout, with no translucent or grey patches — typically 2–3 minutes per side when sautéed or grilled. The internal temperature should reach 63°C/145°F. Properly cooked shrimp curls into a loose C-shape; overcooked shrimp curls tightly into an O-shape. Aim for the C.
Can I eat garlic butter shrimp while pregnant?
Yes — as long as the shrimp is fully cooked through, the preparation method does not affect safety. Garlic butter shrimp, shrimp scampi, grilled shrimp with herbs, coconut shrimp, shrimp stir-fry — all are safe when the shrimp is completely cooked.
Conclusion: Enjoy Your Shrimp
The seafood section of pregnancy nutrition guidance contains genuine complexity — high-mercury fish to avoid, raw preparations to skip, quantity limits to observe. But shrimp is one of the clearest, least complicated answers in that whole conversation.
It is safe. It is nutritious. The guidance from every major health body says to eat it. The only real requirements are that it is fully cooked and eaten in sensible amounts as part of a varied diet.
So order the shrimp. Make the prawn curry. Add them to the pasta. Build them into your seafood rotation alongside salmon, sardines, and cod — and know that you are eating well for both yourself and your baby.
There are enough things to navigate carefully during pregnancy. Shrimp does not have to be one of them.
Not everything in pregnancy is complicated. Fully cooked shrimp, eaten regularly, is one of the easier and better choices you can make for yourself and your baby. Enjoy it.
