Fish meat, whether or not minced, frozen

1. Scope and Applicability

This PCR covers the foreground manufacture of frozen fish meat, whether minced or not, from received fish, fish portions, or fish flesh through preparation, optional mincing, freezing, optional glazing, packaging, and frozen storage to the declared processing-facility gate. The data producer shall declare species, source production system, received form and temperature state, whether the product is minced, whether glaze is present, packaging format, geography, technology, and the frozen-storage period represented.

It excludes frozen fish fillets classified separately, whole frozen fish, fish livers and roes, surimi and formulated fish preparations, cooked, smoked, dried, salted, or otherwise preserved fish, and crustacean, mollusc, or other aquatic-invertebrate products. Fishing or aquaculture, landing, and manufacture of received upstream fish inputs are represented by upstream datasets rather than silently absorbed into this foreground process.

validate_reference_identity	reference_flow	Require product-flow UUID bbae8c72-d732-4f53-bdd5-aff8a0f39d48, Mass UUID 93a60a56-a3c8-11da-a746-0800200b9a66, unit-group UUID 93a60a57-a4c8-11da-a746-0800200c9a66, unit kg, and exactly 1 kg net fish-meat reference mass.
validate_scope_qualifiers	dataset_identity	Reject guidance as incomplete when species/origin, upstream dataset, product form, minced status, glaze, packaging scope, freezing technology, storage regime and duration, geography, or data period are missing.	cpc-v3-21223; codex-cxc-52-2003
validate_process_coverage	process_inventory	Require every required process and each applicable conditional process, including the complete on-site frozen chain, or a documented zero/not-applicable statement supported by facility evidence.	codex-cxc-52-2003
validate_mass_reconciliation	mass_balance	Require lot- or period-consistent reconciliation of received input, net product, glaze, co-products, residues, rejects, wastewater-associated material, and inventory change; flag unexplained residuals for review.
validate_allocation	multifunctionality	Require allocation avoidance evidence or the selected physical/economic method, factors, co-product status, price period when relevant, and sensitivity disclosure.	eu-pef-2021-2279
validate_cold_chain_quality	food_safety_and_quality	Require linked control records for freezing, storage, package integrity, excursions, and corrective actions under applicable requirements; do not infer compliance from an average temperature alone.	codex-cxc-52-2003; codex-cxs-190-1995 when applicable
validate_data_quality	foreground_dataset	Require temporal, technological, geographical, completeness, traceability, calibration, and uncertainty/estimate disclosures, including identification of every provisional range used.	eu-pef-2021-2279

10. Published Dataset Profile

Field	Value
dataset_role	Foreground production dataset for frozen fish-meat manufacturing at the processing-facility gate
downstream_use	secondary_dataset; background_dataset
allowed_use	LCA of declared frozen fish meat when species/origin, upstream production, product form, facility technology, glaze, packaging, storage duration, geography, time period, and allocation are representative
excluded_use	Direct representation of fishing or aquaculture, whole frozen fish, separately classified frozen fillets, livers or roes, surimi/formulated products, other preservation routes, downstream distribution, retail, cooking, consumption, or end-of-life without added datasets
required_metadata	PCR id and version context; product-flow UUID; species/origin; upstream datasets; minced status; product and packaging form; glaze fraction; additives; included operations; freezing and refrigeration technology; storage regime/duration; geography; data period; allocation method; co-product/waste status; cut-offs/proxies; data owner and review status
required_quality_disclosure	Source-to-row traceability; measurement and calculation methods; calibration and reconciliation; temporal, technological, and geographical representativeness; mass balance; food-safety control evidence; allocation sensitivity; missing data; provisional estimates; uncertainty and limitations
update_trigger	Material change in fish source or species mix, received form, product specification, mincing/freezing/glazing technology, refrigerant, energy supply, packaging, storage duration, allocation/co-product route, regulation, facility configuration, or representative data period
