The truth about baby cereal and arsenic
Rice cereal has been the default first food for decades. New research and FDA action have changed the recommendation. Here's what to feed instead and why.
Feeding · Safety
TL;DR
Rice (and rice cereal specifically) absorbs inorganic arsenic from soil at higher rates than any other grain. Babies eating rice cereal as a main first food can take in 3-7x more arsenic than babies on oat or barley cereal. The FDA set its first-ever inorganic arsenic limit for baby rice cereal in 2020, and most brands now meet it — but oat, barley, and multigrain cereals remain the safer default first grains. If you do feed rice cereal, rotate it with other grains, rinse rice before cooking, and never make it the primary food source.
Health note: This is general information about food safety, not medical advice. If you're worried about exposures from a specific brand or product, talk to your pediatrician about whether testing is warranted.
The arsenic problem in a sentence
Rice plants take up arsenic from soil and water more efficiently than any other staple grain. When that arsenic is the inorganic form, it's classified as a carcinogen by the WHO and EPA. Babies eating high-rice diets — especially via rice cereal, which is concentrated rice — can end up with measurable urinary arsenic levels.
Why rice is different
Rice grows in flooded paddies. Flooded soil releases more arsenic into water, and rice plants absorb it especially well through their roots. The arsenic concentrates in the grain itself.
This isn't a contamination problem. It's how rice naturally grows. The fix isn't "find arsenic-free rice" — there isn't any. The fix is to feed less of it.
Different rice types differ, modestly:
- Brown rice: highest arsenic (the bran holds it).
- White rice: lower (bran is removed).
- Basmati from India: lower than US-grown rice.
- Jasmine from Thailand: lower than US-grown.
- US-grown rice from Texas, Arkansas, Louisiana: highest in US testing.
- US-grown rice from California: lower than the southern US states.
What the FDA changed
For decades, the FDA didn't have a limit for arsenic in baby food. In 2016 the agency proposed an action level. In 2020 it was finalized:
- 100 ppb (parts per billion) for inorganic arsenic in infant rice cereal.
That limit is enforceable, and most major brands have reformulated to meet it. The 2025 FDA "Closer to Zero" initiative expanded the focus to lead, mercury, and cadmium across all baby foods, with proposed limits for grain-based products generally.
However, the 100 ppb threshold isn't a "safe" level — it's a feasibility level. Lower is better. Multiple consumer-reports-style studies have shown that even meeting the 100 ppb limit, a baby eating 2+ servings of rice cereal per day for months has measurably higher arsenic exposure than one eating other grains.
The grains that are actually safer
Oat cereal
Oats absorb dramatically less arsenic than rice. Most baby oat cereals test at 1/10 the arsenic of comparable rice cereals. Brands: Gerber Single-Grain Oatmeal, Earth's Best Organic Oatmeal, Happy Baby Oatmeal.
Caveat: oats can have higher cadmium than some grains. Variety still wins.
Barley cereal
Barley also tests very low for arsenic. Mild flavor, easy on digestion. Less commonly sold pre-made than oatmeal but available from Earth's Best and some smaller brands. Easy to make from scratch with rolled barley and water.
Multigrain cereal
If the multigrain isn't rice-heavy, it offers the variety advantage of getting nutrients from multiple grains. Read the label: the first grain listed is the largest component. Skip "multigrain" cereals where rice is first.
Quinoa cereal
High protein, gluten-free, tests low for arsenic. Less common as a baby-specific product but can be made from scratch by cooking quinoa thoroughly and pureeing.
Track first foods and watch for variety
The first foods tracker helps you log which grains you've offered and what baby liked. Variety is the most important protection against any single contaminant.

Rice cereal isn't toxic. It's just not optimal. If you have a box already or your baby loves it, here's how to feed it responsibly:
- Don't make it daily. Rotate with oat, barley, and other grains. 1-2 servings per week is fine.
- Choose brands that publish testing. Happy Baby, Beech-Nut, and Earth's Best publish independent arsenic testing data.
- Rinse and cook rice the "Indian method" if making it from scratch. Rinse thoroughly, cook in 6 parts water to 1 part rice, drain off the cooking water. This reduces inorganic arsenic by 30-50%.
- Don't make rice products the main grain. If baby eats rice puffs, rice rusks, rice-based teething biscuits, AND rice cereal — that adds up fast.
The other heavy metals to know about
Arsenic isn't the only metal in baby food. The 2021 Congressional report and follow-up testing revealed elevated lead, cadmium, and mercury in many baby food brands.
Where they come from:
- Lead: Sweet potatoes, carrots, and other root vegetables from soils that historically had leaded gasoline contamination.
- Cadmium: Spinach, lettuce, sunflower seeds — leafy greens take it up from soil.
- Mercury: Fish, especially predatory fish. Less common in baby food than rice/arsenic.
The protective approach is the same as for arsenic: variety. A baby eating 8-10 different fruits and vegetables across the week has far less exposure to any single contaminant than a baby eating the same 2-3 items every day.
What about iron?
The historical reason for rice cereal as a first food was iron fortification. Rice cereal is iron-fortified because babies need iron at 6 months.
You can get iron from:
- Iron-fortified oat or barley cereal (just as much iron as rice cereal).
- Pureed red meat or chicken.
- Iron-rich beans, lentils, tofu.
- Iron-fortified formula (still the main source under 12 months).
If your baby was breastfed, iron stores from pregnancy run low around 6 months and you need to add iron-rich foods. Iron-fortified oat cereal is the easiest swap from rice cereal with the same nutritional benefit.
What to look for on the label
- "Iron-fortified" or "Single grain oat" or "single grain barley": Good first cereal.
- "Rinsed" or "tested for heavy metals": A brand putting in effort.
- Multigrain with rice not first: Acceptable rotation.
- Brown rice cereal as the only grain: Reconsider.
The brands publishing test data (as of 2026)
Brands that voluntarily publish heavy-metal testing results in 2024-2026:
- Happy Baby
- Beech-Nut
- Earth's Best
- Gerber (selected products)
- Once Upon a Farm
- Cerebelly
Brands that have been criticized in independent testing reports (always check the most current data, this changes):
- Sprout
- Plum Organics (older testing — they've reformulated)
- Walmart Parent's Choice (varies by product)
This isn't a reason to panic or throw out everything. It's a reason to rotate brands and grains.
The bottom line for first foods
Start with oat or barley cereal at 6 months. Rotate with multigrain. Use rice cereal sparingly if at all. Add iron-rich protein foods (meat, beans, tofu) within the first month of solids. Vary the cuisine, the brands, the colors. Variety is your most powerful tool against any single contaminant in the food supply.
When to call your pediatrician
- If your baby has been eating rice-heavy meals (cereal, rice puffs, rice rusks) for several months and you want a blood lead/arsenic test.
- If you're seeing signs of developmental delay you're worried about.
- If your baby is on a restricted diet (rice-only, dairy-elimination) for medical reasons and you want to confirm balanced nutrition.
- Before making major dietary changes for a baby with food allergies or growth concerns.
