Canned Mushrooms

Merged into Category 4, Row 18 (wild and processed-wild mushrooms). Under the v2.1 reorganization (category-4-step0-amendment-1, 2026-06-08), canned wild mushrooms are processed-wild and pool into the contaminated side at wild-mushrooms, carrying the usual canned Sn flag (which cross-references the Category 23 cans/lids tin mechanism). This page is retained as a redirect; its evidence routes to Row 18.

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

Pending. The brand-legal, retailer-compliance, HMTc-internal, and regulator audiences are listed in OPERATING.md Part 2; this section will frame what each is looking for on this page.

Methodology

Pending. This section will state the speciation, basis-preservation, row-fit, and pooling rules from CLAUDE.md Part 6 that govern downstream sections of this page.

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

Hand-curated section. Populated by the synthesis pass as sources contribute.

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

For this product class the dominant lever is the conserving process itself, with marinade-ingredient quality as the second-largest control point and substrate sourcing a distant third. The Pankavec et al. 2019 survey of 100 unit packages of commercial pickled and canned white button mushrooms (Agaricus bisporus) on the Polish market reported overall medians of 0.072 mg/kg dry mass for Pb, 0.040 mg/kg dm for Cd, 0.043 mg/kg dm for tHg, and 0.030 mg/kg dm for tAs across 10 batches from 6 manufacturers, against fresh Agaricus bisporus literature values of approximately 0.54, 0.36, and 0.63 mg/kg dm for Pb, Cd, and tAs respectively per pankavec2019-pickled-mushrooms-poland-minerals. The implied reductions of roughly an order of magnitude for Pb and Cd and roughly tenfold for tAs are attributed to leaching of water-soluble arsenical species and ionic Pb and Cd into the brine and marinade during blanching and pickling, which makes verifying that the blanch and brine steps are present and run to specification the highest-impact processing lever brand-legal teams can audit. Marinade formulation is the second lever and operates in the opposite direction: the inter-producer principal-component analysis attributed batch-level elevations of Li, As, Rb, Sr, Ag, Ba, and Cs to differences in marinade water, vinegar, and salt mineral composition rather than to the mushroom substrate per pankavec2019-pickled-mushrooms-poland-minerals, so a specification on marinade-water mineral content and brine-salt provenance addresses contaminants the substrate did not introduce. Aluminum is the largest non-essential element present in finished product (overall median 2.8 mg/kg dm, per-batch medians 1.4 to 24 mg/kg dm) and is not efficiently leached by pickling; the highest-Al batch was traced to marinade quality per pankavec2019-pickled-mushrooms-poland-minerals, placing Al control on the marinade-input specification rather than on mushroom sourcing. Sourcing and agronomic levers carry less explanatory weight here than for fresh-mushroom product because the conserving process equalizes much of the substrate variability, but they remain relevant for the residual fraction. Testing and QC levers are constrained by the thin literature scope: the present corpus is a single A-tier survey, so brand-level surveillance would require additional published surveys or private brand-intelligence data outside this wiki’s scope per Part 12. Packaging and storage levers are not differentiated by the available evidence; the Pankavec study sampled 80 glass jars and 20 cans without isolating package-format effects on contaminant migration.

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 public-record recall or enforcement action specific to canned or pickled white button mushrooms has been routed to this page from the current corpus. The single contributing surveillance study reported that all 10 sampled batches sat well below the EU maximum levels for cultivated Agaricus bisporus under Commission Regulation (EC) No 629/2008 amending eu-1881-2006-contaminants-superseded, which set 0.30 mg/kg fresh weight for Pb and 0.20 mg/kg fresh weight for Cd (roughly 3.0 and 2.0 mg/kg dry mass under a 90% moisture assumption); overall medians in the conserved product were 0.072 and 0.040 mg/kg dm respectively per pankavec2019-pickled-mushrooms-poland-minerals n=100. The 2016 sampling pre-dates the consolidation of EU contaminants limits into Commission Regulation (EU) 2023/915, which now governs this product class in the EU but maintains the same cultivated-Agaricus thresholds. This section will be repopulated as additional sources route here or as the synthesis pass surfaces enforcement actions from FDA, USDA FSIS, EU RASFF, or comparable agency feeds. Per Part 12, any future entries will be framed as regulatory events rather than brand rankings.
