Overview
Shrimp is a popular seafood choice that can be part of a healthy pregnancy diet when prepared correctly. According to the FDA, shrimp is classified as a low-mercury seafood, making it a safer option compared to high-mercury fish like swordfish. It provides lean protein, omega-3 fatty acids, and essential nutrients such as selenium and vitamin B12 that support fetal development. ACOG recommends that pregnant women consume 8-12 ounces of low-mercury seafood weekly, and shrimp fits well within these guidelines.
Safety Details
The primary risks associated with shrimp during pregnancy include bacterial contamination like listeria or salmonella if the shrimp is raw or undercooked. Toxoplasmosis is less common with shrimp but possible with any undercooked seafood. Mercury levels in shrimp are minimal, averaging less than 0.01 mg per serving, well below the FDA's 0.1 mcg/g safety threshold. Studies in the Journal of Nutrition show that moderate seafood intake correlates with improved cognitive outcomes in children without increased mercury exposure.
Safe Preparation Methods
- Cook shrimp to an internal temperature of 145°F (63°C) until it turns opaque and firm.
- Avoid raw shrimp in sushi, ceviche, or salads.
- Opt for fresh or frozen shrimp from reputable sources and store properly to prevent cross-contamination.
Portion limits: Up to 12 ounces (340 grams) per week of cooked shrimp, spread across 2-3 meals. This aligns with EPA and FDA joint advice for low-mercury options.

Trimester Guide
First Trimester: Shrimp can help meet increased protein needs (75-100g daily) while managing nausea; focus on small, frequent servings of well-cooked shrimp.
Second Trimester: Continue moderate intake to support fetal brain development via DHA from shrimp; no trimester-specific restrictions apply beyond general cooking rules.
Third Trimester: Maintain 8-12 oz weekly limit to avoid any potential digestive discomfort; shrimp remains beneficial for maternal energy levels.
Alternatives/Tips
If avoiding shrimp, consider other low-mercury alternatives like salmon (up to 12 oz/week), cod, or canned light tuna. Tips include pairing shrimp with vegetables for balanced meals and choosing wild-caught or sustainably farmed varieties. Always check local advisories for any regional contaminants.
When to Consult Your Doctor
Speak with your healthcare provider if you have a shellfish allergy, experience symptoms like vomiting after eating seafood, or live in an area with specific water quality concerns. Individual dietary needs may vary based on prenatal bloodwork.
