Overview
This is a structural ingredient node created so product pages can link to a real wiki target. Occurrence values remain pending until a source is promoted for this ingredient.
Heavy metal contamination profile
Per-analyte snapshot derived from the machine-readable contamination_profile in the frontmatter above. data gap indicates the literature has been reviewed for this commodity-analyte combination and no usable occurrence data was found (a finding, not a placeholder). The Key sources column shows the top 2-3 contributing sources by year and sample size, with numbered wikilink aliases.

Contamination Profile State
Per-analyte state — populated, in progress, or declared data gap — is carried authoritatively in the machine-readable contamination_profile frontmatter and the contamination-profile table above. Ingredient-level values belong here; finished-product values belong on the relevant product-category page.

Why this commodity accumulates heavy metals
Meat-and-poultry purees (Cat 1 baby food) inherit their heavy-metal load from the source meat or poultry (see Beef, Poultry, Ham, Turkey, Chicken). The pureeing process combines muscle (and sometimes a small fraction of organ meat) with water, vegetables, or grain into a smooth texture for infant feeding. Commercial baby-food meat purees typically use muscle-only (avoiding organ-Cd), with chicken and turkey as the dominant species and beef and lamb less common.
The HMTc panel concerns are dominantly Pb (from source meat and from any added vegetable or grain ingredients) and Cd (from source meat, with organ-meat-free formulation reducing this contribution). Mercury is not a meat-and-poultry-puree concern because terrestrial herbivores do not bioaccumulate MeHg.
Ranges by source, region, and variety
Per-species: Chicken puree carries lower per-mass metal than beef puree from the same region (younger animals, shorter exposure). Turkey puree similarly. Lamb puree from certain regions can carry elevated Pb from grazing-pasture contamination.
Chekri 2019 characterizes French infant-toddler TDS including meat-and-poultry purees. Houlihan 2019 HBBF covers US-market baby food meat purees.
Production-system variance: Grass-fed and pasture-raised meat purees from documented clean-pasture regions carry lower Pb than feedlot-finished or industrial-feed meat purees from regions with documented feed-contamination.
Processing effects
Meat-and-poultry puree manufacturing (slaughter, deboning, mechanical separation or cubing, cooking, blending with water/vegetable/grain, pureeing, packaging) does not change source-meat metal content. Cooking concentrates per-mass metal slightly through water loss but per-jar total metal is approximately conserved. The added water or vegetable fraction in the puree dilutes the per-mass concentration relative to source meat.
Ingredient-derivative risk
Meat-and-poultry purees are themselves finished retail products. Toddler meal products combining meat puree with grain or vegetable bridge into Cat 1 toddler-bridging scope and Cat 7 adult-mixed-meal scope as the marketing-age boundary is crossed.
Mitigation options
Sourcing levers (Supply-chain screening) include single-source-region meat sourcing from documented low-Pb production areas (grass-fed regions, clean-feed-source operations), muscle-only specification (avoiding organ-Cd contribution), and supplier-feed-source verification.
Agronomic levers (Agronomic mitigation) operate at the upstream meat-production stage.
Processing levers (Processing mitigation) include cooking-method specification and water-vs-broth dilution in the puree formulation.
Formulation levers (Formulation mitigation) include species choice (chicken or turkey preferred over beef for lowest baseline metal load), muscle-only formulation, vegetable-or-grain dilution fraction adjustment.
Testing and QC levers (Testing and quality-control mitigation) include lot-level Pb and Cd testing on finished meat-and-poultry purees, particularly for products targeting infants under 12 months.
Packaging and storage levers (Packaging and storage mitigation) include the Sn-migration consideration for canned meat purees and food-contact-substance compliance for pouch and jar formats.
Regulatory limits that apply
- FDA 2025 Lead Action Levels for Processed Food Intended for Babies and Young Children — FDA Closer to Zero Pb action level of 10 ppb for processed meat baby foods.
- eu-2023-915 — EU Reg. 2023/915 sets Pb and Cd MLs for infant-and-young-child meat-based foods. Stricter than adult meat MLs.
- Codex CXS 193-1995 — Codex MLs apply.
- California Prop 65 (california-prop65) Pb MADL applies to meat-and-poultry purees sold in California.
