# Meat of pigs, fresh or chilled

## 1. Scope and Applicability

This PCR applies to raw edible meat from domesticated pigs supplied fresh or chilled at a slaughterhouse or meat-cutting plant gate. It covers carcasses, sides and meat cuts, whether bone-in or boneless, when the product has not been frozen, salted, dried, smoked, cooked, canned, fermented or otherwise further prepared. The representative route is receipt of live pigs, slaughter and dressing, chilling, and cold storage; cutting, deboning, trimming and packaging are included when they are needed to produce the declared market form.

The PCR excludes live pigs as the reference product, edible offal sold as a separate product category, rendered fats, hides or skins sold separately, processed or preserved pork, frozen pork, retail preparation, cooking, distribution after the declared plant gate, and consumer use. Upstream pig production is represented by a separate supplier or background dataset and is not recreated inside the slaughterhouse foreground inventory.

## 3. Reference Flow

| Field | Value |
| --- | --- |
| What | Provision of raw edible pig meat in the declared carcass, side or cut form at a slaughterhouse or cutting-plant gate |
| How much | 1,000 kg net product mass, excluding transport and secondary packaging |
| How well | Food-grade, passed applicable inspection, not frozen or further preserved, and meeting the declared fresh/chilled temperature specification |
| How long or cycle | One production lot at dispatch; no service duration is assigned |
| reference_flow_link | 1,000 kg of the declared fresh or chilled pig-meat product |

| Field | Value |
| --- | --- |
| Reference amount | 1,000 kg |
| Reference product flow | Pig carcass, chilled `452e40cd-9178-4f2e-b248-18c81dd83f43` |
| Reference flow property | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` |
| Reference unit group | Units of mass `93a60a57-a4c8-11da-a746-0800200c9a66` |
| Reference unit | kg |
| Required qualifiers | product form (carcass, side or named cut); bone-in or boneless; fresh or chilled condition; product temperature and measurement point; slaughterhouse or cutting-plant gate; packaging state and included packaging; geography; production route; cold-storage duration; production period |

When constructing a foreground data package, the items listed in `Required qualifiers` must be declared in dataset metadata, process notes, reference flow comment, product description, or an equivalent data package field. Missing required qualifiers make the reference flow definition incomplete for that data package.

## 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 | Record net meat or carcass mass at the declared gate. Exclude transport and secondary packaging; state whether immediate primary packaging is excluded or separately inventoried. |
| `cold_carcass_basis` | pig carcass output | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | kg | When the declared product is a carcass, disclose the cold-carcass definition and excluded body parts; do not silently substitute live weight or hot carcass weight. |
| `temperature_state` | reference product condition | Temperature | degrees Celsius | Record fresh/chilled status, measured product temperature, measurement location and time. A concrete dataset must apply its governing legal or customer specification; for EU-context datasets, other meat is chilled to no more than 7 degrees Celsius unless an applicable authorised exception is documented. |
| `energy_conversion` | purchased electricity and thermal energy | Energy | kWh or MJ | Preserve the measured energy unit and conversion trace. Use 1 kWh = 3.6 MJ when conversion is required; do not combine electricity and thermal energy without retaining their separate carrier identities. |
| `water_volume` | process water and wastewater | Volume | m3 | Prefer metered volume. If mass is converted to volume, disclose density, temperature and conversion formula. |

## 5. System Boundary

The foreground boundary starts when live pigs cross the slaughterhouse gate and ends when the declared fresh or chilled carcass, side or meat cut is ready for dispatch at the declared slaughterhouse or cutting-plant gate. It includes on-site utilities, cleaning and sanitation, chilling, cold storage before dispatch, wastewater handling and treatment attributable to the included operations, and management of slaughter co-products and wastes. Upstream pig rearing, feed production and inbound transport are represented by linked upstream datasets. Downstream distribution, retail, cooking, consumption and end-of-life of packaging are excluded unless the study goal explicitly extends the boundary and reports them separately.

## 7. Allocation and Co-product Handling

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| `alloc_avoid` | all_multifunctional_operations | First avoid allocation by separately metering and subdividing independently operated activities; use system expansion only when a direct, demonstrable substitution can be represented consistently with the study goal. | `eu-pef-2021-2279` |
| `alloc_physical` | inseparable_slaughter_and_cutting_burdens | When subdivision or justified system expansion is not possible, allocate shared burdens using a documented relevant physical relationship that reflects how the process burdens relate to the co-products; do not assume that mass is automatically the relevant relationship. | `eu-pef-2021-2279` |

| `alloc_waste_boundary` | wastes_and_coproducts | Assign no co-product credit to a material classified as waste unless a documented downstream use and the chosen allocation or substitution method justify it; record treatment burdens through the declared waste boundary. | `eu-pef-2021-2279`; `eu-bat-sa-2023` |
| `alloc_disclosure` | dataset_reporting | Report the hierarchy step used, factors for every product and co-product, excluded outputs, price or physical data periods, treatment of edible and inedible outputs, and a sensitivity result when the choice materially affects the reference product. | `eu-pef-2021-2279`; `fao-leap-pig-2018` |

### Calculation Rules

| rule_id | Applies to | Formula or rule | Inputs | Output | source_ids |
| --- | --- | --- | --- | --- | --- |
| `calc_normalize_1000kg` | all inventory rows | normalized amount = period-attributable amount / qualifying reference-product mass x 1,000 kg | attributable flow amount; qualifying product output mass | amount per 1,000 kg reference product | `mass-balance-identity` |
| `calc_energy_total` | slaughter energy QA | convert each carrier to kWh using documented factors, sum purchased heat and electricity, subtract only measured recovered energy, and compare the result with the BAT-AEPL on its stated yearly-average basis | electricity; fuels; purchased heat; recovered energy; carcass output | net kWh per 1,000 kg carcass output | `eu-bat-sa-2023` |

| `calc_mass_balance` | slaughter and cutting batches | compare measured animal or meat inputs with reference product, co-products, wastes, wastewater-borne solids when measured, stock change and documented losses; investigate unexplained imbalance rather than forcing closure | all measured mass inputs and outputs; stock change | mass-balance residual and explanation | `mass-balance-identity` |
| `calc_allocation_factors` | shared burdens | derive factors only after applying the allocation hierarchy; factors across included products must sum to 1 for each shared burden pool | subdivision data; physical relationship data; quantities; prices and price period where used | allocation factor by output and burden pool | `eu-pef-2021-2279` |

### Data Quality Requirements

| requirement_id | Applies to | Requirement | Evidence |
| --- | --- | --- | --- |
| `dq_identity` | reference product and same-category inputs | Product form, bone status, fresh/chilled state, temperature, gate, packaging and Tiangong flow identity must match the declared dataset; a carcass flow must not silently represent a processed or frozen product. | product specification; dispatch record; temperature log; flow UUID check |
| `dq_temporal` | foreground inventory | Use a representative continuous 12-month period where seasonal operation permits; otherwise disclose the campaign dates, production share and reason it is representative. | dated meter, production and dispatch records |
| `dq_measurement` | mass, water and energy | Use calibrated direct measurement where available and retain any shared-service allocation driver and conversion factor. | calibration certificates; meter logs; invoices; allocation worksheet |
| `dq_completeness` | included operations | Cover live-pig input, qualifying product, all material co-products and wastes, water, wastewater, electricity, thermal energy, cleaning materials and refrigerant losses; justify any omitted relevant flow. | signed completeness checklist; process flow diagram; mass and utility reconciliation |
| `dq_mass_balance` | each production stage | Investigate and disclose material residuals; do not use an allocation factor or an invented loss to hide an unexplained imbalance. | batch and period mass-balance worksheet; corrective-action record |
| `dq_allocation` | multifunctional outputs | Retain the evidence for the selected hierarchy step and all factor inputs; price data must state currency, geography, time period and averaging method. | allocation workbook; quantity records; price evidence; sensitivity result |
| `dq_temperature` | fresh/chilled claim | Retain product-temperature measurements and the applicable legal or customer limit at the declared measurement point. | calibrated temperature log; specification; release record |

## 9. Validation Rules

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| `val_reference_identity` | reference flow | Fail if the product UUID, mass property, unit group, reference unit or required product qualifiers are missing or inconsistent with fresh or chilled pig meat. | `unstats-cpc-3-0-2025`; `unece-porcine-meat-2018` |
| `val_boundary` | process coverage | Fail if slaughter/dressing/chilling is omitted for a live-pig starting condition, or if cutting/packaging burdens are omitted when the declared product form requires them. | `codex-cxc-58-2005`; `eu-853-2004` |
| `val_upstream` | upstream supply | Fail if live-pig or purchased same-category input burdens are neither linked to a representative upstream dataset nor explicitly reported as an unresolved coverage gap. | `fao-leap-pig-2018` |
| `val_temperature` | market state | Fail if a chilled product lacks its temperature specification and measurement evidence; flag values outside the applicable specification for review. | `eu-853-2004` |
| `val_mass_balance` | slaughter and cutting inventory | Fail if reference output, co-products and wastes are not separately quantified; flag an unexplained material imbalance for correction. | `mass-balance-identity`; `fao-leap-pig-2018` |
| `val_energy_water` | utility QA | Compare annualized net energy and wastewater discharge with the source-backed pig-slaughter BAT-AEPL ranges only on a comparable exclusive-slaughtering basis; an outlier is a review finding, not automatic replacement by a default. | `eu-bat-sa-2023` |
| `val_allocation` | co-product handling | Fail if shared burdens are allocated without the hierarchy step, factor basis and factors being disclosed, or if factors for a burden pool do not sum to 1. | `eu-pef-2021-2279` |
| `val_reasoned_estimates` | provisional ranges | Treat every `reasoned_estimate` range as a temporary, replaceable QA screen; fail publication readiness if it is used as a mandatory allowed range or as a substitute for collected foreground data. |  |
