Rice finding 2100
Source evidence and comparison details for the Rice profile.
Rice grain as sold (category includes white, brown, parboiled, instant/precooked as labelled) · Inorganic arsenic (iAs) · 91 rice samples (retail products); n from Summary Table rice rows.
Selected finding and reference
91 rice samples (retail products); n from Summary Table rice rows. Basis: dry weight (RACC 45 g dry rice per serving).
Category average computed by FDA using all iAs values; for samples not speciated (tAs below speciation threshold) half of tAs was used, and half the LOD where tAs<LOD (Summary Table footnote 1). Range endpoints may include such proxies.
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
Collection date unreported
No year-by-year sample register is reconstructed from this summary.
Geographic scope
White, medium grain
Rice variety or type within one study.
Sampling, analysis and reporting limits
Total arsenic and arsenic speciation (AsIII+AsV as iAs, DMA, MMA); instrument not described in this document. Speciation only when total As exceeded a threshold..
Category average computed by FDA using all iAs values; for samples not speciated (tAs below speciation threshold) half of tAs was used, and half the LOD where tAs<LOD (Summary Table footnote 1). Range endpoints may include such proxies.
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.
