Norway lobsters, frozen, dried, salted or in brine

1. Scope and Applicability

This PCR supports foreground data packages for raw Norway lobster (Nephrops norvegicus), in shell or not, preserved by one declared route: frozen, dried, salted, or in brine. It covers processor-gate operations from receipt of eligible live, fresh, or chilled raw material through preparation, the declared preservation route, packaging, and any on-site storage before dispatch. Capture, aquaculture, landing and inbound transport are upstream dataset inputs; distribution, retail, cooking, consumption and end-of-life are outside the foreground boundary.

Cooked, smoked, canned, or otherwise processed Norway lobster; other lobster species; and route mixtures that cannot be separated into route-specific inventories are excluded. The foreground data package shall not average frozen, dried, salted and brined production unless each route is separately modelled and the aggregation purpose and weighting records are disclosed.

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	Normalize all inventory results to 1 kg net product mass at processor-gate dispatch.

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
allocation_route_separation	Multiple preservation routes or materially different presentations	Avoid allocation by subdividing route, line, batch and presentation inventories. Do not allocate a combined multi-route inventory to the reference product when route-specific records can be obtained.	eu-pef-2021-2279
allocation_co_products	Marketed shell, meat, residual or other co-product	First seek process subdivision or a documented physical causal relationship. If this is not feasible, use an economic relationship based on contemporaneous net revenue and report prices, period and sensitivity; do not assign zero burden solely because an output is secondary.	eu-pef-2021-2279
allocation_shared_resources	Shared water, energy, packaging equipment and storage	Prefer direct metering. Otherwise use a documented physical driver such as equipment time and load, line throughput, occupied cold-store capacity and storage duration; disclose the driver and test whether it materially changes results.	eu-pef-2021-2279
allocation_waste_treatment	Rejects, wastewater, spent brine, packaging scrap and refrigerant losses	Do not treat waste as a co-product unless a documented market function exists. Include in-boundary collection or treatment operations and emissions, and disclose any downstream waste-treatment dataset and recycling or recovery convention.	eu-pef-2021-2279

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
dq_identity_traceability	Raw input and reference product	Demonstrate Nephrops norvegicus identity, lot traceability, route, raw state, presentation and processor-gate net-mass basis.	Supplier/landing record, species identification, lot record, label and release record; unsd-cpc-3-0; codex-cxs-95-1981
dq_temporal_geographic_technology	All foreground data	Use data representative of the declared sites, technologies, seasonal production and reporting period; disclose gaps, outsourced operations and substitutions.	Site list, equipment register, production calendar and representativeness assessment; eu-pef-2021-2279
dq_completeness_reconciliation	Mass, water, energy, packaging, waste and refrigerant records	Reconcile inputs and outputs at route and reporting-period level. Investigate rather than silently close material gaps; report data coverage and estimation share.	Mass/water/energy balances, invoices, meter coverage and gap log; eu-pef-2021-2279
dq_measurement_quality	Metered and weighed records	Retain units, calibration status, sampling frequency, conversion factors and responsible data owner.	Calibration certificates, raw exports, scale logs and calculation workbook
dq_food_safety_records	All declared routes	Retain validated route-specific controls, monitoring, corrective action and release evidence. Frozen product records shall demonstrate the applicable freezing and storage condition.	HACCP and release records; codex-cxc-52-2003; codex-cxs-95-1981
dq_provisional_values	Missing foreground quantities	Do not introduce a numerical default or QA range without reviewed evidence. Any temporary estimate shall be labelled reasoned_estimate, documented as replaceable and reported in the data-quality disclosure.	Data-gap register and reviewer decision

9. Validation Rules

rule_id	Applies to	Rule	source_ids
validate_reference_identity	Reference flow	Fail if the product-flow UUID, Mass property UUID, unit-group UUID, 1 kg amount, species, raw state, route, presentation or net-mass qualifiers are missing or inconsistent.	unsd-cpc-3-0; codex-cxs-95-1981
validate_single_route	Process map and inventory	Fail if no preservation route is declared, more than one route is combined without separate inventories, or a route-specific input is applied unconditionally to another route.	unsd-cpc-3-0; codex-cxc-52-2003
validate_mass_and_units	Lot and normalized inventory	Fail if reference mass includes packaging, free brine or external glaze; if mass states are mixed without conversion; or if lot inputs, products and residuals lack a documented reconciliation.	codex-cxs-95-1981
validate_route_controls	Preservation and storage	Fail if applicable food-safety release records are absent. For frozen product, fail if the thermal centre did not reach -18 °C or colder after stabilization or storage was not maintained at -18 °C or colder.	codex-cxc-52-2003; codex-cxs-95-1981
validate_allocation	Co-products and shared resources	Fail if avoidable route aggregation remains, an allocation driver lacks records, a marketed co-product is assigned zero burden without justification, or waste conventions are undisclosed.	eu-pef-2021-2279
validate_data_completeness	Foreground package	Fail if required protocols omit route/site/period coverage, if material data gaps are hidden, or if any numerical temporary value is not labelled reasoned_estimate and disclosed as replaceable.	eu-pef-2021-2279

10. Published Dataset Profile

Field	Value
dataset_role	Foreground product-system dataset for preserved raw Norway lobster at the processor gate
