Can I eat bean sprouts while pregnant?

The verdict

Raw bean sprouts, alfalfa sprouts, mung bean sprouts, radish sprouts, clover sprouts and onion sprouts are on the avoid list in the United States and Australia, and are not mentioned at all in UK pregnancy advice. Cooked thoroughly, they are an ordinary vegetable everywhere.

The FDA is direct: avoid eating raw sprouts of any kind, including alfalfa, clover, radish and mung bean. Food Standards Australia New Zealand lists raw seed sprouts among the higher-risk foods that pregnant people should not eat, in the same group as pre-prepared salads, refrigerated pâté and soft serve ice cream.

The NHS foods to avoid page does not name sprouts in any form. Its fruit and vegetable section says most fruits and vegetables are safe if washed thoroughly, and singles out only enoki mushrooms and pre-cut fruit for special treatment. That silence is the genuine disagreement on this page, and it is worth understanding why washing is exactly the wrong answer here.

Why washing does not work on sprouts

Most produce advice is about surface contamination: soil, handling, water. Rinse it and you remove most of the problem. Sprouts break that logic.

The FDA sets out the mechanism plainly. Bacteria can get into sprout seeds through cracks in the shell before the sprouts are grown, and once that has happened, these bacteria are nearly impossible to wash out. The contamination is inside the seed, and the sprout grows from it.

Worse, the growing conditions are close to ideal for bacteria. Sprouting needs warmth and constant moisture for several days. The FDA's own wording is that if pathogenic bacteria are present in or on the seed, they can grow to high levels during sprouting, even under clean conditions. It adds that sprouts grown at home are also risky if eaten raw, which surprises people who assume home-grown means safer.

So the usual reassurance, that you can wash produce and be fine, does not transfer. There is nothing to wash off.

What is actually in them

The organisms most often involved are salmonella and shiga toxin-producing E. coli, both of which cause food poisoning rather than a specific pregnancy infection. That matters because it changes what you are protecting against. The NHS notes that salmonella is unlikely to harm your unborn baby directly, but you could get food poisoning that makes you seriously unwell, and being seriously unwell in pregnancy carries its own consequences.

FSANZ places raw seed sprouts on its listeria list as well, alongside other ready-to-eat foods that are eaten cold and can support bacterial growth. Listeriosis is the infection that can cross the placenta, and it is the reason the Australian list is stricter than the UK one across several foods.

Cooking is a complete answer

This is the part worth holding on to, because it means you do not have to give up the dishes.

The FDA's instruction is to cook sprouts thoroughly, and it says this significantly reduces the risk of illness. There is no separate pregnancy rule and no minimum time published for sprouts specifically. Practically, that means sprouts that have been stir-fried through, boiled in a soup, or added to a curry and heated until steaming hot are fine.

The dishes that catch people out are the ones where sprouts go in at the end, uncooked, as a garnish: pho, where a handful of raw bean sprouts is piled on at the table, bun cha and bun bo hue, pad thai with raw sprouts on the side, banh mi, Korean kongnamul muchim, and salad bar bowls.

With pho, the fix is straightforward and works: put the sprouts into the broth and let them sit rather than eating them raw off the plate. The broth is hot enough to do the job if you give it a minute and the sprouts go soft.

Eating out and reading labels

The FDA is unusually specific about restaurants. It tells people at higher risk to check sandwiches and salads bought at restaurants and delicatessens, because they may often contain raw sprouts, and to request that raw sprouts are not added to your food.

That is a reasonable thing to say at a counter, and staff hear it often. Sandwich chains in the US routinely add alfalfa sprouts; in the UK they are more common in health food shops, poke bowls, falafel wraps and supermarket salad pots than in mainstream sandwiches.

Packaged sprouts sold chilled are ready-to-eat products, which is precisely the category FSANZ and the NHS both warn about for listeria. The use-by date matters, but the date is not the issue here: the seed is.

If you have already eaten them raw

Almost certainly nothing follows. Outbreaks linked to sprouts are real and well documented, but they are outbreaks, which means the great majority of sprouts sold carry nothing at all. Eating a bowl of pho with raw sprouts on top is not something to act on retrospectively.

What to do instead is watch. The NHS advice for anyone who has eaten something that should be avoided in pregnancy is to get help from 111 if you feel unwell afterwards, if you have had vomiting and diarrhoea for more than 48 hours, or if you have symptoms of listeriosis. Say you are pregnant and say what you ate, because it changes what a clinician looks for.

Do not go looking for a test on the basis of exposure alone. Nothing is done preventively.

Where guidance differs

The United States is the most explicit. The FDA's food safety guidance for pregnant women names raw sprouts of any kind, names four specific varieties, warns about home-grown sprouts, and tells people to ask for them to be left off restaurant food.

Australia and New Zealand agree. FSANZ lists raw seed sprouts among the foods pregnant people should not eat, grouped with the other cold ready-to-eat foods on its listeria list.

The UK is silent. The NHS foods to avoid page names enoki mushrooms, pre-cut melon, bagged salad and vegetable pâté, but not sprouts. Given how itemised that list is, the omission looks deliberate rather than accidental, but the NHS has not published a reason.

Everyone agrees on cooking. No authority restricts cooked sprouts, and none suggests that any residual risk survives thorough cooking.
