Fish livers and roes, frozen

1. Scope and Applicability

This PCR governs foreground data packages for edible fish livers, fish roes, or declared mixtures of the two that are separated, cleaned or graded as applicable, frozen, optionally glazed, packaged, and delivered at the frozen-product cold-store gate. It applies to shore-based and vessel-based processing when the included operations and starting condition are declared.

It excludes fresh or chilled livers and roes; dried, smoked, salted, or brined products; cooked, canned, fermented, seasoned, or otherwise prepared products; non-fish aquatic animal organs; non-food grades; and products in which fish liver or roe is only an ingredient. Fishing or aquaculture, landing, and upstream production of incoming fish or separately purchased organs are represented by linked upstream datasets rather than recreated inside the foreground process, unless the study explicitly expands the boundary.

The foreground data package shall identify species or species group, liver/roe/mixed state, whole-fish versus separated-organ starting condition, wild-caught or aquaculture origin when known, product form, freezing technology, glaze share, packaging format, storage duration and temperature, site or vessel, geography, and reporting period.

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
reference_mass	Reference product	Mass 93a60a56-a3c8-11da-a746-0800200b9a66	kg	Report exactly 1 kg net edible frozen product; exclude primary, secondary, and transport packaging and subtract separately declared glaze ice from gross weighed mass.

water_mass_conversion	Metered water	Mass 93a60a56-a3c8-11da-a746-0800200b9a66	kg	Prefer measured mass; when volume is recorded, retain measured volume, density assumption, temperature if material, and the conversion calculation.
energy_reporting	Electricity and thermal energy	Energy	kWh and MJ	Preserve metered carrier and unit, convert with a declared factor, and do not combine electricity, fuel, and recovered energy into one undifferentiated total.
temperature_reporting	Freezing and frozen storage	Temperature	°C	Record product thermal-centre temperature after thermal stabilization where available and the cold-store temperature record; do not infer temperature from equipment set-point alone.
glaze_accounting	Glazed product	Mass 93a60a56-a3c8-11da-a746-0800200b9a66	kg	Measure or calculate glaze ice separately and disclose the method; glaze is not part of the 1 kg net edible reference amount.

alloc_economic	Joint outputs without a defensible causal physical relation	Use contemporaneous economic value at the allocation point, disclose prices, currency, period, quantities, treatment of zero-value outputs, and uncertainty, and test a mass-based sensitivity case.	eu-pef-2021-2279
alloc_upstream	Linked fish-production datasets	Preserve the allocation already embedded in accepted upstream datasets and disclose it; do not allocate the same upstream burden again in the foreground model.	eu-pef-2021-2279
alloc_recycling_treatment	Packaging recycling, residue recovery, and waste treatment	Apply the declared downstream treatment or recycling method consistently, disclose credits or substitutions, and prevent double counting between product, waste, and avoided-product claims.	eu-pef-2021-2279

val_scope	Product identity	Reject or flag products that are fresh/chilled, dried, smoked, salted, brined, cooked, canned, fermented, seasoned, non-fish, non-food, or preparations in which liver or roe is only an ingredient.	unsd-cpc-3-0-21226
val_qualifiers	Dataset metadata	Fail completeness when any required qualifier is absent or when gross, net, packaging, and glaze mass conventions are ambiguous.
val_freezing	Freezing lot	Require evidence that the product thermal centre reached -18 °C or lower after thermal stabilization; retain nonconformance and corrective-action records.	codex-cxc-52-2003
val_frozen_storage	Cold store	Require a frozen-storage temperature record demonstrating maintenance at -18 °C or the stricter declared specification; flag excursions and their disposition.	codex-cxc-52-2003
val_process_coverage	Foreground inventory	Require all three process-map rows and all applicable inventory rows; a missing flow must have a documented zero, not-applicable, or excluded-with-justification decision.
val_mass_balance	Process and system mass flows	Require lot- and period-compatible mass reconciliation; report closure residual and investigate unresolved differences before dataset release.	eu-pef-2021-2279
val_allocation	Multi-output operations	Require evidence that allocation was avoided where possible; otherwise require the causal physical or economic basis, complete output set, factor sum, allocation point, and sensitivity disclosure.	eu-pef-2021-2279
val_refrigerant	Refrigeration systems	Require substance identity and mass-balance records when refrigerant additions or losses occur; reject an unidentified generic refrigerant emission.
val_reasoned_ranges	Provisional QA screens	Treat values outside reasoned-estimate ranges as review findings, not automatic replacements; never substitute a midpoint for missing foreground data, and disclose every retained estimate.
val_data_quality	Published data package	Require temporal, technological, geographic, completeness, measurement, food-safety, proxy, and uncertainty evidence defined in section 8; mark validation inconclusive when required records are unavailable.	eu-pef-2021-2279; codex-cxc-52-2003

10. Published Dataset Profile

Field	Value
