Overview
This page is HMTc Category 5 row 3 from the locked beverage architecture. It exists as a wiki node so evidence, regulatory context, ingredient routing, and future field findings have a stable place to land.
Heavy Metal Index pages are written for several audiences at once. Each entry point below names where to start if you are reading this page with a specific question in mind.
- Brand legal and regulatory affairs
- Cherry-pick attack vectors on non-root vegetable juices typically center on lead and cadmium in leafy-green-derived juices. Source provenance and ingredient-list scrutiny are the defensive core. Compare with Vegetable Juices Root Vegetable Containing for the within-pair sibling. The cited sources at the bottom of this page are the citations list, written to be quoted into a Daubert brief without further editing.
- Retailer quality and compliance
- The Federal / Regulatory Limits vs Field Findings section compares the applicable regulatory cap to cited field evidence on a like-for-like basis, with basis conversion shown when conversion is well-defined and a methodology anchor when speciation differs. The Literature Evidence Summary gives source count and confidence rating per analyte.
- Brand QA and product development
- Use the Lab Result Comparator to position a single lab value inside the cited literature. The comparator positions a single lab value inside the cited literature for non-root vegetable juices.
- Regulators, journalists, and adversarial readers
- Every numeric claim on this page traces to a source page. The Evidence Governance note explains what this page is and is not (literature evidence, not HMT&C certification thresholds).

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) | FDA 2022 Draft — Lead Action Levels for Juice: Federal FDA draft level, not final: 20 ug/kg Pb. Scope: other single-strength juices and juice blends. Basis: single-strength ready-to-drink juice. | No comparable field-finding row has been promoted yet for this beverage category. | Draft context only. Do not present this value as a final federal limit or an HMTc threshold. | FDA 2022 Draft — Lead Action Levels for Juice |
Evidence Handling
Finished-product findings belong on this product page. Ingredient-only findings belong on ingredient pages before they are used for product inference.
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-root vegetable vegetable juice. Values are pulled directly from cited sources without re-aggregation. This page publishes literature evidence only, not certification thresholds.
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 | non-root vegetable (no contributing evidence loaded) | No concentration data loaded for this analyte | Sample-level detection rate not reported | FDA 2022 Draft — Lead Action Levels for Juice: 20 ppb (single-strength ready-to-drink juice) | 0 | data gap | Basis not reported |
| Cd | non-root vegetable (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 |

Levers to reduce contamination
Cat 5 beverage regulatory enforcement covers the FDA Juice HACCP framework (FDA 2004) and 2022 draft Pb-in-juice action levels (FDA 2022) for fruit-juice products, plus EU Reg. 2023/915 Pb-in-juice maximum levels at 30 ppb. The 2019 Mateel Environmental v. Welch Foods California Prop 65 settlement specifically established practical compliance thresholds for grape and other juice products. Tea-and-coffee enforcement is principally California Prop 65 with documented enforcement actions on tea products from Asian importers. Individual brand recall actions are not enumerated here.
How standards math uses this page
This page reports what the peer-reviewed and government literature says about heavy-metal concentrations in this product category; it publishes no certification thresholds of its own. Certification criteria are set separately under the Heavy Metal Tested & Certified program at heavymetaltested.com, which reads this page as its literature baseline. The two are kept apart by design, so this page remains an independent record of the evidence rather than a justification for any threshold.
