Root and Tuber Vegetables
Below-ground vegetables: carrots, potatoes (white, red, yellow, fingerling), beets, sweet potatoes, parsnips, turnips, rutabagas, radishes, yams, jicama, celeriac. No within-row split per Cat 4 lock; sweet potato data gap flagged in Step 0E. HMTc tests at the ‘as consumed’ basis (potatoes with skin if commonly eaten with skin; peeled for product-form variants).
This page is a Step 0 lock scaffold for Cat 4 Row 7. Literature evidence will be populated as routed source pages accumulate per the synthesis workflow in CLAUDE.md Part 9. The Step 0 lock document at Category4_Step_0_Output_LOCKED.md is the canonical reference for the row’s clean-vs-contaminated framing and platform attribution.
Who this page is for
Brand legal teams evaluating HMTc Cat 4 certification for the Root and Tuber Vegetables row need to know what the cited literature reports per panel metal, what the applicable regulatory caps are, and how this row relates to its clean-contaminated pair (when applicable). Retailer compliance teams stocking the produce, dried-goods, and snack aisles need the row-level assortment-eligibility view. HMT&C certification thresholds for products in this row are developed under the certification program at heavymetaltested.com, not on this page.
Methodology
This page reports what the cited sources say about heavy-metal concentrations in the Root and Tuber Vegetables row. Speciation is non-substitutable per CLAUDE.md Part 14 (iAs vs tAs, MeHg vs tHg, Cr-VI vs total Cr). Basis is preserved (as-sold or as-consumed depending on the product form). Non-detect handling follows each source’s convention. Pooling avoided across LOD/LOQ, period, geography, and analytical-basis differences. HMT&C certification thresholds for products in this row are developed under the certification program at heavymetaltested.com, not on this page; this public page reports literature evidence only.
Cat 4 lock empirical basis: Pass 2 occurrence-data extraction from the heavymetalindex.com wiki corpus (build claude/zealous-bhabha-d422c9, 896 source pages). The Step 0 lock document at Category4_Step_0_Output_LOCKED.md records the splitting decisions and platform attributions; this row inherits its scope from that document.
Literature Evidence Summary
Literature Evidence Summary
The table below summarizes what the peer-reviewed and government literature cited on this page reports for heavy-metal concentrations in Root and Tuber Vegetables. 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 |
|---|---|---|---|---|---|---|---|
| Pb | Root and Tuber Vegetables (no contributing evidence loaded) | No concentration data loaded for this analyte | Sample-level detection rate not reported | No applicable cap loaded | 0 | data gap | Basis not reported |
| Cd | Root and Tuber Vegetables (no contributing evidence loaded) | No concentration data loaded for this analyte | Sample-level detection rate not reported | No applicable cap loaded | 0 | data gap | Basis not reported |
| tAs | Root and Tuber Vegetables (no contributing evidence loaded) | No concentration data loaded for this analyte | Sample-level detection rate not reported | No applicable cap loaded | 0 | data gap | Basis not reported |
Source Evidence Inventory
_Hand-curated section. Populated by the synthesis pass as Cat 4 sources route to this row. Initial scaffold state: zero contributing sources. The Cat 4 corpus search prioritizes sources reporting concentration data on the specific commodity in this row; broad-scope produce surveys are filed under the master.
Broad Product Context: Author-Scope Index
Pending: regenerated by tools/evidence/apply-product-broad-context.mjs once broad-scope Cat 4 sources route to this page.
Federal/Regulatory Limits vs Field Findings
Pending. Cat 4 regulatory landscape: Codex GSCTFF and EU Regulation 2023/915 set finished-product limits on fruits and vegetables (Pb, Cd) and on specific commodities (e.g., spinach Cd at 0.20 mg/kg per eu-2023-915); FDA Closer-to-Zero applies to infant fruit purées (Cat 1, not Cat 4) but informs the regulatory baseline; California Prop 65 covers cumulative Pb/Cd exposure across produce categories. Awaiting agency-page ingest.
Levers to reduce contamination
The Cat 4 Step 0 lock framework distinguishes lower-contamination row produce/seed rows from contaminated-platform commodity rows (where species or production system carries elevated metal load by characteristic). For this row, the levers below are ordered by impact magnitude per the literature evidence base; sourcing-and-agronomic levers dominate the per-product metal load, with processing-and-formulation levers offering additional reduction.
- Sourcing levers: origin region, supplier specification, soil-Cd or paddy-iAs pre-screening for at-risk commodities.
- Agronomic levers: soil amendments, water management, cultivar selection.
- Processing levers where applicable: washing, peeling, blanching for fresh-cut and frozen formats; refining for derivative products.
- Formulation levers: where the row contains multi-ingredient formats, reducing the platform-commodity fraction.
- Testing/QC levers: lot-level ICP-MS on raw commodity and finished product.
- Regulatory levers.
How standards math uses this page
The percentile arithmetic that informs HMTc Cat 4 thresholds for this row lives on the staff Standards Workbench (data/workbench/standards/root-tuber-vegetables.md, to be generated). This public page reports literature evidence; the workbench applies the Cat 4 methodology (which includes the literature evidence occurrence-data-driven derivation and below-LOQ regulatory-floor fallback per the Step 0 lock) to produce candidate threshold values. The gap between literature evidence and HMTc thresholds is named honestly on the workbench, not hidden.
Historical recalls and enforcement
Cat 4 (produce, nuts, seeds) regulatory enforcement intersects two domains: heavy-metal contamination (the focus of this row) and microbial contamination (FDA recall notices for E. coli/Salmonella/Listeria in fresh produce, a separate concern). FDA Total Diet Study and Pesticide Data Program surveillance reports establish the heavy-metal occurrence baseline (FDA 2022). State-level Cd-in-leafy-greens enforcement has been active in California under Prop 65; the related Mateel Environmental settlement framework has shaped compliance practice. Per CLAUDE.md Part 12, individual brand recall actions are not enumerated here.
