Dangerous foods for babies

A short, honest list of the foods that carry real risk, and the one thing that makes each of them safe. Almost none of these are foods to fear forever. They are foods to handle right: cut a certain way, cooked through, sourced ripe, or saved for a certain age. Each links to its full page.

Choking hazards

The size, shape, and hardness are the danger. Cut small the right way, cook soft, or wait.

🍇 Grapes · Quarter lengthwise, never whole or in round coins.
🍎 Apple · Cook soft or grate; no hard raw chunks.
🥕 Carrot · Cook soft or grate; no raw sticks or coins.
🌭 Hot dogs · Not before 12 months. Then peel, quarter lengthwise, and chop into tiny pieces; never round coins or long strips.
🍿 Popcorn · Wait until about age 4.
🍡 Mochi · Not until at least school age; dense and sticky, a top choking food.
🥜 Peanut · Never whole nuts; use thinned butter, powder, or puffs.
🌰 Whole nuts · No whole or chopped nuts until about age 4; use thinned butter or ground.
🍅 Cherry tomatoes · Quarter lengthwise, never whole or in round halves.
🫒 Olives · Pit, rinse, and quarter; keep small and go easy on the salt.
🍬 Marshmallows · Not for babies or young toddlers; squishes into the airway.
🍭 Hard candy and lollipops · Not for young children; a top choking hazard.
🍬 Fruit snacks and gummies · Gummy and chewy fruit snacks are a choking hazard; skip until about age 4.
🍮 Gelatin and jelly cups · Firm mini jelly cups are a serious choking hazard; never give them to young children.
⚠️ Konjac · Konjac jelly does not dissolve and is a serious choking hazard; keep it away from young children.
🍡 Kozhukattai · Sticky, dense rice-flour dumplings are a choking risk; mash small and supervise, or wait.
🌽 Baby corn · A firm tube shape, like a hot dog; cook soft, quarter lengthwise, then cut short. Never whole or in coins.
🥟 Gnocchi · Never a whole gnocco; dense and springy. Cut small and press flat.
🥟 Pierogi · Trim the chewy crimped rim and cut the rest small.
🫔 Tamale · The husk or leaf is packaging, not food. Remove it all before serving.
🐸 Frog legs · Full of thin needle-like bones; strip the meat off by hand, never serve on the bone.
🧀 String cheese · Pull lengthwise into thin strands; never a whole stick, chunk, or coin.
🌰 Almond flour · Ground only; whole and chopped nuts stay off the menu until about age 4.

Safe only when prepared right

A natural toxin that proper sourcing, cooking, or preparation removes. Done right, these are fine foods.

🟡 Ackee · Ripe or reputable canned only; unripe is toxic.
🥔 Cassava · Always peel and cook thoroughly; never raw.
🌿 Cassava leaves · Pound and boil thoroughly; never raw.
🥬 Chaya · Boil the leaves at least 20 minutes; never raw and not in aluminum.
🎋 Bamboo shoots · Boil thoroughly, or use canned; never raw.
🔴 Kidney beans · Fully cook (canned, or hard-boil dried); never undercooked.
🫐 Elderberry · Cook ripe berries and strain; never raw.
🌿 Rhubarb · Stalks only, cooked; the leaves are toxic.
🥔 Potato · Discard any green or sprouted potato; never raw.
🥒 Bitter melon · Remove the seeds and red arils; cook well.
⭐ Star fruit · Small amounts only; ask your pediatrician, especially with any kidney issue.
🟢 Custard apple · Remove every hard black seed; the seeds are toxic if crushed and a choking hazard.
🍄 Chanterelle mushroom · Wild mushroom with poisonous look-alikes; use only positively identified, trusted-source, well-cooked chanterelles.
🍃 Taro leaf · Toxic raw (calcium oxalate); boil thoroughly and discard the water before serving.
🌰 Candlenut · Toxic and purgative raw; only ever a tiny cooked, ground seasoning, never a snack nut.
🫘 Hyacinth bean · Cyanogenic raw; soak and boil fully in fresh water, then mash, before serving.
🫘 Sword bean · Toxic raw (canavanine and lectin); soak and boil thoroughly in fresh water first.
🌳 Beechnut · Toxic and a choking risk raw; must be roasted and ground, and it is a tree-nut allergen.
🫘 Scarlet runner bean · Lectin when raw or undercooked; boil hard until fully soft, then mash.

Cook through, or choose pasteurized

The risk is bacteria a baby cannot fight off well. Thorough heat or pasteurization removes it.

🌾 Wheat flour · Raw flour is a raw food: never let a child eat or play with raw dough or batter.
🌾 Whole wheat flour · Raw flour is a raw food: bake it through, no raw dough or batter.
🌾 Oat flour · Raw ground oats are untreated grain: cook before serving, no raw batter.
🍯 Honey · Never before 12 months (infant botulism).
🥪 Deli meat · Heat until steaming to kill listeria; also high in salt.
🥚 Egg · Cook until the white and yolk are firm; no runny egg.
🍗 Chicken · Cook to 165°F (74°C) on a food thermometer; color and juices are not a reliable doneness test.
🦪 Oysters · Fully cooked only; never raw shellfish.
🥛 Whole milk · Pasteurized only; as a main drink after 12 months.
🧀 Cheese · Pasteurized only; skip soft mold-ripened cheeses.
🧀 Brie · Pasteurized and cooked piping hot only; never raw soft cheese (listeria).
🥩 Kitfo · Cook the beef fully well-done; the classic raw or rare version is unsafe.
🍣 Sushi · No raw fish; only fully cooked rolls, and leave off the soy sauce.
🐟 Sashimi · Raw fish is never safe for babies; there is no cooked sashimi, so serve cooked fish instead.
🐟 Smoked salmon · Cold-smoked lox is uncooked (listeria); serve only fully cooked salmon.
🫙 Pate · Ready-to-eat spread (listeria) and high in vitamin A if liver; best skipped.
🍖 Salami and cured meats · Uncooked cured meat (listeria) and very high salt; best avoided.
🌱 Raw sprouts · Never raw; alfalfa and bean sprouts carry E. coli/salmonella. Cook thoroughly.
🍪 Raw cookie dough and batter · Never raw; raw egg (salmonella) and raw flour (E. coli). Bake fully.
🧃 Unpasteurized juice and cider · Pasteurized only; unpasteurized juice and cider can carry E. coli.
🐌 Periwinkle · A sea snail; cook fully and never raw, and the small firm shape is a choking risk, so skip for babies.

Too high in mercury

Mercury builds up in the body and can harm a baby’s developing brain. These are best avoided; choose lower-mercury fish like salmon, cod, or trout instead.

🐟 Swordfish and high-mercury fish · Avoid swordfish, shark, king mackerel, tilefish, marlin, and bigeye (ahi) tuna.
🐟 Pike · A large predatory freshwater fish; mercury varies by waterbody, so follow your state or local fish advisory, and default to salmon, cod, or trout for babies.
⚠️ Cobia · Runs high in mercury (it is not on the FDA/EPA lists for young children); choose a listed low-mercury fish instead.
⚠️ Amberjack · Runs high in mercury, and in some tropical reef regions can carry ciguatera toxin; best avoided for babies.

Not for babies

Foods and drinks that a baby simply should not have. A baby is small enough that even a little has an outsized effect.

☕ Caffeine · No coffee, tea, cola, or energy drinks; babies are extremely sensitive to caffeine.
🌿 Katuk · Raw katuk and its juice are tied to serious lung disease; not a safe food for babies.
💠 Borage · High in nitrates and liver-harming alkaloids; skip it, choose spinach or chard instead.
🟢 Bilimbi · Very high in oxalates; the fruit and juice can injure the kidneys, so not for babies.
⚠️ Pond apple · The seeds are poisonous and the unripe fruit is harmful; not a fruit for babies.

Frequently asked questions

What foods are most dangerous for babies?

Three kinds. Choking hazards (whole grapes, hot dog coins, whole nuts, popcorn, hard raw apple and carrot), foods with a natural toxin that only proper preparation removes (raw or undercooked kidney beans, cassava, bamboo shoots, rhubarb leaves, ackee), and foods that carry germs a baby cannot fight off (honey before one, raw or runny egg, undercooked chicken, raw shellfish, unpasteurized milk and cheese).

Which foods should never be given to a baby under one?

Honey is the clearest: never before 12 months, in any form, because of the risk of infant botulism. Cow’s milk as a main drink also waits until 12 months, and it should always be pasteurized. Hot dogs wait until 12 months too, and even then only peeled, quartered lengthwise, and chopped into tiny pieces. Whole grapes, whole nuts, and popcorn stay choking hazards well past the first birthday; the rules on this page say how to handle each one.

Are these foods off-limits forever?

Mostly no. Almost all of these are perfectly good foods once handled correctly: cut the right way, cooked through, sourced ripe, or offered at the right age. This page is about the how and the when, not a list of foods to fear.
