Meat of chickens, fresh or chilled

1. Scope and Applicability

This PCR applies to foreground production of edible meat from chickens (Gallus domesticus) that leaves a slaughterhouse or meat-processing plant fresh or chilled. The representative boundary begins with accepted live chickens at the slaughterhouse gate and ends with inspected, chilled chicken meat ready for dispatch at the plant gate. It covers whole dressed carcasses and declared bone-in or boneless cuts, with or without skin and primary packaging, when they remain fresh or chilled.

The PCR excludes live-chicken farming as a foreground activity, frozen chicken meat, edible poultry offal as the reference product, rendered poultry fat, cooked, seasoned, marinated, cured, smoked, canned, or otherwise prepared meat, retail and food-service operations, consumer cooking, and end-of-life treatment of packaging. A producer may include cutting, deboning, primary packaging, on-site wastewater treatment, or on-site by-product treatment only when those operations occur before the declared plant gate and their inventories are separately disclosed. Product form, chilling method, packaging state, geography, and included optional operations must be stated because they materially affect yield, water, energy, and co-product results.

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
reference_net_mass	Reference product	Mass 93a60a56-a3c8-11da-a746-0800200b9a66	kg	Weigh saleable fresh or chilled chicken meat after chilling and the declared drainage period. Deduct packaging tare, free ice, containers, separately marketed offal, and separately marketed by-products. Normalize the completed inventory to 1 kg net reference product.
product_temperature	Reference product at plant gate	Temperature	°C	Record product temperature using the applicable lot sampling plan. Use 4 °C or below as the default guideline for chilled poultry unless a stricter competent-authority or customer limit applies; retain the actual limit, measurement points, and exceptions.
water_uptake_disclosure	Water-chilled product	Mass	kg	When immersion or spray chilling changes product mass, determine uptake from documented pre-chill and post-drain mass measurements and disclose the method. Do not hide retained water by changing the declared reference amount.
live_mass_basis	Incoming live chickens	Mass	kg live weight	Record both bird count and measured net live weight by lot. Use mass, not bird count alone, for yield and mass-balance calculations.
energy_conversion	Electricity, fuels, steam, heat, and refrigeration	Energy	kWh	Preserve source meter units. Convert MJ to kWh by dividing by 3.6 and disclose lower- or higher-heating-value conventions for fuels. Do not combine purchased electricity and fuel energy until both are converted to the same net-energy basis.
water_volume_conversion	Supplied water and wastewater	Volume	m3	Use metered volume; convert litres to cubic metres by dividing by 1,000. Keep separately discharged non-contact cooling water and stormwater distinct from process wastewater.
packaging_exclusion	Reference product and packaging	Mass	kg	Packaging is excluded from reference-product mass and recorded as a separate input when primary packaging occurs before the declared plant gate.
normalization_denominator	All foreground inventory rows	Mass	per 1,000 kg reference product	Aggregate the declared reporting period first, then divide each flow by net conforming reference-product mass and multiply by 1,000. Do not normalize by total live-bird mass, total carcass mass, or total co-product output unless a source range explicitly uses that separate basis.

starting_condition_role	Foreground-gate input condition; upstream husbandry and feed production are supplied by linked background datasets rather than repeated inside the slaughter foreground
product_classification_scope	Edible chicken meat that remains fresh or chilled under CPC 3.0 21121; frozen meat, edible offal, and prepared or preserved chicken products remain outside this PCR identity
recursive_input_rule	If fresh or chilled chicken meat enters a cutting, deboning, repacking, or rework operation, record it as a separate same-category technosphere input with an upstream dataset and do not recursively reproduce its slaughter inventory in the receiving process
upstream_dataset_requirement	Require traceable upstream datasets for live-chicken production and any inbound transport, electricity, fuel or heat, water supply, chemicals, packaging, refrigerant, and off-site treatment that crosses the selected boundary
disclosure	Declare geography, plant type, product form, chilling method, gate temperature limit, drainage convention, reporting period, included optional operations, treatment ownership, co-product destinations, allocation method, and all deviations from this boundary

boundary_rule_cold_chain	Chilled product	Include refrigeration and handling needed to reduce product temperature rapidly and maintain the declared chilled state through the plant gate. A temporary cold-chain interruption may be represented only when necessary for documented operations and its duration and temperature consequence are recorded.	codex-cxc-58-2005
boundary_rule_upstream	Live chickens and other supplied inputs	Exclude farming, hatchery, feed production, and off-site supply processes from the slaughter foreground, but link their burdens through upstream datasets. Include inbound transport separately when it is not already included in the delivered live-chicken dataset.	ifc-poultry-processing-ehs-2007
boundary_rule_stream_separation	Meat, edible co-products, inedible material, and wastewater	Keep reference meat, edible offal, saleable by-products, condemned material, blood, feathers, other solids, and wastewater as distinct streams. Do not route recoverable organic material implicitly into wastewater.	ifc-poultry-processing-ehs-2007; ec-bat-slaughterhouses-2023
boundary_rule_treatment	On-site and off-site treatment	Include on-site wastewater or by-product treatment burdens when operated within the declared plant boundary.

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
allocation_rule_subdivision	Separately metered operations and outputs	Avoid allocation first by subdividing the process and assigning inputs, wastes, and emissions directly to chilling, cutting, packaging, wastewater treatment, or by-product operations when records support that distinction.	eu-pef-2021-2279
allocation_rule_system_expansion	Multi-functional output systems	If the declared study goal permits system expansion and a representative substituted function is demonstrable, model and disclose the expanded system consistently. Do not apply an avoided-product credit merely because a residue has a possible use.	eu-pef-2021-2279
allocation_rule_physical	Shared slaughter burdens after subdivision is exhausted	When system expansion is not used, prefer a relevant, quantified physical relationship that reflects how shared burdens arise. Document the selected relationship, included output streams, measurement period, and why it represents the process.	eu-pef-2021-2279
allocation_rule_other_relationship	Shared burdens without a defensible physical relationship	If a physical relationship is not defensible, use another documented relationship such as site-specific economic value at the co-product split point. Report prices, currency, period, zero-value streams, and sensitivity to material price changes.	eu-pef-2021-2279
allocation_rule_waste_status	Condemned or inedible outputs	Treat an output as waste unless its legal status, quality, purchaser or user, and actual destination demonstrate a product function. Waste treatment burdens remain with the system that generates the waste unless the selected method and study goal justify another treatment.	ifc-poultry-processing-ehs-2007; codex-cxc-58-2005
allocation_rule_closure	All reference and co-product outputs	The allocation model must include reference meat, edible offal, blood, feet, feathers, fat, skin, other marketed streams, and waste status as applicable; allocation fractions for partitioned burdens must sum to 1 within rounding tolerance.	ec-bat-slaughterhouses-2023; eu-pef-2021-2279

dq_temporal_representativeness	Foreground reporting period	Use at least 12 consecutive months when seasonal throughput or refrigeration loads are material; a shorter complete campaign must state season, product mix, and limitation.	reporting-period declaration; throughput and operating calendar
dq_completeness	Process inventory	Cover every included shift, line, product form, optional operation, co-product, waste route, and material abnormal event. Quantify data coverage and disclose exclusions rather than silently applying zero.	completeness matrix; production reconciliation; incident and downtime log

validation_rule_mass_balance	Material inventory	Require a documented mass-balance residual. Investigate a relative residual greater than 5% of accepted live mass; do not force closure by assigning the residual to the reference product or wastewater.	mass-balance-identity; ifc-poultry-processing-ehs-2007
validation_rule_energy_qa	Total net energy	When a source-compatible cold-carcass basis is available, compare total net energy with the EU BAT screening interval of 170–490 kWh per tonne cold chicken carcass. Treat an outlier as a review trigger, not an automatic replacement value, and explain boundary or technology differences.	ec-bat-slaughterhouses-2023
validation_rule_wastewater_qa	Wastewater discharge	When a source-compatible cold-carcass basis is available, compare wastewater discharge with 1.45–6.30 m3 per tonne cold chicken carcass. Treat an outlier as a review trigger and preserve separately discharged cooling water and stormwater distinctions.	ec-bat-slaughterhouses-2023
validation_rule_evidence	Foreground package	Require source records, collection protocols, calculation inputs, calibration or reconciliation evidence, and explicit disclosure of missing or estimated fields. Reasoned-estimate ranges in this PCR are replaceable authoring aids and must not override collected foreground values.	ec-bat-slaughterhouses-2023
