Pregnant women can safely enjoy low-mercury seafood like salmon, shrimp, and canned light tuna in moderation for essential nutrients.
Understanding Seafood Safety During Pregnancy
Pregnancy is a crucial time to pay close attention to diet, especially when it comes to seafood. Fish and shellfish provide valuable nutrients like omega-3 fatty acids, protein, and vitamins that support fetal brain development and maternal health. However, not all seafood is created equal during pregnancy. Some types contain high levels of mercury or pose risks of foodborne illnesses that can harm both mother and baby.
Knowing exactly what seafood you can eat during pregnancy helps you reap the benefits without unnecessary risk. The key is choosing options low in mercury and properly cooked to eliminate harmful bacteria or parasites.
Why Mercury Matters
Mercury is a naturally occurring element found in air, water, and soil. Industrial pollution increases mercury levels in bodies of water where fish live. Larger predatory fish tend to accumulate more mercury in their tissues over time. When consumed in excess during pregnancy, mercury can interfere with fetal brain and nervous system development.
The U.S. Food and Drug Administration (FDA) categorizes seafood based on mercury content:
- Low mercury: Safe to eat 2-3 servings per week
- Moderate mercury: Limit intake
- High mercury: Avoid completely during pregnancy
Sticking to low-mercury seafood ensures you get the benefits without risking harm from toxic buildup.
The Best Seafood Choices for Pregnant Women
Certain fish stand out as excellent choices for pregnancy due to their nutrient profile and low mercury content. These include:
Salmon
Salmon is a superstar when it comes to pregnancy nutrition. It’s packed with omega-3 fatty acids (DHA and EPA), which are essential for fetal brain and eye development. Wild-caught salmon tends to have lower contaminants than farmed varieties but both are generally safe if cooked thoroughly.
Shrimp
Shrimp offers a lean source of protein with very low mercury levels. It’s also rich in iodine, which supports thyroid function important for both mom and baby. Just be sure shrimp is cooked fully until opaque.
Canned Light Tuna
Canned light tuna has moderate mercury but is considered safe up to 2-3 servings per week by the FDA. Avoid albacore (white) tuna which contains higher mercury levels.
Sardines
These tiny fish are nutrient-dense powerhouses loaded with calcium, vitamin D, omega-3s, and protein—all critical during pregnancy. Sardines have very low mercury because they are small and short-lived.
Seafood To Avoid During Pregnancy
To protect your developing baby from potential toxins or infections, steer clear of these high-risk seafood items:
- Shark
- Swordfish
- King Mackerel
- Tilefish (from the Gulf of Mexico)
- Raw or undercooked shellfish: Oysters, clams, mussels (risk of bacterial contamination)
- Raw fish dishes: Sushi, sashimi (unless made with cooked seafood)
These choices often contain elevated mercury or harmful bacteria that could cause miscarriage or developmental problems.
Nutritional Benefits of Eating Seafood While Pregnant
Seafood isn’t just safe when chosen wisely—it’s downright beneficial during pregnancy. Here’s why:
- Omega-3 Fatty Acids: Crucial for brain growth and visual development in the fetus.
- High-Quality Protein: Supports tissue growth and repair for both mother and baby.
- Iodine: Helps regulate metabolism through thyroid hormone production.
- Zinc & Iron: Important for immune function and oxygen transport.
- Vitamin D & Calcium: Promote healthy bones and teeth formation.
Eating a variety of safe seafood ensures these nutrients complement other prenatal vitamins you may be taking.
The Importance of Proper Cooking Methods
Even the safest seafood can pose risks if not handled or cooked correctly during pregnancy. Bacteria like Listeria monocytogenes thrive in undercooked or raw seafood products and can cause serious infections leading to miscarriage or preterm labor.
Here are some cooking tips:
- Cook fish until it reaches an internal temperature of 145°F (63°C).
- Avoid raw preparations such as sushi or ceviche unless the fish has been previously frozen at temperatures that kill parasites.
- Avoid smoked seafood unless it’s cooked thoroughly before eating.
- Avoid cross-contamination by cleaning utensils and surfaces after handling raw fish.
Proper cooking destroys harmful pathogens while preserving nutrients.

Avoiding Common Pitfalls With Seafood During Pregnancy
Sometimes it’s not just about what you eat but how you source it that matters most:
- Select fresh seafood from reputable suppliers who follow proper storage protocols.
- Avoid fish caught from polluted waters or unknown sources.
- If eating out at restaurants, ask about sourcing practices and ensure dishes are fully cooked.
- If unsure about canned products’ safety or origin, opt for brands known for rigorous quality control.
- If allergic reactions have occurred before with shellfish or fish, consult your healthcare provider before consuming any type during pregnancy.

These precautions minimize exposure to contaminants beyond just mercury.
The Role of Portion Control With Seafood Consumption During Pregnancy
Even safe seafood should be enjoyed in moderation due to potential cumulative exposure risks from contaminants like PCBs (polychlorinated biphenyls) that may linger in some fish species.
The FDA recommends pregnant women consume about two to three servings (8-12 ounces) per week of low-mercury fish to maximize benefits while minimizing risks.
Balancing variety across different types also reduces chances of excessive intake from any one source.
Sustainable Choices That Align With Pregnancy Safety Guidelines
Choosing sustainable seafood isn’t just good for the planet—it often aligns with safer options for pregnant women since responsibly harvested species tend to have lower pollutant loads.
Look for certifications such as:
- Maine lobster certified by MSC (Marine Stewardship Council).
- Sustainably farmed salmon labeled by Aquaculture Stewardship Council (ASC).
- Shrimp harvested using eco-friendly methods verified by credible organizations.
