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
Root vegetable purees is the aggregate ingredient label for infant-and-toddler purees made from root-vegetable bases including carrots, sweet potatoes, beets, parsnips, white potatoes, and similar tuber-and-root crops. Root vegetables accumulate Pb at the soil-root interface and Cd via cortical uptake during plant growth; this is documented in detail on the vegetables aggregate page. Root-vegetable purees inherit the source-vegetable metal profile, with Pb particularly concentrated relative to non-root vegetables because root vegetables grow directly in soil where legacy Pb-contamination concentrates.
The FDA Closer to Zero baby-food Pb action level differentiates root vegetable purees (20 ppb Pb) from non-root vegetable purees (10 ppb Pb) specifically because root vegetables carry the higher baseline Pb from soil-contact. The HMTc panel concerns for root vegetable purees are Pb (dominant), Cd, and trace iAs (in root vegetables grown in As-affected regions). Routes into root-vegetable-purees (Cat 1 row for infant root-vegetable products).
Ranges by source, region, and variety
Variance within root vegetable purees tracks the source-vegetable mix (carrot-only vs sweet-potato-only vs mixed-root-vegetable formulations), source-region soil profile (industrial-region or urban-garden production carries elevated Pb; commercial agricultural production sits at moderate baseline; certified-clean-soil production sits at lower baseline), and processing tier. Carrot-based purees are the most common single-vegetable infant product; sweet potato is the second-most-common; beet, parsnip, and white potato purees are less common.
Processing effects
Root-vegetable puree manufacturing involves washing, peeling (substantial Pb reduction by removing surface-deposited Pb), cooking, pureeing, and packaging (jar, pouch, or aseptic carton). Peeling is the dominant processing-stage mitigation lever for root-vegetable Pb; the peeled-and-cooked puree carries substantially lower per-mass Pb than the unpeeled raw vegetable. Sterilization (retort processing for jarred and pouched products) does not affect metals.
Ingredient-derivative risk
Root vegetable purees route into Cat 1 row root-vegetable-purees as the primary infant feeding product family. Derivatives include single-vegetable purees (carrot puree, sweet potato puree, beet puree) and mixed-root-vegetable purees. Mixed-meals products containing root vegetables alongside grains, proteins, or other ingredients dilute the per-product root-vegetable metal load.
Mitigation options
Sourcing levers (Supply-chain screening) are dominant. Source-vegetable origin specification favoring documented low-soil-Pb production regions; supplier-soil verification programs; and contractual Pb/Cd ceiling on incoming root vegetables for infant-product manufacturers operating to tight specifications.
Agronomic levers (Agronomic mitigation) operate at the root-vegetable cultivation stage. Soil pH management; soil amendments (biochar, lime); cultivar selection; remediation of urban-and-industrial production sites.
Processing levers (Processing mitigation) include thorough peeling for maximum Pb reduction; washing optimization; and avoidance of equipment-cleaning chemicals that could introduce metals.
Formulation levers (Formulation mitigation) include partial substitution of higher-Pb root vegetables (beet) with lower-Pb alternatives (carrot, sweet potato) where the matrix permits.
Testing and QC levers (Testing and quality-control mitigation) include lot-level Pb, Cd testing on finished root-vegetable purees against FDA Closer to Zero 20 ppb Pb action level for root vegetable purees (FDA 2025).
Packaging and storage levers (Packaging and storage mitigation) include glass-jar, pouch, or aseptic-carton packaging (modern infant-food packaging); avoidance of older soldered or unlined-metal storage.
