Seafood can be safe and beneficial during pregnancy when chosen wisely and consumed in moderation.
Understanding Seafood and Pregnancy Safety
Pregnancy demands careful attention to diet, as what a mother eats directly affects her baby’s development. Seafood is often praised for its rich nutrients, but the question remains: Is seafood bad for pregnancy? The answer isn’t a simple yes or no. Certain types of seafood provide essential nutrients like omega-3 fatty acids, protein, and vitamins that support fetal brain development. However, some seafood carries risks due to contaminants such as mercury or bacteria that can harm both mother and baby.
The key lies in selecting the right kinds of seafood and preparing them properly. Not all fish are created equal when it comes to pregnancy safety. Understanding which fish are low in mercury and how to avoid foodborne illnesses can help expecting mothers enjoy the benefits of seafood without unnecessary risks.
Why Seafood Is Often Recommended During Pregnancy
Seafood contains several nutrients vital for a healthy pregnancy:
- Omega-3 Fatty Acids (DHA and EPA): These fats play a crucial role in fetal brain and eye development.
- High-Quality Protein: Protein supports tissue growth for both mother and baby.
- Vitamins and Minerals: Fish provides vitamin D, iodine, selenium, and zinc—all important for pregnancy health.
For example, DHA (docosahexaenoic acid) is linked to improved cognitive function in babies after birth. Many prenatal vitamins include DHA because it’s so important during pregnancy. Seafood is one of the best natural sources of these fatty acids.
Additionally, fish protein is leaner than many meats, making it a heart-healthy choice that can help control gestational weight gain.
The Risks: Why Some Seafood Is Not Recommended
While seafood offers benefits, certain types pose risks during pregnancy due to:
Mercury Contamination
Mercury is a heavy metal found in varying levels in fish. High mercury exposure can damage the developing nervous system of the fetus. Large predatory fish tend to accumulate more mercury because they eat smaller fish that already contain it.
Examples of high-mercury fish to avoid include:
- Shark
- Swordfish
- King mackerel
- Tilefish
- Bigeye tuna
Consuming these can increase the risk of developmental delays or brain damage in babies.
Bacterial and Parasitic Infections
Raw or undercooked seafood carries risks from bacteria like Listeria monocytogenes or parasites such as tapeworms. Listeria infection during pregnancy can cause miscarriage, stillbirth, or severe illness in newborns.
Therefore, pregnant women should avoid sushi with raw fish, smoked seafood products unless cooked thoroughly, ceviche, or any uncooked shellfish.
Methylmercury vs. Other Contaminants
Methylmercury is the organic form found in fish that bioaccumulates up the food chain. Besides mercury, some fish may contain PCBs (polychlorinated biphenyls) or other toxins depending on their environment. These contaminants are linked to developmental problems but are less common with regulated fisheries.
Choosing wild-caught or certified sustainable seafood reduces exposure to such pollutants.
Nutrient Comparison: Common Seafood Choices During Pregnancy
Here’s a table comparing popular seafood options based on mercury content and nutrient benefits:
| Seafood Type | Mercury Level | Main Nutrients & Benefits |
|---|---|---|
| Salmon (wild-caught) | Low | High omega-3 DHA/EPA; vitamin D; protein; low contaminants |
| Tuna (canned light) | Moderate (low compared to albacore) | Good protein; moderate omega-3; affordable source |
| Shrimp | Low | Protein-rich; low fat; good source of selenium & iodine |
| Swordfish | High (avoid) | N/A – high mercury risk outweighs benefits during pregnancy |
| Canned Albacore Tuna | Higher than canned light tuna (limit intake) | Protein; omega-3s but consume cautiously due to mercury levels |
This table highlights why salmon and shrimp often top recommended lists—they offer great nutrition with minimal risk.
The Safe Amount: How Much Seafood Can Pregnant Women Eat?
Experts generally agree that pregnant women should aim for about two to three servings (8–12 ounces) of low-mercury seafood each week. This amount provides enough omega-3s without raising mercury levels dangerously.
The U.S. Food and Drug Administration (FDA) recommends:
- Avoid high-mercury fish entirely.
- Select lower-mercury choices such as salmon, shrimp, catfish, pollock, tilapia.
- If eating canned tuna: limit albacore tuna to no more than 6 ounces per week.
- Aim for variety rather than eating the same fish repeatedly.
- Avoid raw or undercooked seafood completely.
Pregnant women should also check local advisories if they consume locally caught freshwater fish since contamination levels vary by region.

Not all fish are safe during pregnancy. Educating yourself on which types are low in mercury and safe to eat helps minimize risks. Consulting healthcare providers can guide you in making the best seafood choices while pregnant.
The Importance of Proper Preparation and Cooking Methods
Cooking seafood thoroughly kills harmful bacteria and parasites that could otherwise cause infections dangerous during pregnancy.
Safe cooking tips include:
- Cook fish until it reaches an internal temperature of at least 145°F (63°C).
- Avoid raw dishes like sushi rolls containing raw fish or oysters on the half shell.
- DHA supports brain formation: It accumulates rapidly in fetal brain tissue during the last trimester when neurons develop connections rapidly.
- Select smaller species:Sardines, anchovies,and trout tend to have lower mercury levels due to shorter lifespans.
Avoid smoked seafood unless it’s cooked in dishes like casseroles.Avoid cross-contamination by cleaning utensils and surfaces after handling raw fish.Select fresh or properly frozen seafood from reputable sources.If eating canned seafood products like sardines or salmon, ensure they’re stored correctly before opening.If unsure about preparation safety at restaurants, choose cooked seafood options only.
