Style-specific measurement	For solid cuts, report each required dimension and the in-size fraction; for minced material, report particle distribution; for moulded puree or portions, report unit mass and refining grade separately.	Apply the measurement method to the selected physical style; do not use a portion weight as a solid-cut dimension.

02 / Physicochemical & Residue Controls

Parameter	Specification / reference	Verification & order basis
Codex reference: mineral impurities	≤0.2 % m/mExternal reference Codex	Residue insoluble in hydrochloric acid after ashing; use relevant CXS 234-1999 method. No fixed sample mass stated in §3.3.6. Only a single-species quick-frozen edible-fungus SKU meeting CXS 38 §2.1.12: cleaned, washed and blanched before freezing. Confirm botanical species and blanching route; unblanched supply is outside this definition.
Prepared yield / water release	Evaluate thawed or cooked yield under one agreed preparation protocol; differentiate natural exudate from added water or loose ice.	Report initial mass, preparation conditions, drained edible mass and yield percentage.
Pesticide residue schedule	Named active ingredients and commodity-specific limits are selected for the destination market. EU source	Link farm spray history, laboratory LOQ and batch result to the destination MRL. EU database is one market reference; apply the actual destination rule.
Lead, cadmium and other contaminants	Apply the limit for the exact commodity and processed form in the destination market. EU source	State analyte, preparation basis, method, LOQ and lot result. Do not transfer a fresh-commodity limit to a processed form without the required assessment.

03 / Microbiological Criteria

Parameter	Specification / reference	Verification & order basis
Hygiene-indicator panel	Select aerobic count and relevant Enterobacteriaceae, coliform or E. coli indicators for the declared process and intended use. Codex	Report each quantitative result in CFU/g, method/reporting limit, sample plan and lot identity.
Pathogen acceptance programme	Define Salmonella and Listeria criteria when applicable to the destination, ready-to-eat status and buyer programme. Codex	State analytical portion, sample-unit plan, method and detected/not-detected reporting; identify the treatment and release basis.
Yeast & mould enumeration	Select separate yeast and mould criteria for the ordered grade and process; assess storage stability with the applicable product data. Codex	Report yeast and mould separately in CFU/g using validated matrix-specific methods.
Acceptance schedule	Select the test panel and limits by intended use (ready-to-eat or further processing), product form and destination. EU source	State organism, analytical method, sample mass and n/c plan; report actual lot results. A universal APC, coliform, Salmonella or Listeria limit is not assigned to every frozen product.

Shelf Life	24 monthsPublished reference	Verify unopened-pack validation, declared storage condition and production/best-before coding.
Declared net contents	Verify each selected pack format against the artwork and applicable quantity-control rule. Codex	Calibrated checkweigher or scale; defined sample and tare.
Shelf-life basis	The labelled period applies only to its validated pack and continuous stated storage condition. Codex	Review stability study or approved shelf-life file and production-date code.

06 / Process Controls

Parameter	Specification / reference	Verification & order basis
Processing Method	Sorting, trimming, washing, slicing or cutting, IQF freezing, metal detection and packingPublished reference	Check the approved product flow, line settings and identified production record; validate numerical critical limits within the site HACCP plan.
Raw-material preparation checks	State cap-to-stem proportion and cross-cut coin versus lengthwise plank; measure each independently.	Verify the selected product flow and the relevant trimming, sorting and pretreatment record.
CCP designation	Use the site-approved HACCP plan to identify true CCPs and their validated critical limits. Codex	Check hazard analysis, monitoring, deviation and corrective-action records. A quality-control step is not automatically a CCP.

07 / Ingredients, Additives & Allergens

Parameter	Specification / reference	Verification & order basis
Added glaze / coating declaration	Declare any intentionally added water glaze, syrup, oil or coating and the measurement basis; loose ice is assessed separately.	Verify formula/addition records; agree a deglazing or coating test and net-content basis where applicable.
Ingredient statement	List every ingredient and its declared role for the selected SKU; verify any added sugar, oil, coating, seasoning or glazing medium.	Approved formula and supplier declarations.
