Why this commodity accumulates heavy metals
Non-soy infant formula is the default formula format in most markets, using cow-milk protein (intact, partially hydrolyzed, or fully hydrolyzed) or amino acids as the protein base. Heavy-metal load in non-soy formula comes from four primary pathways: the cow-milk ingredient (Pb, Cd at low background levels reflecting forage and water inheritance); the carbohydrate source (lactose, maltodextrin, corn syrup solids — generally low metal loads but trace iAs from corn-derived ingredients); the vitamin-mineral premix (Pb, Cd, Al contamination via mineral salt impurities, particularly calcium phosphate and iron salts); and the manufacturing water and processing infrastructure (Pb from leaded brass fittings in older infrastructure, contributing trace background). When the formula contains a rice-derived ingredient (rice starch, brown rice syrup), iAs from the rice pathway dominates the arsenic profile per Jackson 2012.
Non-soy formula carries a substantially different heavy-metal profile from soy-based formula because the cow-milk protein base does not concentrate Al, Ni, and Cd the way soy protein isolate does. The HMTc Cat 1 Step 0 lock splits non-soy from soy formula into separate product rows (infant-formula-powder-non-soy and infant-formula-rtf-liquid-non-soy) on this basis. The HMTc-panel concerns for non-soy formula are dominantly Pb (vitamin-mineral premix inheritance), iAs when rice-derived ingredients are present, and Cd from background mineral salts. Mercury and aluminum sit at trace levels under most reasonable formulations; the Thoerig 2025 U.S. systematic review documents this consistently.
Heavy metal contamination profile
The body-level analyte snapshot for non-soy formula follows the per-format pages: see infant-formula-powder-non-soy and infant-formula-rtf-liquid-non-soy for the format-specific concentration tables. The non-soy profile is dominated by trace Pb (≈1-10 ppb) and trace iAs (≈3-8 ppb), with Cd and Hg at near-LOQ background.

Ranges by source, region, and variety
Variance within non-soy infant formula tracks regional supply infrastructure (U.S./EU/emerging markets reflecting different mineral-premix supplier baselines), the manufacturer’s specification on incoming raw ingredients (testing of vitamin-mineral premix for Pb/Cd ceiling, rice-ingredient screening for iAs), the manufacturing water source quality, and the historical generation of the product line (post-2018 manufacturer responses to FDA’s Closer to Zero infant-rice-cereal action level have tightened iAs in rice-containing formulas). U.S.-market non-soy formula sits at the low end of the global range; the Eticha 2018 Ethiopian market sample documents higher per-analyte concentrations in emerging-market supply, consistent with weaker upstream raw-ingredient quality control.
Per-formulation variance: hydrolyzed cow-milk formula carries similar trace-metal load to intact cow-milk formula because the hydrolysis step does not introduce metals; amino-acid-based formula (elemental nutrition) carries a different mineral-premix profile reflecting the synthetic amino-acid feedstock. Rice-containing formulas (some “gentle” formulations include rice starch or brown rice syrup) carry elevated iAs from the rice pathway per Jackson 2012; these formulations should be flagged distinctly.
Processing effects
Non-soy infant formula manufacturing involves wet-mix preparation of cow-milk protein with carbohydrate, fat, and vitamin-mineral premix, followed by spray-drying for powder formats or sterile fill for RTF/concentrated liquid formats. Each step is a potential metal-introduction point: water-based pre-blending introduces background water-source Pb/Cd; spray-drying concentrates per-mass solids without removing metals; can-lining (for RTF liquid) introduces a Sn migration pathway in lower-quality can stock. The ICP-MS method validated in Pacquette 2016 is the operative analytical platform for routine in-process and finished-product testing.
Format-driven concentration: powder formula on a per-gram basis carries roughly 7× the analyte concentration of RTF liquid formula on a per-mL prepared-for-feeding basis (the 1:7 reconstitution factor). Comparisons across studies must respect this conversion; the EU 2023/915 prepared-for-feeding 10 ppb Pb maximum level translates to roughly 70 ppb on the powder basis.
Ingredient-derivative risk
Non-soy formula derivatives span the three format families: powder (most common), ready-to-feed (RTF) liquid, and concentrated liquid. Each Cat 1 Step 0 row variant (infant-formula-powder-non-soy, infant-formula-rtf-liquid-non-soy) carries similar per-mass-protein metal load on a like-for-like basis; reconstitution shifts the per-volume concentration. Specialty derivatives (lactose-free, anti-reflux, “gentle” formulas with rice-derived ingredients) carry product-specific profile shifts. Rice-containing variants specifically warrant separate iAs screening per Jackson 2012.
Mitigation options
Sourcing levers (supply-chain-screening) are the dominant intervention for non-soy formula and operationally tractable. Brand-side decisions include: vitamin-mineral premix supplier specification (testing of incoming premix for Pb, Cd, and trace Al against per-mass-in-finished-formula compliance targets); rice-ingredient avoidance for non-rice formulations (eliminates the iAs pathway entirely); upstream cow-milk supplier specification (forage-monitoring programs and water-source verification); and manufacturing-water quality specification (RO or equivalent for finished-formula water).
Agronomic levers (agronomic) operate at the cow-milk dairy-feed and dairy-water stage and at the rice-cultivation stage when rice ingredients are used. See milk-and-dairy and rice for upstream interventions.
Processing levers (processing) are limited at the formula-manufacturing stage; the metal load is in the raw ingredients. Water-treatment improvements and processing-equipment metal-leaching audits are the operative interventions.
Formulation levers (formulation) include the non-rice-ingredient substitution for “gentle” formulations (lactose-free with corn-syrup-solid carbohydrate base rather than rice-derived) and the vitamin-mineral premix supplier choice as a primary lever.
Testing and QC levers (testing-and-qc) are mature: lot-level Pb, Cd, iAs testing on finished non-soy formula against the EU 10 ppb Pb prepared-for-feeding ML, the 5 ppb Cd ML, and the 20 ppb iAs ML for infant-and-young-child food. The Pacquette 2016 ICP-MS method is the analytical-platform foundation.
Packaging and storage levers (packaging-and-storage) include can-lining specification (BPA-NI epoxy or food-grade alternative) to minimize Sn migration in RTF liquid formats, and avoidance of aluminum-foil-lined packaging for prepared-formula storage.
Regulatory limits that apply
- eu-2023-915 — EU Reg. 2023/915 sets binding maximum levels for infant formula: Pb 10 ppb prepared-for-feeding (≈70 ppb powder basis), Cd 5 ppb prepared-for-feeding, iAs 20 ppb prepared-for-feeding, Hg 20 ppb prepared-for-feeding. These apply to non-soy formula directly.
- fda2020-inorganic-arsenic-infant-rice-cereal — FDA Closer to Zero iAs framework covers rice-containing formula at the 100 ppb iAs action level.
- Codex Alimentarius CXS 72-1981 (infant formula) and CXS 156-1987 (follow-up formula) establish composition standards.
- California Prop 65 (california-prop65) Pb MADL applied to infant formula yields stringent serving-based screen.
- FDA Closer to Zero broader infant-food framework also covers non-rice infant foods; ongoing rulemaking will set quantitative action levels.
