What Happens If You Eat Sushi While Pregnant?

Eating sushi with raw or undercooked fish while pregnant can expose you and your baby to harmful bacteria, parasites, and mercury, potentially leading to miscarriage, stillbirth, or developmental problems. However, sushi made with fully cooked fish or vegetables is generally safe when prepared in a clean environment. The key is to avoid raw seafood and high-mercury fish, and to choose reputable restaurants that follow food safety standards. You can also explore Can You Eat Smoked Salmon While Pregnant?

Why Raw Sushi Is Risky During Pregnancy

Pregnancy changes your immune system, making you more susceptible to foodborne illnesses. Raw fish can harbor Listeria, Salmonella, and parasites like tapeworms. A Listeria infection during pregnancy can cross the placenta and cause miscarriage, stillbirth, or severe infection in the newborn. According to maternal-fetal medicine specialist Dr. Cara Dolin, babies born with listeriosis may suffer from paralysis, seizures, blindness, developmental delays, or organ damage. The bacteria specifically target the baby's blood system, affecting the brain and liver.

Parasites in raw fish, such as Anisakis, can also cause pregnancy complications. While freezing fish can kill some parasites, not all sushi-grade fish is frozen to the required temperatures, and cross-contamination can occur. The safest approach is to avoid raw fish entirely during pregnancy.

Mercury: A Hidden Danger in Some Fish

Mercury is a toxic heavy metal that accumulates in certain fish, especially large predatory species. Prenatal exposure to high levels of mercury can harm the developing fetal nervous system, leading to future developmental delays and motor skill issues. The FDA advises pregnant women to avoid high-mercury fish such as shark, swordfish, king mackerel, and tilefish. Even cooked versions of these fish should be avoided. Instead, choose low-mercury options like salmon, shrimp, catfish, and pollock, and limit intake to two to three 4-ounce servings per week.

Safe Sushi Options During Pregnancy

You don't have to give up sushi entirely. Many rolls are safe if they contain fully cooked ingredients or no fish at all. Safe choices include:

• California rolls made with cooked imitation crab (usually pasteurized).
• Vegetable rolls with cucumber, avocado, carrot, or other plant-based fillings.
• Cooked fish rolls using low-mercury seafood like cooked salmon, eel, or shrimp.
• Tamago sushi (sweet egg omelet) if the egg is thoroughly cooked.

Always ensure the sushi is prepared in a clean environment to avoid cross-contamination with raw fish. Ask the staff if they use separate cutting boards and utensils for raw and cooked items. Avoid buffet sushi or pre-packaged grocery store sushi that may have been sitting at room temperature.

What to Do If You Accidentally Ate Raw Sushi

If you've already eaten raw sushi, don't panic. The risk of infection is relatively low, especially if the sushi was from a reputable restaurant. Monitor yourself for symptoms of foodborne illness such as fever, vomiting, diarrhea, or flu-like symptoms. If you develop any symptoms, contact your healthcare provider immediately. They may recommend testing or treatment. In most cases, no immediate action is needed, but it's wise to inform your doctor at your next prenatal visit.

Cultural Perspectives: Do Japanese Women Eat Sushi While Pregnant?

In Japan, sushi is a traditional food, and many pregnant women continue to eat it, but they often choose cooked or low-mercury options. Japanese prenatal guidelines advise avoiding high-mercury fish like tuna and swordfish, but raw fish is not universally banned. However, food safety standards in Japan are stringent, and fish is often very fresh. In the U.S., the FDA and ACOG recommend avoiding raw fish during pregnancy due to the risk of Listeria and other pathogens. The difference in recommendations reflects varying risk assessments and food handling practices. Our breakdown of Can I Eat Fried Sushi While Pregnant? Safety Guide covers the related details.

Frequently Asked Questions

What are the odds of getting listeria from sushi?

Listeriosis is rare, but pregnant women are about 10 times more likely to get it than the general population. The exact odds depend on many factors, including the source and handling of the fish. Because the consequences can be severe, avoiding raw fish is the safest choice.

Can I eat sushi in my first trimester?

The first trimester is a critical period for fetal development, and the immune system is already adapting. It's best to avoid raw fish throughout pregnancy, including the first trimester. Cooked and vegetarian sushi are safe alternatives.

What if I ate sushi before I knew I was pregnant?

If you ate raw sushi before you knew you were pregnant, the risk is generally low. The most important thing is to avoid raw fish going forward and to mention it to your healthcare provider. They can offer reassurance and monitor your pregnancy as usual.

Bottom Line

Eating raw sushi while pregnant is not recommended due to the risks of bacteria, parasites, and mercury. However, you can still enjoy sushi made with cooked fish or vegetables. Always choose reputable restaurants, avoid high-mercury fish, and consult your healthcare provider for personalized advice.
