Consuming masago accidentally during pregnancy is generally low risk, but caution is advised due to potential bacteria and mercury concerns.
Understanding Masago and Its Composition
Masago, often seen as the tiny orange beads topping sushi rolls, is the roe (eggs) of the capelin fish. It’s prized for its crunchy texture and mild flavor, frequently used as a garnish in Japanese cuisine. Unlike other fish eggs such as tobiko or ikura, masago is smaller and less oily, making it a popular choice in various dishes.
The nutritional profile of masago includes proteins, omega-3 fatty acids, vitamins such as B12, and minerals like selenium. However, because it is a raw seafood product, it carries some inherent risks when consumed by pregnant women. The primary concerns involve bacterial contamination and mercury content.
Pregnancy demands extra vigilance regarding diet because the immune system is naturally suppressed to accommodate the fetus. This suppression makes pregnant women more vulnerable to foodborne illnesses caused by bacteria like Listeria monocytogenes or parasites that can be present in raw or undercooked seafood.
The Risks of Eating Masago During Pregnancy
Eating raw fish products like masago during pregnancy introduces two main concerns: foodborne illness and mercury exposure.
Bacterial Contamination
Raw fish eggs can harbor harmful bacteria such as Listeria. Listeriosis during pregnancy poses serious risks including miscarriage, premature birth, or severe infection in newborns. Although masago undergoes some processing—often pasteurization or freezing—cross-contamination or improper handling can still lead to bacterial presence.
Symptoms of listeriosis range from mild flu-like signs to severe complications requiring hospitalization. Pregnant women are about 10 times more likely to get listeriosis than others due to their altered immune response.
Mercury Levels in Masago
Mercury accumulates in aquatic food chains and can affect fetal brain development when consumed in high amounts by pregnant women. Fortunately, capelin—the source of masago—is a small fish with relatively low mercury levels compared to larger predatory fish like swordfish or tuna.
Still, consistent consumption of any seafood containing mercury should be moderated during pregnancy to avoid cumulative effects.
Other Parasites and Allergens
Raw seafood may also carry parasites such as Anisakis worms that can cause digestive distress or allergic reactions. Though freezing kills most parasites, there’s no absolute guarantee unless proper food safety protocols are followed. Allergic reactions to fish roe are another consideration; if you have known seafood allergies, consuming masago could trigger symptoms.
What Happens If You Accidentally Ate Masago While Pregnant?
First off: don’t panic. Accidentally eating masago once during pregnancy is unlikely to cause serious harm if the product was fresh and handled correctly.
The body’s immune system may handle minor bacterial exposure without symptoms. However, vigilance is key. Watch for any signs of food poisoning within 24-48 hours after consumption:
- Fever
- Nausea or vomiting
- Diarrhea
- Muscle aches
- Headache
If you experience these symptoms—especially fever—contact your healthcare provider immediately for assessment and possibly testing for listeriosis.
In the absence of symptoms, no specific treatment or intervention is required after a single accidental ingestion of masago.
How Safe Is Masago Compared to Other Seafood in Pregnancy?
Seafood safety during pregnancy varies widely depending on species, preparation method, and source quality. Here’s a quick comparison between masago and other common seafood options:
| Seafood Type | Mercury Level | Pregnancy Safety Rating |
|---|---|---|
| Masago (Capelin Roe) | Low | Cautiously Safe* |
| Tuna (especially albacore) | Moderate-High | Avoid Excess Consumption |
| Salmon (cooked) | Low | Safe When Cooked Properly |
| Swordfish & King Mackerel | High | Avoid Completely During Pregnancy |
| Sushi with Raw Fish (general) | Varies* | Avoid Due To Bacterial Risk |
*Masago’s safety depends largely on its handling and whether it has been frozen or pasteurized before consumption.
Pregnant women are encouraged to consume cooked seafood that’s low in mercury rather than raw varieties or roe products unless verified safe.

What are the risks of eating masago while pregnant?
The main risks include exposure to bacteria such as Listeria and low levels of mercury. Listeriosis can cause serious pregnancy complications, but masago often undergoes processing to reduce this risk. Mercury levels in masago are relatively low compared to larger fish.
Can eating masago while pregnant harm my baby’s development?
Mercury in seafood can affect fetal brain development if consumed in high amounts. Since masago comes from capelin, a small fish with low mercury, occasional accidental consumption is unlikely to cause harm. Still, moderation is important throughout pregnancy.
What should I do if I ate masago while pregnant and feel unwell?
If you develop symptoms like fever, muscle aches, or digestive issues after eating masago, contact your healthcare provider immediately. These could be signs of listeriosis or another infection requiring medical attention during pregnancy.
How can I avoid accidentally eating masago while pregnant?
To avoid accidental consumption, inform restaurant staff about your pregnancy and ask about ingredients in sushi or seafood dishes. Reading menus carefully and choosing fully cooked options can help minimize the risk of exposure to raw fish eggs like masago.

If you decide to include masago in your diet during pregnancy despite general recommendations against raw seafood, follow strict safety guidelines:
- Purchase from reputable sources: Choose suppliers who follow rigorous hygiene standards.
- Check for pasteurization: Some brands freeze or heat-treat their masago to reduce bacterial risks.
- Avoid cross-contamination: Use clean utensils and surfaces separate from raw meats.
- Store properly: Keep it refrigerated at temperatures below 40°F (4°C) until use.
- Avoid homemade sushi with raw eggs: Homemade preparations often lack proper freezing steps.
- If unsure about safety: Opt for cooked seafood alternatives instead.
- DHA Omega-3 fatty acids: Essential for fetal brain and eye development.
