Mussels (Cooked)

Sourced from ACOG/WHO/CDC guidelines • Updated June 2026
🟢 Generally Safe

Safety Status: Safe (Fully Cooked)

Fully cooked mussels are safe and highly nutritious for consumption during pregnancy.

As with other shellfish, raw mussels are unsafe because they are filter feeders and can concentrate viruses and bacteria. However, cooking them thoroughly to an internal temperature of 145°F (63°C) destroys these biological hazards, making them a safe prenatal choice.

Mussels are classified under the U.S. Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC) “Best Choices” list. They have low levels of methylmercury and are safe to consume in moderate amounts throughout gestation.

Nutritional Value of Mussels

Mussels are highly beneficial during pregnancy due to their dense nutrient profile:

  • Preventing Anemia: A single serving of cooked mussels provides a significant portion of your daily iron needs, which is essential to prevent maternal anemia and support the expanded red blood cell volume.
  • Nervous System Support: Mussels are rich in Vitamin B12, which is critical for the development of your baby’s brain, spinal cord, and nervous system, working alongside folate to prevent neural tube defects.
  • Omega-3 Fatty Acids: They provide DHA and EPA omega-3s, which contribute to fetal cognitive and visual development.
  • Protein and Zinc: Support cell growth, DNA synthesis, and immune system function.

Safe Cooking and Handling Guidelines

Follow these guidelines to prepare mussels safely at home:

  • Store Properly Before Cooking: Store live mussels in the refrigerator in a bowl covered with a damp cloth. Never seal them in an airtight bag or container, as they need to breathe.
  • Clean and Debeard: Wash mussels under cold water and scrape off any debris or “beards” (the fibrous threads they use to attach to rocks). Discard any mussels with cracked shells, or shells that are open and do not close when tapped.
  • Steam Until Open: Steam or boil mussels in a covered pot. Once the liquid boils and steam builds, cook for at least 5 minutes or until the shells open wide.
  • Discard Closed Mussels: Discard any mussels that do not open during the cooking process, as this indicates they were dead before cooking and are unsafe.
  • Weekly Intake: You can safely eat up to 8 to 12 ounces of low-mercury seafood per week, including cooked mussels.

Safe Alternatives

Fully cooked clams, scallops, or shrimp.

OB-GYN Clinical Tip

Steam mussels until their shells open wide, then discard any that remain closed. If eating out, verify that the mussels are freshly prepared and served steaming hot.

⚠️ Medical Safety Note Always wash fresh fruits and vegetables thoroughly, ensure meats and seafood are cooked to recommended internal temperatures, and verify that dairy products are fully pasteurized before consumption.

Pregnancy FAQs: Mussels (Cooked)

Q1: Can I eat mussels while pregnant?

Yes. Fully cooked mussels are safe to eat during pregnancy. They are low in mercury and provide excellent amounts of iron, protein, and vitamin B12.

Q2: Are raw mussels safe?

No. You must avoid raw or undercooked mussels due to the risk of foodborne infections from pathogens such as Norovirus, Vibrio, and Salmonella.
