According to FDA and ACOG guidelines, shellfish is a safe and nutrient-dense option during pregnancy when thoroughly cooked. Shellfish like shrimp, crab, and scallops are typically low in mercury, making them 'Best Choices' for fetal development. However, raw or undercooked shellfish, including oysters and clams, present significant risks of foodborne illnesses such as Vibrio, Salmonella, and Listeria monocytogenes. These pathogens can cause severe maternal illness and potential pregnancy complications. Guidelines specify that shellfish must reach an internal temperature of 145°F (63°C) to ensure safety. For mollusks like clams and mussels, shells must open during the cooking process; those that remain closed are discarded. Additionally, pregnant individuals are advised to monitor local water advisories for toxins like red tide, which are not eliminated by heat. Total seafood intake is recommended at 8 to 12 ounces per week.

Cooked Oysters

  • Ensure they are fully cooked until the shells open and the flesh is opaque.

Cooked Scallops

  • Safe when cooked thoroughly; the flesh should be firm and opaque.

Cooked Lobster

  • Ensure the meat is opaque and reaches an internal temperature of 145°F (63°C).

Cooked Clams

  • Cook until the shells open and the meat is firm.

Thoroughly Cooked Shrimp

  • Shrimp is classified as a 'Best Choice' by the FDA due to low mercury levels.
  • Safe when boiled, grilled, or sautéed to an internal temperature of 145°F until the flesh is opaque.

Fully Cooked Crab and Lobster

  • These options are safe when steamed or boiled until the meat turns pearly and opaque.
  • Commercial crab meat sold in cans or pouches is pasteurized and considered safe for consumption.

Cooked Scallops, Mussels, and Clams

  • Safe when cooked until shells open naturally or the flesh becomes firm and milky white.
  • Internal temperatures must reach 145°F to effectively neutralize potential parasites and bacteria.

Risks & Limits

Raw Shellfish

  • High risk of bacterial and viral infections; avoid during pregnancy.

Smoked Shellfish

  • Unless cooked to 165°F (74°C), they may harbor *Listeria*; avoid unless heated properly.

High-Mercury Fish

  • Some shellfish may contain higher mercury levels; limit intake and choose low-mercury options.

Raw or Undercooked Shellfish

  • Raw oysters, clams, and mussels carry high risks of Vibrio and Norovirus infections.
  • Undercooked preparations fail to reach the 145°F threshold required to kill harmful pathogens.

Refrigerated Smoked Seafood

  • Items labeled as 'nova-style,' 'lox,' or 'kippered' may contain Listeria unless cooked to 165°F in a dish.
  • Canned or shelf-stable smoked seafood is a safer alternative as it undergoes heat processing.
