Yes, you can eat sushi while nursing, but not all sushi is the same. The main concern is not the sushi itself — it is the type of fish and whether it is raw or cooked. Most nursing mothers can safely eat cooked sushi and low-mercury raw fish in moderation. High-mercury fish and raw fish linked to foodborne illness are the ones to limit or avoid.
This guide breaks down what is actually risky, what is not, and how to make safe choices without giving up sushi entirely.
Can You Eat Sushi While Nursing?
In most cases, yes. Neither raw fish nor cooked sushi passes into breast milk in a way that would harm a nursing baby. The real risks are two: foodborne illness in the mother, and mercury exposure from certain fish.
Mercury is the bigger concern for breastfeeding. Mercury from fish can pass into breast milk, and infants are more vulnerable to its effects on the developing nervous system. That is why the type and amount of fish matter more than whether it is raw or cooked.
Foodborne illness is a concern for you, not directly for your baby through milk. If you get sick from raw fish, you may feel terrible and struggle to care for your baby. But the bacteria or parasites that cause the illness do not typically transfer through breast milk.
The practical takeaway: choose low-mercury fish, keep raw fish to a minimum, and avoid high-mercury varieties entirely.
Which Fish Are Safe and Which Should You Avoid?
Mercury content is the deciding factor. Fish absorb mercury from the environment, and larger, longer-lived predator fish accumulate the most. The US Food and Drug Administration and Environmental Protection Agency publish guidance on mercury in fish for people who are pregnant or breastfeeding.
Here is how common sushi fish stack up:
| Fish | Mercury Level | Sushi Guidance |
|---|---|---|
| Salmon | Low | Safe, raw or cooked |
| Shrimp | Low | Safe, cooked |
| Tuna (canned light) | Low | Safe, limit to 2-3 servings per week |
| Tuna (albacore/white) | Moderate | Limit to 1 serving per week |
| Yellowfin tuna | Moderate | Limit |
| Bluefin tuna | High | Avoid |
| Swordfish | High | Avoid |
| Shark | High | Avoid |
| King mackerel | High | Avoid |
| Tilefish | High | Avoid |
| Eel (unagi) | Moderate | Usually cooked, limit |
| Octopus (tako) | Low | Safe, cooked |
| Squid (ika) | Low | Safe, cooked |
These mercury categories come from FDA and EPA guidance for people who are pregnant or breastfeeding. The same limits apply while nursing.
One clarification worth knowing: canned light tuna is usually skipjack, which is smaller and lower in mercury than albacore. That is why the two are treated differently in the guidance.
What About Raw Fish and Foodborne Illness?
Raw fish can carry parasites and bacteria. The most common concerns in sushi are Anisakis parasites, Listeria, Vibrio, and Salmonella. These can make you sick, sometimes seriously.
Sushi-grade fish is not a regulated term. It generally means the fish was frozen to a temperature that kills parasites, or was handled to reduce bacterial risk. Freezing at the right temperature and duration kills parasites but does not eliminate all bacteria.
Listeria is a particular concern during pregnancy because it can cross the placenta. While nursing, the risk to your baby through milk is not the same. The main risk is to you. Still, many clinicians suggest continuing to avoid high-risk raw foods while breastfeeding, partly out of caution and partly because a serious illness in a new mother is hard on the whole household.
If you choose to eat raw fish, buy from a reputable restaurant or supplier that follows safe handling practices. Avoid gas station sushi, buffets, and anything that has been sitting out.
How Much Fish Should You Eat While Nursing?
The FDA and EPA recommend that people who are pregnant or breastfeeding eat 2 to 3 servings of low-mercury fish per week. A serving is about 4 ounces. That is roughly the size of your palm.
This recommendation exists because fish is a good source of omega-3 fatty acids, protein, and other nutrients that support both mother and baby. The goal is to get the benefits while keeping mercury low.
If you eat sushi, count each piece of fish toward your weekly total. A typical sushi roll contains about 1 to 2 ounces of fish. A sashimi plate may have 3 to 4 ounces. Keep a rough tally so you stay within the recommended range.
If you are unsure how much mercury is in a particular fish, choose salmon, shrimp, or canned light tuna instead. These are consistently low.
Does Mercury Pass Into Breast Milk?
Yes. Mercury from fish is absorbed into your bloodstream and can pass into breast milk. The amount depends on how much mercury is in the fish you ate and how recently you ate it.
Methylmercury, the form found in fish, is a neurotoxin. Infants are more susceptible because their brains and nervous systems are still developing. That is why the guidance focuses on keeping mercury intake low rather than eliminating fish entirely.
The good news is that low-mercury fish like salmon do not pose a meaningful mercury risk. The concern is specifically with high-mercury fish and with eating large amounts of moderate-mercury fish.
If you accidentally ate a high-mercury fish once, do not panic. One exposure is unlikely to cause harm. The goal is to avoid repeated or high-dose exposure over time.
What Are Safe Alternatives to Raw Sushi?
If you want to avoid raw fish entirely, you have plenty of options. Cooked sushi is widely available and carries no parasite risk.
- Cooked shrimp (ebi)
- Cooked crab (kani)
- Cooked eel (unagi)
- Cooked octopus (tako)
- Cooked squid (ika)
- Tempura rolls
- California rolls (imitation crab is cooked)
- Avocado rolls
- Cucumber rolls
- Cooked salmon or tuna rolls
Vegetarian sushi is another safe choice. It avoids both mercury and parasite concerns. Just watch for cross-contamination if the restaurant uses the same prep area for raw fish.
If you are craving raw fish, salmon sashimi from a reputable source is generally considered a lower-risk choice because salmon is low in mercury. Still, the parasite and bacteria risk exists, so make your own decision based on your comfort level and your health history.
What Do Health Organizations Say?
The FDA and EPA both publish guidance for people who are pregnant or breastfeeding. Their advice is consistent: eat 2 to 3 servings of low-mercury fish per week, avoid high-mercury fish, and follow safe food handling practices.
The Centers for Disease Control and Prevention also advises people who are pregnant to avoid raw fish and raw shellfish. While nursing, the CDC does not specifically prohibit raw fish, but many clinicians extend the pregnancy guidance into the breastfeeding period as a precaution.
The American College of Obstetricians and Gynecologists recommends that people who are pregnant or breastfeeding limit fish to 2 to 3 servings per week of low-mercury varieties. The organization does not single out sushi as uniquely dangerous, but it does emphasize avoiding high-mercury fish.
Different organizations phrase their guidance differently, but the core message is the same. Low-mercury fish is good. High-mercury fish is not. Raw fish carries a food safety risk that is mostly about you, not your milk.
Frequently Asked Questions
Can you eat sushi while nursing?

Does mercury from sushi pass into breast milk?
Yes, mercury from fish can pass into breast milk. The amount depends on the type and amount of fish you eat, which is why low-mercury choices matter.
Is raw sushi safe while breastfeeding?
Raw sushi carries a risk of parasites and bacteria that can make you sick. It does not pass those germs through breast milk, but many clinicians suggest avoiding raw fish as a precaution.
How much sushi can you eat while breastfeeding?
Follow the FDA and EPA guidance of 2 to 3 servings of low-mercury fish per week. A serving is about 4 ounces, and each sushi piece counts toward that total.
