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.
References
Works cited in this page’s text, in first-appearance order. This is not the full corpus for this page; it is only what the prose above draws on. The complete set of sources is listed under Sources below. Each title links to its source record, which carries the ingest receipt, the extracted values, and the file hash of the document it was built from.

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 Mineral Constituents of Conserved White Button Mushrooms: Similarities and Differences. 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 Mineral Constituents of Conserved White Button Mushrooms: Similarities and Differences, 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 Mineral Constituents of Conserved White Button Mushrooms: Similarities and Differences, 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
This page reports what the peer-reviewed and government literature says about heavy-metal concentrations in this product category; it publishes no certification thresholds of its own. Certification criteria are set separately under the Heavy Metal Tested & Certified program at heavymetaltested.com, which reads this page as its literature baseline. The two are kept apart by design, so this page remains an independent record of the evidence rather than a justification for any threshold.
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 Commission Regulation (EC) No 1881/2006 setting maximum levels for certain contaminants in foodstuffs, 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 Mineral Constituents of Conserved White Button Mushrooms: Similarities and Differences 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.
