Plant Milks (Almond, Oat, Coconut, Other Non-Soy/Non-Rice)

This page is HMTc Category 5 row 5. It remains a clean-benchmark candidate, but the current evidence is not strong enough to use it as a clean comparator without more occurrence extraction.

Who this page is for

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-soy non-rice plant milks (almond, oat, coconut, cashew, etc.) typically center on cadmium and lead with high inter-variety variance. Source provenance and varietal disclosure are the defensive core. Compare with Plant Milks Rice Based 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-soy non-rice plant milks.
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).
HMT&C staff (internal)
The threshold-selection arithmetic (percentile statistics, clean / dirty subcategory designation, CC eligibility) lives on the staff workbench snapshot at plant-milks-non-soy-non-rice, not on this public page.

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.

Occurrence Evidence

marques2021-trace-elements-milks-plant-based-drinks measured almond, oat, rice, and soy drinks from the Spanish retail market. It supports routing and shows why non-soy/non-rice plant milks cannot simply be assumed clean, but it is not enough to populate thresholds.

Ingredient Handling

Finished oat or almond beverage values belong on this product row. Ingredient-only almond, oat, coconut, or plant-milk values belong on the linked ingredient pages if those sources are later promoted.

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-soy (cow milk-based) product. 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.
