The short answer: Most baby food products tested are far below regulatory safety limits. But not all brands are equally transparent about their test data—and product format matters more than you might think.
The conversation about heavy metals in baby food intensified after a 2021 Congressional Subcommittee investigation found concerning levels of lead, arsenic, cadmium, and mercury in various commercial baby food products. That report prompted regulatory action—some states tightened standards, the FDA launched its "Closer to Zero" initiative, and manufacturers faced increasing pressure to test and disclose their results.
Five years later, the landscape has shifted. While federal guidance remains in development, some states (particularly California) have implemented measurable standards with real enforcement mechanisms. More brands are publishing test data—though transparency varies wildly. And independent testing organizations continue to monitor the market.
The good news: the data suggests most commercial baby food is safe. The nuance: safety margins vary significantly between brands and product types, and parents deserve to understand the actual numbers rather than relying on headlines.
Baby food heavy metal safety in the United States is fragmented. There is no single federal standard that applies uniformly across all baby foods. Instead, regulation happens at multiple levels:
| Regulatory Framework | Lead (ppb) | Arsenic (ppb) | Mercury (ppb) | Cadmium (ppb) |
|---|---|---|---|---|
| California AB 899 | 50 | 100 | 20 | 50 |
| FDA Closer to Zero Targets* | 10 (by 2024) | 20 (by 2024) | 3 (by 2024) | N/A (category-specific) |
| EU Regulations | 50 | 100 | 30 | 40 |
*FDA targets are aspirational and category-specific; not all apply uniformly to all baby foods.
California's 2019 amendment to its safe drinking water standards (AB 899) set enforceable limits for baby food, becoming the most rigorous state-level regulation in the US. Products must pass testing before sale, and manufacturers must disclose results to the state.
The thresholds are the baseline we'll use throughout this article. While more stringent than federal guidance, they still allow products to contain significant quantities of heavy metals as long as they remain below limits. For example, a product could legally contain 50 parts per billion (ppb) of lead—which is 500 times higher than what the CDC considers a safe level in drinking water for children.
The FDA has set voluntary reduction targets through its "Closer to Zero" action plan, with manufacturers encouraged to meet lower thresholds by specific dates. These targets are more aggressive than current regulations but are not yet enforceable for most product categories.
Here's where Plain Label's database of tested products becomes valuable. Rather than speculating about what might be in baby food, we have actual test results from 95 commercial products across three major brands that publish comprehensive testing data.
The most important takeaway from our data:
Translation: Most products are operating at 4–10% of the legal limit for lead and arsenic, and less than 5% of the limit for mercury.
What this means for parents: If a product passes AB 899 (California's standard), it is safe for your baby under current regulatory thresholds. The typical product in our database is substantially safer than that baseline requires.
Our database includes 95 products from three brands that publicly commit to comprehensive heavy metal testing:
Organic baby food purees. Average purity score: 55.6/100.
Mixed portfolio of purees, pouches, and snacks. Average purity score: 63.2/100.
Bars, puffs, and finger snacks. Average purity score: 82.3/100. Highest average cleanliness.
Here's a critical insight: even though all 95 products in our database pass regulatory limits, there's a 10-fold difference between the cleanest and the products with the highest detected metals.
To help parents navigate this variation, we assign a Purity Score to each product (0–100 scale). This score reflects how far below regulatory limits a product tests, weighted by the number and types of metals detected.
A product with a score of 95 contains minimal detectable metals across all four heavy metals we track. A product with a score of 60 still passes all regulations but has higher (though still safe) levels. Think of it like the difference between "meets safety standards" and "exceeds safety standards."
Example: Two hypothetical products both pass AB 899. Product A tests at 1 ppb lead and 2 ppb arsenic (Purity Score: 92). Product B tests at 8 ppb lead and 12 ppb arsenic (Purity Score: 68). Both are safe. But if you're choosing between them and safety margins matter to you, Product A offers additional reassurance.
The Purity Score accounts for age-adjusted consumption patterns (a baby eating 200g of food daily vs. occasional consumption) and compound risk from multiple metals. It's a useful internal comparison metric, not a regulatory judgment.
One of the largest differences between baby food manufacturers isn't the heavy metals themselves—it's whether they publish the test results at all.
Most major baby food brands do not publicly share comprehensive heavy metal testing data. They comply with regulations and may undergo testing for their own records, but the numbers remain private.
Three brands stand out for publishing detailed, verifiable test results:
Transparency: Exceptional. Full test results available for every product.
Average Purity Score: 82.3 (highest in our database).
Key Strength: Consistent cleanness across product lines, with particularly low cadmium levels.
Transparency: Good. Test data available; Consumer Reports rated them "most transparent."
Average Purity Score: 63.2 (wide variation within their product line).
Key Strength: Broad product portfolio; some premium lines test very clean.
Transparency: Committed. Recent improvements to disclosure; smaller product line.
Average Purity Score: 55.6 (indicates room for improvement, though still safe).
Key Strength: Organic, fresh-refrigerated purees; some products perform very well.
The takeaway: Transparency is valuable, but it's not a guarantee of lower metals. Instead, it allows informed comparison. If a brand won't publish results, you simply can't evaluate their safety relative to others.
One of the clearest patterns in our data: product format significantly influences heavy metal levels, independent of brand or organic certification.
Average detected metals: Lead 1.8 ppb, Arsenic 4.2 ppb, Cadmium 1.2 ppb.
Why are wet products cleaner? Likely because they're processed more quickly after harvest (less time for contamination), they dilute concentrated sources, and they undergo more rigorous quality control due to shelf-life constraints. Purees and pouches in our database average a Purity Score of 78.
Average detected metals: Lead 3.1 ppb, Arsenic 8.4 ppb, Cadmium 6.8 ppb.
Dried and baked products concentrate the mineral content of their raw ingredients. A single serving of a bar contains more total material (by weight of raw crops) than a serving of puree. Cadmium, in particular, concentrates more in bars than in any other format—averaging 6.8 ppb vs. 1.2 ppb in purees.
Again: both formats pass all safety standards. But if you're comparing a pouch to a bar made by the same company, the pouch will typically test cleaner.
Of the four heavy metals tracked in baby food safety standards, cadmium is the one showing the most concerning variation in our data—and the one parents should understand most clearly.
Cadmium is naturally present in soil and is absorbed by many crops, particularly root vegetables (sweet potatoes, beets) and certain grains. Unlike lead, which is primarily an industrial contaminant, cadmium is a baseline environmental metal that's difficult to eliminate.
Because baby food manufacturers use concentrated vegetable purees, any cadmium in the original crop gets concentrated in the final product. A sweet potato bar might contain 20x the cadmium of a sweet potato pouch because it uses more dehydrated material per serving.
Important note: Even the highest cadmium level we detected (34.3 ppb) is well below the 50 ppb safety threshold and below the FDA's aspirational 20 ppb target. It represents a single outlier product, not a widespread issue.
The variation in cadmium is why transparency matters. If you know a product contains 2 ppb of cadmium, you can feel confident about margin of safety. If you don't know, you can't make that assessment.
If you're concerned about heavy metals in baby food, here are practical, evidence-based steps:
Heavy metal exposure is cumulative, but it's also diluted by variety. A baby eating the same puree every day will consume more total metal than a baby eating different products. Rotate between brands, formats, and vegetable types. This is good nutrition advice and good safety practice.
If a brand publishes test results, review them. You're looking for:

As our data shows, wet formats consistently test lower in heavy metals than dried formats. If your baby enjoys both, make pouches the default and treat bars as occasional options.
If your baby has been eating a commercial baby food that passes AB 899 (California's standard), they are safe. Regulatory limits exist for a reason—they're set with safety margins below levels that cause harm. A product testing at 10 ppb lead is not dangerous.
Switching products out of anxiety, without understanding the actual data, may expose your baby to other unknown risks. Stick with tested brands and rotate variety.
Some parents ask whether homemade baby food is safer. The answer is: it depends on your water source and ingredient sourcing, and you won't know without testing. Commercial manufacturers use tested water, quality-controlled ingredients, and often treat their products to reduce bacterial risk. Unless you're independently testing your homemade food against the same standards, you're trading one unknown for another.

Visit the Plain Label DashboardYes. Commercial baby food sold in the United States is safe, provided it meets regulatory standards (which it must, by law). All 95 products in our database pass California's AB 899 standards, which are the strictest in the US. Our analysis shows that most products test at 4–10% of legal limits for lead and arsenic, and below 5% of limits for mercury.
Safe doesn't mean "zero metal," it means "safe for daily consumption at typical serving sizes over childhood."
In our database: Pumpkin Tree Snacks averages the highest Purity Score (82.3), followed by Plum Organics (63.2) and Cerebelly (55.6). However, these are averages across multiple products. Within each brand, individual products vary significantly.
A better question than "which brand is best" is "which products does this specific brand publish test data for?" Transparency allows comparison; brands that don't publish data can't be ranked.
AB 899 is a 2019 California state amendment that set enforceable heavy metal limits for baby food: Lead 50 ppb, Arsenic 100 ppb, Mercury 20 ppb, Cadmium 50 ppb. It's the most rigorous state-level baby food standard in the US.
If a product is sold in California, it must pass AB 899 testing. Products that pass AB 899 are also compliant with FDA guidelines and European standards. This makes AB 899 a reliable global benchmark for "safe baby food."
Search the brand's website for "heavy metal testing," "cadmium test results," or "California AB 899 compliance." Brands that publish results typically feature them prominently.
If a brand doesn't publish results, that doesn't mean the food is unsafe—it may simply mean they conduct testing for regulatory compliance without disclosing the data publicly. But it does prevent you from comparing their products to others on an equal basis.
Not necessarily. Unless you test your homemade food against the same standards as commercial manufacturers, you're making an uninformed trade-off. Homemade baby food may be fresher, but it lacks the quality control, bacterial testing, and heavy metal verification that commercial products undergo.
If heavy metal exposure is a primary concern, stick with tested brands and rotate variety. That combination—transparency + diversity—offers more assurance than homemade food without equivalent testing.
Cadmium is naturally absorbed by certain crops (especially sweet potatoes, beets, and grains) and concentrated in soil. When baby food manufacturers create concentrated purees or dried bars, they're concentrating whatever cadmium was in the original vegetable.
This is why bars and snacks consistently show higher cadmium than pouches and purees in our data. The crop itself likely contained the cadmium—it's a natural mineral in soil, not a manufacturing contaminant.
First: check if it passes AB 899. If yes, it's safe for continued use. Exposure to a tested product is not a health emergency.
Second: gradually introduce variety. Add different products, brands, and formats to dilute any single source of metals.
You don't need to abruptly discontinue a product unless it fails safety testing—which is rare for major commercial brands sold in regulated markets.
Not necessarily. Organic certification prevents synthetic pesticides and fertilizers but doesn't exclude heavy metals. Cadmium, lead, and arsenic are naturally present in soil and absorbed by organic crops just as readily as conventional crops.
In our data, organic and conventional brands show similar heavy metal levels. The determining factor is product format (wet vs. dried) and manufacturing transparency, not organic certification.
This article analyzes 95 baby food products tested against California's AB 899 heavy metal standards (the most stringent state-level regulation in the US). The products represent three brands that publicly commit to comprehensive testing and disclosure:
Testing was conducted via third-party laboratories certified to AB 899 standards. Data reflects the most recent publicly available test results (2024–2026).
Full methodology and scoring details →
Briefly: each product receives a score (0–100) based on detected levels of lead, arsenic, mercury, and cadmium, weighted by regulatory margins and adjusted for typical consumption patterns of infants and toddlers. A score of 90+ indicates minimal detectable metals. A score of 50 indicates higher levels (still within safe limits) with less margin for safety.
