Infant Solid Foods Mixed
Provisional scaffold. This page was created automatically on 2026-05-20 so that an ingested source could route to it. The HMTc taxonomy row, clean/contaminated pairing, primary metals of concern, and detailed scope have not yet been locked. Content below is minimal until a synthesis pass or taxonomy review consolidates the literature for this product class.
Reason: heal-gaps: routing_unresolved entry from source unknown2016-risk-arsenic-rice-cereal declared product/infant-solid-foods-mixed, no close-slug match
Triggering source: unknown2016-risk-arsenic-rice-cereal
Literature scope
The literature corpus for this product class is currently thin. Sources route here as ingest proceeds; once enough sources accumulate, the synthesis pass will populate the Literature Evidence Summary, Source Evidence Inventory, and downstream sections per CLAUDE.md Part 6.
Sources
Auto-generated from source-page frontmatter. The “Used on this page for” column is populated by the orchestrator’s POPULATE-SOURCE-LEGEND action; pending entries appear as *[awaiting synthesis]*.

Who this page is for
This provisional page is for mixed infant solid foods that do not yet resolve into locked rice-containing, non-rice, puree, cereal, snack, or meal rows. Brand legal and retailer readers should treat it as an early-routing page for exposure and risk-assessment evidence. HMTc staff should use it to keep broad infant-solid-food arsenic evidence visible while assigning values to narrower rows before any benchmark pooling.
Methodology
Mixed solid-food evidence is admitted here only as context until the recipe driver and product basis are clear. open2017-open-infants-dietary-arsenic contributes urinary arsenic speciation during transition to solid foods, with rice cereal, fruit, and vegetables as dietary correlates. unknown2016-risk-arsenic-rice-cereal contributes modeled US infant and toddler inorganic-arsenic exposure using FDA rice-cereal survey data and dietary-intake assumptions. These sources support the mixed-solid-food exposure pathway, but concentration values should be routed to infant rice cereal or another locked row when the driver is identifiable.
Literature Evidence Summary
Pending: regenerated by tools/evidence/apply-product-hmtc-evidence-summaries.mjs once sources route and the pooling engine emits aggregate rows for this product category.
Source Evidence Inventory
open2017-open-infants-dietary-arsenic followed 15 US infants through the 4- to 6-month transition to solid foods and reported a 3.8-fold rise in summed urinary arsenic species, with rice cereal most strongly correlated with urinary inorganic arsenic. unknown2016-risk-arsenic-rice-cereal modeled US infant and toddler inorganic-arsenic exposure using one million Monte Carlo iterations, with rice cereal accounting for about 55% of total inorganic-arsenic exposure in infants 4-24 months. Together, they make this page useful for mixed-solid-food exposure context while also showing that rice-containing products need separate row-level handling.
Broad Product Context: Author-Scope Index
Pending: regenerated by tools/evidence/apply-product-broad-context.mjs once broad-scope sources route to this page.
Federal/Regulatory Limits vs Field Findings
Pending: regenerated by tools/apply-product-crosswalk-sections.mjs once applicable_regulations are identified and field-finding evidence is pooled.
Levers to reduce contamination
The clearest lever is formulation control around rice and rice-derived ingredients, because both contributing sources identify rice cereal or rice-based foods as major inorganic-arsenic drivers during the early solid-food window. Mixed meals should preserve recipe-level row fit, including whether rice flour, rice cereal, or rice starch is present, before values are pooled with non-rice mixed meals. Finished-product testing should keep age band, product basis, and serving form visible because the highest modeled exposure in the risk assessment was for 4-6-month infants.
How standards math uses this page
The percentile arithmetic that informs HMTc thresholds for this product category lives on the staff Standards Workbench (data/workbench/standards/<this-slug>.md). This public page reports literature evidence; the workbench applies the methodology in CLAUDE.md Part 19. The gap between literature evidence and HMTc thresholds is named honestly on the workbench, not hidden.
Historical recalls and enforcement
No recall or enforcement synthesis has been promoted for this provisional mixed-solid-food page. The current sources provide exposure and risk-assessment context for inorganic arsenic, especially rice cereal, but do not report a public enforcement event for a mixed solid-food product. Regulatory context should be handled on the relevant locked row, particularly infant rice cereal, when scope is clear.
