Other meat of mammals, frozen

1. Scope and Applicability

This candidate PCR covers one foreground data-package instance within CPC 3.0 21139. The instance is farmed red deer (Cervus elaphus) meat, UNECE cut 9237 inner part of the leg, long-cut, boneless, vacuum packed in a polyamide/polyethylene pouch, packed in a corrugated cardboard carton with a polypropylene label, quick-frozen in a forced-air blast freezer using an R717 ammonia refrigeration system, stored frozen, and delivered at the facility loading dock with a thermal-centre product temperature of -18 deg C or colder.

CPC 21139 is broader than this instance. No authoritative CPC-wide species share was found. Red deer is therefore a mandatory data-package instance gate, not a claimed default market share. A dataset for another species, cut, bone state, freezing technology, refrigerant system, packaging configuration, or delivery-temperature specification requires a separately reviewed instance and must not be averaged with this one.

The foreground boundary starts with receipt of the specified chilled boneless red deer cut and ends with net frozen meat at the facility loading dock. It includes receiving, vacuum packaging, forced-air blast quick freezing, frozen storage, sanitation, on-site aerobic wastewater treatment, and dispatch. The upstream cut-specific dataset must include deer production, slaughter, dressing, chilling, boning, cut preparation, and their allocation. Distribution after the loading dock, retail, cooking, consumption, and end-of-life of consumer packaging are excluded. Edible offal, fresh or chilled meat, bone-in meat, comminuted meat, mixed-species production, cryogenic freezing, plate freezing, and still-air freezing are excluded.

The selected freezer uses electricity and R717 ammonia. Hot-gas defrost recirculates R717 inside the refrigeration system and is not a boundary-crossing heat-carrier flow. No fuel, steam, ice, transport service, or other thermal carrier may be added unless the instance gate is revised and the added flow is collected as its own atomic row.

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
reference_net_mass	reference product	Mass	kg	Report 1,000 kg net edible meat; exclude pouch, label, carton, pallet, ice, frost, glaze, and free liquid from reference mass.
mass_balance_basis	all meat-bearing processes	Mass	kg	Use calibrated receipt, transfer, reject, and dispatch masses on the same lot basis; calculated transfers must preserve incoming mass = outgoing meat + meat rejects + measured mass change, with any unresolved difference disclosed.
packaging_mass_basis	each packaging material	Mass	kg	Measure polyamide/polyethylene pouches, polypropylene labels, and corrugated cardboard cartons separately; do not report a combined packaging mass.
electricity_unit	each electricity row	Energy	kWh	Preserve submetered kWh by process; if a shared meter is used, apply and disclose one causal allocation calculation rather than combining process electricity rows.
refrigerant_mass_balance	each R717 refrigeration process	Mass	kg	For each equipment group and period, calculate R717 loss as opening charge + make-up - closing charge - documented recovery; do not combine blast-freezer and storage-system leakage.
water_volume_mass	sanitation water and wastewater	Volume and mass	m3 and kg	Record potable water and wastewater volume in m3 and pollutant loads in kg; calculate pollutant load from matched flow volume and concentration records.
temperature_basis	freezing, storage, and dispatch	Temperature	deg C	Record calibrated product thermal-centre temperatures for freezer completion and dispatch and continuous or logged storage-air temperatures; the instance gate is <= -18 deg C for product thermal-centre temperature.

5. System Boundary

The foreground system is a gate-to-gate frozen-meat finishing operation. Product identity is inherited from a cut-specific upstream dataset and maintained through lot-level mass and traceability records.

Boundary Abstraction

Field	Value
declared_starting_condition	Chilled, food-safe, boneless farmed red deer (Cervus elaphus) UNECE 9237 inner part of the leg, long-cut, received as an identified lot with measured net mass and temperature
starting_condition_role	Upstream product input to the frozen-meat finishing foreground system
product_classification_scope	Narrower data-package instance within CPC 3.0 21139; it is not a CPC-wide species or technology mix
recursive_input_rule	If any frozen meat that itself satisfies this PCR enters the foreground system, record it as a separate product input with an upstream dataset and subtract it from newly produced output; never recursively re-create or silently merge it with the reference output.
upstream_dataset_requirement	Use a cut-specific dataset covering farmed red deer production, slaughter, dressing, chilling, boning, UNECE 9237 cut preparation, and allocation to the received boneless cut; a live-animal, generic carcass, generic venison, or mixed-species dataset is not sufficient.
disclosure	Declare the exact species, farmed status, cut code and description, bone state, origin, upstream dataset, facility, production dates, freezing equipment, R717 equipment group, packaging specification, storage duration, dispatch temperature, and every deviation from the boundary.

rule_id	Applies to	Rule	source_ids
boundary_instance_gate	all foreground packages	Include only the declared red-deer UNECE 9237 boneless forced-air/R717 configuration; do not average another species, cut, bone state, freezing technology, refrigeration system, packaging configuration, or temperature specification.	unstats-cpc-3-2025; unece-deer-meat-2013; dinz-farmed-venison; wiklund-et-al-2014-venison
boundary_upstream_cut	chilled meat input	Require the upstream cut-specific dataset through chilled boneless-cut preparation and keep all upstream burdens outside the finishing foreground inventory to avoid double counting.	unece-deer-meat-2013; fao-who-cxc-58-2005
boundary_quick_freezing	blast freezing and cold chain	Include measured freezing and storage operations until dispatch; quick freezing is complete only when product thermal-centre temperature reaches <= -18 deg C, and the cold chain must preserve that condition subject only to documented legal tolerances.	fao-who-cxc-8-1976; fao-meat-cold-store-manual
boundary_on_site_wastewater	sanitation wastewater	Include the declared on-site aerobic treatment and direct discharge; another wastewater route requires a separately declared scenario and must not be averaged into this route.	fao-who-cxc-58-2005

7. Allocation and Co-product Handling

The foreground finishing route has one intended meat product and no co-product. Packaging rejects, rejected meat, wastewater, and sludge remain waste flows unless a documented downstream recovery contract establishes otherwise.

rule_id	Applies to	Rule	source_ids
alloc_upstream_cut_specific	upstream chilled cut	Use the supplier's cut-specific dataset and its reviewed slaughter/carcass allocation; do not allocate generic live-animal or carcass burdens inside this finishing foreground system.	unece-deer-meat-2013
alloc_no_cross_instance_average	species, cut, bone state, freezing, refrigerant, packaging, and wastewater route	Do not average another configuration with this instance; produce a separately reviewed package.	unstats-cpc-3-2025; unece-deer-meat-2013
alloc_shared_electricity	shared electric meters	Prefer process submeters; otherwise allocate each equipment group's electricity by documented operating time and power or refrigeration-load driver, preserving separate atomic electricity rows. Economic allocation is not permitted.	mass-balance-identity
alloc_refrigerant_by_equipment	R717 make-up and loss	Assign refrigerant by equipment-group mass balance; do not combine blast-freezer and frozen-storage R717 rows.	mass-balance-identity
alloc_waste_no_credit	rejected meat, packaging waste, wastewater, and sludge	Report gross waste leaving each process. Do not apply avoided-burden credit in the foreground inventory; model any downstream recovery as a separate documented system.	mass-balance-identity
