Fish livers and roes, fresh or chilled

1. Scope and Applicability

This PCR applies to foreground data packages for edible fish livers, fish roes, or a declared mixture of the two that is kept fresh or chilled and supplied as net product mass at the declared facility gate. It covers receipt, separation from fish or viscera when performed by the reporting facility, trimming, washing when used, sorting or grading, chilling, cold storage, packing, and dispatch preparation.

The dataset shall declare species or species group, wild-caught or aquaculture origin, liver/roe product part, incoming material form, whether separation occurs in the foreground, preservation state, added ingredients, packaging configuration, cold-storage duration, temperature-control method, and facility-gate geography. Whole fish, fish meat and fillets, frozen livers or roes, salted, smoked, cooked, canned, fermented or otherwise preserved products, prepared caviar, fish oils, liver oils, feed products, and non-food products are outside this PCR.

validate_boundary_processes	Process coverage	Fail when receipt/inspection, applicable separation, preparation, chilling/cold storage, packing, wastewater/residual handling or required upstream dataset linkage is missing without a documented scope reason.	codex-cxc-52-2003; eu-pef-2021-2279
validate_cold_chain_records	Cold chain	Fail when storage duration, temperature-control method, energy or ice route, or applicable refrigerant records are absent for foreground-controlled chilling and storage.	codex-cxc-52-2003
validate_mass_balance	Material flows	Fail when product, co-product, residual, waste and stock-change records cannot be reconciled to incoming material on a consistent wet-mass basis or the unexplained difference is not investigated and disclosed.	eu-pef-2021-2279
validate_allocation	Multifunctionality	Fail when a multifunctional separation or shared operation lacks avoided-allocation analysis, complete output inventory, selected allocation rationale, factors and sensitivity where material.	eu-pef-2021-2279
validate_data_quality	Dataset production	Fail when temporal, geographic, technological, completeness, calibration or source-traceability evidence required by section 8 is missing or material gaps are undisclosed.	eu-pef-2021-2279
validate_reasoned_estimates	Provisional ranges	Flag each retained reasoned_estimate for reviewer replacement; it shall not be represented as an industry benchmark or source-backed allowed range.

10. Published Dataset Profile

Field	Value
dataset_role	Foreground production data package that may be published after review as a secondary_dataset and/or background_dataset
downstream_use	Construction of product flows, unit processes, aggregated processes and lifecyclemodel projections for fresh or chilled fish liver/roe supply

excluded_use	Frozen, salted, smoked, cooked, canned, fermented, prepared-caviar, oil, whole-fish, fish-meat, retail, cooking or consumption modelling without an explicit scope extension
required_metadata	PCR id and version; species/origin; liver/roe form; incoming condition; separation location; facility and geography; technology; reporting period; net-mass basis; cold-storage duration; temperature-control route; packaging; upstream datasets; allocation; cut-offs; data sources
required_quality_disclosure	Protocol coverage; measured versus calculated values; unresolved UUIDs; retained reasoned estimates; mass-balance closure; data gaps; allocation sensitivity; cold-chain records; representativeness and uncertainty limitations
update_trigger	Material change in species mix, origin, incoming form, separation point, process route, refrigeration system, storage duration, packaging, allocation, regulation, source evidence or foreground data quality
