Rice finding 2094
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) · 14 rice samples (retail products); n from Summary Table rice rows.
Selected finding and reference
14 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
Instant
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.
