Infant Formula, Powder (Non-Soy)
Powdered non-soy infant formula has usable but incomplete heavy-metal occurrence evidence. Structured rows summarize published concentration data; they do not establish certification limits.
- Evidence status: modeled or limited evidence, with one reconstructable FDA prepared-for-feeding dataset for total arsenic, lead, cadmium, and total mercury.
- Main concern: infants are the exposed population, so row-fit, basis matching, and non-detect handling matter before any standards interpretation.
- Best use: read the summaries first, then use the source tables below only when you need the underlying evidence.
This page is the public evidence page for powdered non-soy infant formula. It is organized around source-backed product concentration evidence, with exposure estimates and broad formula studies separated so they do not get mistaken for direct ppb product measurements.
Heavy Metal Index pages are written for several audiences at once. Each entry point below names where to start if you are reading the page with a specific question in mind.
- Brand legal and regulatory affairs
- Start with the Methodology section for the speciation, basis, and non-detect rules that govern every numeric claim, then the Literature Evidence Summary for source-traceable concentration evidence by analyte. Every numeric claim links to its source page; the Sources block at the bottom is the citations list, written to be quoted into a Daubert brief without further editing.
- Retailer quality and compliance
- The Federal / Regulatory Limits vs Field Findings section compares the applicable regulatory cap to the cited field evidence on a like-for-like basis (with basis conversion shown when conversion is well-defined, and a methodology anchor when speciation differs). The Literature Evidence Summary gives source count and confidence rating per analyte.
- Brand QA and product development
- Use the Lab Result Comparator to position a single lab value inside the cited literature for this matrix, against the applicable regulatory cap, with basis conversion explicit if applied. The comparator covers all ten HMT&C analytes and links to mitigation guidance per analyte.
- Regulators, journalists, and adversarial readers
- Every numeric claim on this page traces to a source page in the Sources block. The Methodology section states the rules that govern interpretation; the Evidence Governance note explains what this page is and is not (literature evidence, not HMT&C certification thresholds).
- HMT&C staff (internal)
- The threshold-selection arithmetic (percentile statistics, clean / dirty subcategory designation, CC eligibility) lives on the staff workbench snapshot at infant-formula-powder-non-soy, not on this public page.
Methodology
This page reports what the cited sources say about heavy-metal concentrations in non-soy powdered infant formula. The summary tables and inventories below are governed by a fixed set of methodology rules so the evidence is interpretable and auditable. The rules are stated here once and referenced from every section that depends on them.
Speciation is treated as non-substitutable. Inorganic arsenic (iAs) and total arsenic (tAs) are reported separately, because the toxicology and the regulatory ceilings for each are different. Methylmercury (MeHg) and total mercury (tHg) are reported separately for the same reason; tHg is not used as a proxy for MeHg, and a tHg measurement does not close a MeHg evidence gap. Total chromium (Cr) is not interpreted as hexavalent chromium (Cr-VI) unless the source explicitly speciates Cr-VI.
Basis is preserved and labeled, never silently converted. Concentrations in formula can be reported on at least three bases: powder as placed on the market, powder prepared for feeding (reconstituted with water at the manufacturer-specified dilution), or formula as consumed by an infant. Values on different bases are not directly comparable. Each table below labels the source basis explicitly. Where a basis conversion is needed for context, the conversion factor and assumptions are stated alongside the converted value, and the converted value is marked as indicative rather than direct.
Non-detect handling. Where a source reports a value below its limit of detection (LOD) or limit of quantification (LOQ), this page preserves the source’s reported handling. The 2026 FDA special survey is summarized below using the lower-bound convention <LOD = 0, which is conservative for upper-tail statistics. Other sources are summarized as the source itself reported (mean, median, range, or category statistics).
Source pooling is avoided. Aggregate statistics are not computed by pooling sample values across sources whose LOQs, sampling periods, geographies, and analytical bases differ. When the page reports source-level summary statistics, those summaries are the source’s own, not a re-aggregation across the cited literature. Cross-source pooling, when needed for standards work, is performed in staff tooling with documented basis adjustments and is not published on this page.
Row-fit and matrix-axis labeling. Sources are classified by how cleanly their reported scope matches non-soy powdered infant formula. Matrix-axis labels are exact when the source explicitly identifies the protein basis (cow milk based, milk based, or non-soy) and partial or unknown when the source uses a broad term (“infant formula”) or does not split soy from non-soy. Format-axis labels are exact when the source identifies powder, partial when the source mixes powder with ready-to-feed liquid, and unknown when the source does not state. Row-fit determines whether a source contributes direct evidence or supporting context.
Evidence tiers. A-tier sources are peer-reviewed primary studies, government reports, and authoritative meta-analyses. B-tier sources are industry white papers, NGO reports, and trade publications. C-tier sources are news, blog, and press material. Synthesis on this page leans on A-tier. Every cited source on this page is A-tier as of the last update.
Confidence rating. Source-count confidence is reported as low (1 to 2 contributing sources), medium (3 to 10), or high (more than 10), per the wiki’s standing convention. Confidence reflects volume and agreement of evidence, not regulatory pass-fail status.
Standards-program math sits elsewhere. Percentile selection, clean and dirty subcategory comparator selection, regulatory-ceiling adjudication, and final certification threshold decisions are tracked in the Heavy Metal Tested and Certified (HMT&C) staff workbench and are not published on this page. The values on this page are literature evidence, not certification thresholds.
Literature Evidence Summary
The table below summarizes what the peer-reviewed and government literature cited on this page reports for heavy-metal concentrations in non-soy (cow milk-based), powder infant formula. Values are pulled directly from cited sources without re-aggregation; pooling, percentile selection, and threshold math sit in the staff Standards Workbench rather than this public page.
Methodology rules for speciation, basis preservation, non-detect handling, and source pooling are stated in the Methodology section above and apply to every row below.

Federal / Regulatory Limits vs Field Findings
This is the fast comparison view for standards developers, regulators, retailers, brands, and legal teams. It shows the applicable federal or regulatory limit next to the current field-evidence state. It is not an HMTc pass/fail table; technical distributions remain in the evidence sections below.
| Metal | Federal / regulatory limit | Actual field finding | Decision read | Evidence |
|---|---|---|---|---|
| lead (Pb) | eu2023-contaminants-maximum-levels: EU European Commission maximum level: 20 ug/kg Pb. Scope: infant formulae, follow-on formulae, and young-child formulae placed on the market as powder. Basis: product as placed on market. | FDA 2026 prepared-for-feeding cow-milk powder subset: N=230; Pb detected 0.1-0.6 ug/kg; values are not powder-as-placed. | Indicative comparison. Cited range 0.1 to 0.6 ppb prepared-for-feeding converts to approximately 0.8 to 4.8 ppb powder-as-placed at the conservative 1:7 reconstitution (1 g powder per 7 g water), within 20 ppb cap (infant formula powder placed on the market) on the converted basis. See the page Methodology section for basis-conversion assumptions. | eu2023-contaminants-maximum-levels; fda2026-infant-formula-toxic-elements-special-survey |
| cadmium (Cd) | eu-2023-915-cadmium: EU European Commission maximum level: 10 ug/kg Cd. Scope: infant formulae, follow-on formulae, food for special medical purposes intended for infants and young children, and young-child formulae placed on the market as powder and manufactured from cow’s milk proteins or cow’s milk protein hydrolysates. Basis: product as placed on market. | FDA 2026 prepared-for-feeding cow-milk powder subset: N=230; Cd detected 0.1-1.3 ug/kg; values are not powder-as-placed. | Indicative comparison. Cited range 0.1 to 1.3 ppb prepared-for-feeding converts to approximately 0.8 to 10.4 ppb powder-as-placed at the conservative 1:7 reconstitution (1 g powder per 7 g water), compared against 10 ppb cap (infant formula powder manufactured from cow’s milk proteins or hydrolysates) on the converted basis. See the page Methodology section for basis-conversion assumptions. | eu-2023-915-cadmium; fda2026-infant-formula-toxic-elements-special-survey |
| arsenic-inorganic (iAs) | eu2023-contaminants-maximum-levels: EU European Commission maximum level: 20 ug/kg iAs. Scope: infant formulae, follow-on formulae, food for special medical purposes intended for infants and young children, and young-child formulae placed on the market as powder. Basis: product as placed on market. | FDA 2026 reports total arsenic for this formula subset; no comparable inorganic arsenic field row is loaded. | No conversion offered.

Evidence Governance
Public evidence label: Modeled or limited evidence.
This page is part of the Category 1 Evidence Fitness pilot. It summarizes source-backed occurrence evidence, partial distributions, and data gaps for this product row. Existing cited tables remain public page-level synthesis; value-level extraction and standards review are tracked separately in staff tooling.
This page does not publish or justify HMT&C certification limits. Public Index pages show what the cited sources say, what is still uncertain, and where readers can verify the evidence trail.
Lead Benchmark Context
HMI normalizes this row’s lead benchmarks to ppb so regulatory ceilings, exposure screens, and occurrence values can be compared on one concentration scale. The values below do not all mean the same thing: FDA and EU entries are regulatory context, Prop 65 is a serving-based exposure screen, and source tables on this page remain occurrence evidence.
| Reference point | Lead ppb view | Basis | How to use it |
|---|---|---|---|
| Current FDA | Not established | No current formula-specific FDA lead action level | FDA 2025 processed-baby-food lead guidance excludes infant formula |
| EU 2023/915 | 20 ppb | as placed on market as powder | EU maximum level. |
| Prop 65 MADL screen | 5 ppb | Illustrative 100 g/day powder-intake screen; formula-specific exposure model required | Derived from the 0.5 ug/day lead MADL using 500 ÷ grams/day; not a product-specific food limit. |
| HMTc standards use | ppb-normalized context | All values are shown in ppb, but the FDA entry is a not-established status and the Prop 65 value is an exposure conversion, not a commodity limit. | Do not borrow FDA processed-baby-food action levels for formula; use basis-matched occurrence data and the EU powder ceiling as external legal context. |
No U.S. FDA formula-specific lead action level is currently established; the EU powder ceiling is a legal backstop, not a clean-product target.
Full crosswalk: lead-benchmark-context.
Page Completeness
The strongest row-fit evidence on this page is cow-milk formula concentration data from China, Brazil, the United Kingdom, Canada, and pooled European market baskets, plus a 2026 FDA prepared-for-feeding sample-level dataset of 230 cow-milk powder formulas covering lead, cadmium, total arsenic, and total mercury. The peer-reviewed literature and government datasets cited below give consistent direct evidence for those four analytes on this matrix.
Remaining gaps in the cited literature are concentrated in three places. First, nickel, aluminum, hexavalent chromium, tin, and inorganic arsenic in non-soy powdered formula are documented mostly by summary statistics (means, medians, or ranges) rather than by sample-level distributions, which limits how confidently the literature can characterize the upper end of each analyte. Second, methylmercury in formula is a documented data gap; total mercury values cannot substitute because the toxicology of methylmercury and inorganic mercury differs. Third, several cited sources do not separate powder from ready-to-feed liquid, do not separate non-soy from soy-based formula, or report exposure estimates rather than product concentrations; those sources can support context but cannot anchor a non-soy powder distribution on their own.

Structured Concentration Rows
The FDA 2026 special survey is the first source in this row that gives a reconstructable product-label subset for several metals. These values are expressed as prepared for feeding, so they should not be silently pooled with dry-powder-as-sold ppb values. The extraction below is included as a traceability appendix, not as a public standard. The full sample-level dataset is maintained in the staff Standards Workbench. fda2026-infant-formula-toxic-elements-special-survey

The Digest formula papers add useful source-scope rows, but they mostly report means, medians, ranges, or maxima rather than full product-level distributions. These rows support the evidence pool and show high-end source context; they do not by themselves set public limits.

Broad Product Context: Author-Scope Index
The sources below are catalogued as product-context candidates for this row. The “Author-scope row-fit” column states what the authors actually resolved on each axis: matrix (cow milk-based, soy-based, rice-based, non-rice, or unresolved) and format (powder, ready-to-feed liquid, concentrated liquid, dry, or unresolved). A source counts toward this row’s evidence pool only once; rows marked “Cross-reference” already appear as direct evidence elsewhere on this page and are not counted again here.

Internal Standards Boundary
This public page stops at evidence inventory and traceability. Percentile calculations, clean/dirty comparator selection, LOQ fallback decisions, confidence review, regulatory-ceiling adjudication, and final standards decisions are tracked in the staff standards workbench rather than published as public page content.
The values above should therefore be read as source-reported or structured evidence context. They are not HMT&C candidate standards, final limits, or brand pass/fail criteria.
Evidence Used For This Row
The direct row-fit evidence is strongest when a study measures cow-milk, milk-base, or powdered milk formula as a product concentration. Chung 2021, Almeida 2022, FSA 2016, Dabeka 1987, Pandelova 2012, and Soares 2000 are therefore more useful for this row than broad baby-food papers, but each still has limitations that require AI adjudication before standards use.
The largest interpretive issue is scope. China-market, Brazil-market, UK-market, Canada-historical, EU-pooled-basket, and U.S. prepared-for-feeding values should not be silently merged without basis matching, AI row-fit adjudication, and jurisdiction metadata. They can show what has been observed in formula, and they may contribute to an aggregate evidence pool when the standards workflow can document comparability and 95% confidence.
Exposure Estimates From Formula Consumption
Gardener 2019 is useful because it reports infant exposure estimates from formula consumption. It is not a product concentration table and should not be used as ppb product-limit evidence.
| Metal | Product or exposure scope | N | Highest exposure estimate | Unit | Interpretation use | Citation |
|---|---|---|---|---|---|---|
| Pb | Formula exposure estimate for 4-month-old infant consuming 31 oz/day | 91 | 2.68 | ug/day | Exposure context only, not ppb product concentration. | 7 |
| Cd | Formula exposure estimate for 4-month-old infant consuming 31 oz/day | 91 | 23.33 | ug/day | Exposure context only, not ppb product concentration. | 7 |
French TDS Category Rows
Chekri 2019 reports French infant formula, follow-on formula, and growing-up milk values as consumed after preparation; it does not separate powder from ready-to-feed, soy from non-soy, or cow-milk from other formulas, so these rows support broad formula occurrence context rather than a row-specific product distribution. Chekri 2019
| French TDS row | N | Basis | Al mean / max | tAs mean / max | Cd mean / max | Cr-total mean / max | Ni mean / max | Sn mean / max |
|---|---|---|---|---|---|---|---|---|
| Infant formulae | 28 | as consumed | 196 / 585 ppb | 1.61 / 4 ppb | 0.39 / 1 ppb | 20.8 / 38 ppb | 25.9 / 50 ppb | 42 / 42 ppb |
| Follow-on formulae | 34 | as consumed | 276 / 1140 ppb | 1.68 / 3 ppb | 0.43 / 2 ppb | 22.1 / 78 ppb | 26.5 / 50 ppb | 42 / 42 ppb |
| Growing-up milks | 9 | as consumed | 189 / 724 ppb | 2.11 / 4 ppb | 0.71 / 4 ppb | 27.7 / 61 ppb | 25 / 25 ppb | 42 / 42 ppb |
Row Relationship
This row is the clean-benchmark counterpart to infant-formula-powder-soy-based for the row architecture relationship covering Al, Ni, and Cd.
Why This Category Is High-Risk
A 2025 global scoping review of baby foods and infant formulas reported heavy-metal detections in 63 percent of evaluated infant-formula determinations, with Pb, Cd, As, and Hg each detected in formula items; in the review’s primary-protein-source subgrouping, Pb was detected in 73 percent of cow-based formula items and Cd in 44 percent of cow-based formula items. 8
A 2012 arsenic speciation study reported total arsenic concentrations of 2 to 12 ng/g in 15 infant formulas without organic brown rice syrup; because 1 ng/g equals 1 ug/kg, this corresponds to 2 to 12 ppb total arsenic in formula powder, though the study does not isolate non-soy formula powder as a row-specific category. 6
A 2018 infant biomarker study cited prior work reporting total arsenic in formula powder up to 12.6 ug/kg, but the study does not separate soy-based from non-soy powdered formula. 9
A 2024 analytical study of European baby foods included powdered milk and reported that cadmium and lead were below the study LOD in all samples, while mercury was detectable in all samples and one powdered-milk sample had the highest estimated nickel intake in the study at 9.43 ug/kg body weight per day. 10
Non-soy-specific risk characterization remains incomplete.
What Drives Variance Across Brands
The promoted formula scoping review separates cow-based, soy-based, specialty, and nonspecified formulas, but it does not resolve powder-versus-ready-to-feed differences for this row. 8
The promoted powdered-milk analytical study resolves powder format but does not resolve soy versus non-soy formula. 10
Pandelova 2012 reported higher cadmium values in pooled soy-formula baskets than in pooled milk-formula and hypoallergenic-formula baskets, but pooled market baskets cannot be used as an individual-product percentile distribution. 5
Potential variance drivers for non-soy powdered formula should be documented only after sources distinguish formulation, ingredient inputs, processing equipment, packaging, and analytical method.
How The App Would Estimate Risk From An Ingredient List
The app model placeholder for this row should treat infant-formula-powder and non-soy-infant-formula as unresolved ingredient targets until source-backed contamination profiles exist.
Historical Recalls/Enforcement
See the page-level crosswalk above and regulatory-crosswalk-field-findings for current regulatory context; row-specific enforcement events remain pending.
No row-specific regulatory event has been added for this scaffold.
