Overview
Tuna is a popular, protein-rich fish that many pregnant women enjoy, but it requires careful portion control due to mercury content. According to FDA and EPA guidelines, certain types of tuna can be part of a healthy pregnancy diet when consumed in moderation.
Safety Details
The primary concern with tuna during pregnancy is methylmercury, which can affect fetal brain development. Light canned tuna averages 0.12 ppm mercury, while albacore (white) tuna averages 0.32 ppm. The FDA recommends limiting albacore to 1 serving (4 oz) per week and allowing up to 2-3 servings of light tuna weekly. Risks include potential neurodevelopmental delays, supported by studies in Environmental Health Perspectives.
Key Risks
- Mercury accumulation in the fetus
- Possible listeria risk if not properly canned
- Lower omega-3 benefits compared to low-mercury fish like salmon
Trimester Guide
First trimester: Stick to light tuna only, max 8-12 oz per week total fish intake. Second trimester: Continue monitoring portions while focusing on variety. Third trimester: Maintain limits to support final brain growth; avoid raw tuna sushi entirely.

Alternatives/Tips
Choose canned light tuna in water, drain thoroughly, and pair with vegetables. Safer alternatives include salmon, sardines, and shrimp. Aim for 8-12 oz of low-mercury seafood weekly per ACOG recommendations.
When to Consult Your Doctor
Speak with your healthcare provider if you exceed recommended limits or experience symptoms like nausea after eating fish. Individual mercury testing may be advised for high consumers.
