Evidence summary
Evidence summary
The table below summarizes what the peer-reviewed and government literature cited on this page reports for heavy-metal concentrations in Rice snacks/crackers. 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 | Rice snacks/crackers (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 | Rice snacks/crackers (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 |
| iAs | Rice snacks/crackers (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 | Rice snacks/crackers (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 |

How standards math uses this page
HMT&C certification thresholds for this row are developed under the certification program at heavymetalcertified.com, not on this page. The row-standard for this row is an aggregate computed from the contributing source pool in the row’s native finished-product basis; it is not a per-source decoration of any single value cited on this page. This public page reports literature evidence only.
Historical recalls and enforcement
Public regulatory events for this row, such as recalls and import alerts, will be listed here as they are catalogued.
Methodology
This page reports what the cited sources say about heavy-metal concentrations in rice snacks/crackers. Speciation is non-substitutable (iAs vs tAs, MeHg vs tHg, Cr-VI vs total Cr). Basis is preserved (finished-product as sold unless the source specifies otherwise; see each row for the basis label). Non-detect handling follows each source’s reporting convention. Pooling is 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 heavymetalcertified.com, not on this page; this public page reports literature evidence only.
The applicable regulatory jurisdictions for this row are: FDA, EU, Codex.
