Infant Formula, RTF Liquid (Non-Soy)
This page is a structural scaffold for HMTc Category 1 row 3. One broad infant-formula source has been promoted; ready-to-feed-specific and Al/Ni-specific evidence is still pending.
Who this page is for
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
- Ready-to-feed-specific occurrence evidence on this matrix is thin; the Literature Evidence Summary reports source count and confidence rating per analyte so the gaps are explicit. Compare with the non-soy powder format-sibling for the more populated matrix.
- Retailer quality and compliance
- The Federal / Regulatory Limits vs Field Findings section compares the applicable regulatory cap to cited field evidence. Note that ready-to-feed liquid evidence often comes from prepared-for-feeding studies that need a basis caveat before comparison.
- Brand QA and product development
- Use the Lab Result Comparator to position a single lab value inside the cited literature for this matrix.
- Regulators, journalists, and adversarial readers
- Every numeric claim traces to a source page. The Evidence Governance note explains what this page is and is not (literature evidence, not HMT&C certification thresholds).
- HMT&C staff (internal)
- Threshold-selection arithmetic lives at infant-formula-rtf-liquid-non-soy, not on this public page.
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: 10 ug/kg Pb. Scope: infant formulae, follow-on formulae, and young-child formulae placed on the market as liquid. Basis: product as placed on market. | FDA 2026 ready-to-feed cow-milk subset: N=20; Pb detected 0.2-0.5 ug/kg; ready-to-feed values are the relevant liquid basis. | Direct comparison available; matrix, analyte species, and unit basis match. Not an HMTc certification limit. | eu2023-contaminants-maximum-levels; fda2026-infant-formula-toxic-elements-special-survey |
| cadmium (Cd) | eu-2023-915-cadmium: EU European Commission maximum level: 5 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 liquid and manufactured from cow’s milk proteins or cow’s milk protein hydrolysates. Basis: product as placed on market. | FDA 2026 ready-to-feed cow-milk subset: N=20; Cd detected 0.09-0.7 ug/kg; ready-to-feed values are the relevant liquid basis. | Direct comparison available; matrix, analyte species, and unit basis match. Not an HMTc certification limit. | eu-2023-915-cadmium; fda2026-infant-formula-toxic-elements-special-survey |
| arsenic-inorganic (iAs) | eu2023-contaminants-maximum-levels: EU European Commission maximum level: 10 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 liquid. 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. Regulatory ceiling is on inorganic arsenic; cited occurrence row reports total arsenic. The two are toxicologically and regulatorily distinct. See the page Methodology section for the non-substitutability rule on speciation. | eu2023-contaminants-maximum-levels; fda2026-infant-formula-toxic-elements-special-survey |
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 tracking is maintained in the staff Standards Workbench.
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.
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), ready-to-feed liquid 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.
| Analyte | Subcategory | Reported concentration range | Detection rate | Applicable regulatory cap | Sources | Confidence | Basis |
|---|---|---|---|---|---|---|---|
| Al | non-soy (cow milk-based), ready-to-feed liquid (direct row-fit) | mean 437 ppb (1 source); highest reported 3442 ppb | 100% detected (67/67, Dabeka 2011, as-consumed) | No applicable cap loaded | 4 cited | medium (4 sources) | as-consumed |
| Ni | non-soy (cow milk-based), ready-to-feed liquid (summary-only / supporting context) | highest reported 9 ppb | Sample-level detection rate not reported | No applicable cap loaded | 1 cited | low (1-2 sources) | as-consumed |
| Cd | non-soy (cow milk-based), ready-to-feed liquid (direct row-fit) | mean/median 0.09 to 0.27 ppb (3 sources); highest reported 1.26 ppb | 100% detected (67/67, Dabeka 2011, as-consumed) | eu-2023-915-cadmium: 5 ppb (product as placed on market) | 4 cited | medium (4 sources) | prepared-for-feeding; as-consumed |
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 | 10 ppb | as placed on market as liquid | EU maximum level. |
| Prop 65 MADL screen | 0.625 ppb | Illustrative 800 g/day ready-to-feed 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 compare RTF formula to dry-powder limits; use prepared/liquid occurrence data and the EU liquid ceiling as external legal context. |
RTF formula usually has low ppb concentrations because it is already diluted, so serving-based exposure screens can be much lower than legal ceilings.
Full crosswalk: lead-benchmark-context.
Scaffold Status
- Page state: evidence-backed scaffold; row-specific synthesis remains incomplete.
- Source coverage: measured-values table populated from promoted A-tier sources; row-fit caveats remain in the table.
- Next ingest target: formula-specific Al, Ni, and Cd data for non-soy ready-to-feed liquid infant formula.
- Ingredient targets are unresolved app-taxonomy placeholders, not source-backed typical-ingredient findings.
Measured Values And Concentration Evidence
Direct ready-to-feed liquid evidence is available from the UK survey. Values are liquid concentrations in ug/L, displayed as ppb-equivalent for water-like liquids.
| Analyte | Evidence scope | Reported value | Approximate ppb equivalent | Source | Row-fit caveat |

Extracted Formula Concentration Rows
The FDA 2026 special survey provides a product-label subset for ready-to-feed cow milk-based formula, expressed as prepared for feeding. Standards review still needs basis matching, jurisdiction metadata, and confidence review. The full sample-level dataset is maintained in the staff Standards Workbench. fda2026-infant-formula-toxic-elements-special-survey

French TDS Category Rows
Chekri 2019 reports French formula categories as consumed after preparation. These values are liquid-consumption-basis context, but the source does not isolate commercial ready-to-feed products or non-soy status. 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 |
Row Relationship
This row is the clean-benchmark counterpart to infant-formula-rtf-liquid-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% of evaluated infant-formula determinations; in its primary-protein-source subgrouping, Pb was detected in 73% of cow-based formula items and Cd in 44% of cow-based formula items. collado-lopez2025-heavy-metals-baby-food-formula
Ready-to-feed-specific risk characterization for Al and Ni remains pending.
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. collado-lopez2025-heavy-metals-baby-food-formula
Potential variance drivers for non-soy ready-to-feed formula should be documented only after sources distinguish formulation, water 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-rtf-liquid 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.
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.
