What Guidelines Say

Consuming raw oysters during pregnancy poses significant risks due to potential bacterial and parasitic infections.

Read more details

Major health organizations, including the FDA and ACOG, categorize raw oysters as a high-risk food during pregnancy. The primary concern is the presence of harmful bacteria and viruses, most notably Vibrio vulnificus, Listeria monocytogenes, and Norovirus. Unlike many other foodborne illnesses, Vibrio infections can be particularly severe or even fatal for individuals with suppressed immune systems, including pregnant women. These pathogens are naturally found in coastal waters where oysters grow and cannot be seen, smelled, or tasted. While lemon juice or hot sauce are common accompaniments, they do not eliminate these bacteria. Only thorough cooking to an internal temperature of 145°F effectively kills these pathogens. Consequently, guidelines recommend strictly avoiding raw or undercooked shellfish to prevent maternal illness and potential fetal complications.

Safer Choices

Fully Cooked Oysters

  • Cooking oysters to an internal temperature of 145°F (63°C) effectively eliminates harmful pathogens.
  • Boiling, frying, or baking oysters until they reach an internal temperature of 145°F kills harmful pathogens.
  • Oysters are cooked until the flesh is firm and the edges curl.

Canned Oysters

  • Commercially canned oysters are typically cooked during processing, making them a safe option.

Other Low-Mercury Seafood

  • Options like salmon, shrimp, and catfish are considered safe when fully cooked and consumed in moderation.

Canned or bottled oysters

  • Commercially processed and shelf-stable canned oysters are heat-treated during canning, making them safe for consumption.
  • These are suitable for use in stews or dressings.

Fried oyster preparations

  • Oysters that are battered and deep-fried until the centers are hot and firm meet safety standards.
  • This preparation method effectively mitigates the risk of bacterial contamination.

Oyster stew or chowder

  • Oysters simmered in liquid until the internal temperature reaches 145°F are considered safe.
  • The heat from the liquid ensures the destruction of Vibrio and other viruses.

Risks & Limits

Raw Oysters

  • Due to the risk of bacterial and parasitic infections, raw oysters should be avoided during pregnancy.

Smoked Oysters

  • Unless heated to 165°F (74°C), smoked oysters may pose a risk of Listeria infection and should be avoided.

High-Mercury Fish

  • Fish such as king mackerel, shark, and swordfish contain high mercury levels and should be avoided.

Raw oysters on the half shell

  • These carry the highest risk of Vibrio vulnificus and Norovirus contamination.
  • Freezing or adding acidic condiments does not make raw oysters safe for pregnant women.

Lightly steamed oysters

  • If the internal temperature remains below 145°F, bacteria may survive the cooking process.
  • Shells that do not open during steaming indicate the oyster may not have reached a safe temperature.

Raw oyster shooters

  • These preparations involve raw shellfish and do not undergo any heat treatment to kill pathogens.
  • Alcohol or cocktail sauce used in shooters does not provide protection against foodborne illness.
