Can You Eat Fish While Pregnant?

Is fish safe to eat during pregnancy?

Yes, properly cooked low-mercury fish is safe and beneficial during pregnancy. The FDA and EPA jointly recommend pregnant women eat 8-12 ounces (2-3 servings) of low-mercury fish per week. The DHA and EPA omega-3 fatty acids in fish are crucial for fetal brain and eye development, with studies linking maternal seafood consumption to better cognitive outcomes in children. The vast majority of fish are safe during pregnancy when cooked properly; only specific high-mercury varieties should be avoided. The FDA categorizes fish into three tiers based on mercury content: 'best choices' (eat 2-3 times per week), 'good choices' (eat once per week), and 'choices to avoid' (skip during pregnancy). Following these guidelines provides nutritional benefits while minimizing mercury exposure.

Which fish should you avoid during pregnancy?

The FDA lists seven fish in the 'choices to avoid' category due to high mercury content: shark, swordfish, king mackerel, marlin, orange roughy, tilefish from the Gulf of Mexico, and bigeye tuna. These predator fish are larger, longer-lived, and accumulate more mercury through their food chain. Mercury can cross the placenta and affect fetal nervous system development, with cumulative exposure being the main concern. Local advisories may add other fish to avoid based on regional water contamination; pregnant women should check their state's fish consumption advisories for recreationally caught fish. Beyond mercury, avoid raw fish in any form: sushi, sashimi, ceviche, poke bowls, raw oysters, and refrigerated smoked fish. These can carry Listeria, parasites, or bacteria more dangerous during pregnancy.

What are the best fish choices during pregnancy?

The FDA's 'best choices' (eat 2-3 times per week): salmon, anchovies, cod, catfish, flounder, haddock, hake, herring, mullet, Pacific chub mackerel, perch, pollock, sardine, shad, smelt, sole, tilapia, trout (freshwater), canned light tuna, whitefish, and whiting. Salmon is particularly recommended for its high omega-3 content (about 1.5g per 3 oz serving). Sardines and anchovies are excellent sources of omega-3s and have very low mercury. The 'good choices' (eat once per week): albacore tuna, yellowfin tuna, halibut, mahi mahi, snapper, grouper, monkfish, and rockfish. These have moderate mercury but still provide nutritional benefits. For variety, rotate among 'best choices' fish; this provides different nutrient profiles and reduces concentration of any single contaminant.

How should you prepare fish safely during pregnancy?

Cook fish to 145°F internal temperature (flesh should be opaque and flake easily with a fork at the thickest point). For thicker cuts, use a food thermometer. Baking, grilling, broiling, and poaching all work; the cooking method matters less than reaching safe temperature. Avoid raw preparations entirely during pregnancy: sushi, sashimi, ceviche, poke. Cooked sushi (California rolls with cooked imitation crab, tempura shrimp rolls, BBQ eel rolls) is generally safe if from a reputable restaurant. Store fresh fish at 40°F or below and use within 1-2 days. Thaw frozen fish in the refrigerator. Wash hands and surfaces after handling raw fish to prevent cross-contamination. When eating out, request fully cooked fish and ask about preparation methods if uncertain about safety.
