Rice finding 137
Source evidence and comparison details for the Rice profile.
US market rice, mixed forms (polished, unpolished/brown, parboiled, instant, iron-enriched; medium, long, extra-long, aromatic) · Total arsenic (tAs) · 27 retail rice samples (packs).
Selected finding and reference
27 retail rice samples (packs). Basis: dry weight.
All samples above LOD (lowest value 0.06 µg/g vs LOD 0.019 µg/g); no non-detects reported
HMI baseline position
Limited data: The source reports a range, percentile or extreme value; only a mean, median or sample result can be positioned against a reference. Missing evidence never means low contamination.
The source reports a range, percentile or extreme value; only a mean, median or sample result can be positioned against a reference.
Reference version and interpretation
Frozen evidence selection: 2026-10-22. Method: hmi-pooled-reference-v2.
No admitted reference
The reference is computed by HMI from admitted evidence, not copied from a study baseline. It describes the evidence currently in this scope; it is not a worldwide or current-lot benchmark. Source, year and region filters do not change it. Different HMI scopes are not one common ranking.
Collection period
2005
No year-by-year sample register is reconstructed from this summary.
Geographic scope
California
Reported growing area.
Sampling, analysis and reporting limits
Agilent 7500c ORS-ICP-MS (total elements); no As speciation.
All samples above LOD (lowest value 0.06 µg/g vs LOD 0.019 µg/g); no non-detects reported
Shared samples and study overlap
Subgroup rows, statistics of the same subgroup and the study total share samples; they are not independent results.
Each table row describes a food/analyte result. Repeated rows do not add independent samples or datasets. No cross-study trend is calculated in this comparison mode.
Reported values, conversion and source locator
| Source statistic | Original result | Displayed unit conversion |

No moisture, cooking-yield or species conversion is applied to the original finding above. Any basis conversion used for its HMI comparison is stated separately with the numerical target.
