# Meat of buffalo, fresh or chilled

## 1. Scope and Applicability

This PCR applies to slaughterhouse-gate production of buffalo meat released fresh or chilled within CPC 3.0 subclass 21112. It covers receiving live buffalo, slaughter and dressing, evisceration and standard cutting, deboning where used, chilling and refrigerated holding, cleaning and disinfection attributable to those operations, conditional on-site wastewater treatment, final inspection, and conditional sale packaging.

The foreground begins with live buffalo accepted at the slaughterhouse gate. Buffalo farming and inbound transport are represented by upstream datasets rather than foreground operations. Retail, food preparation, consumption, and end of life are outside the foreground boundary.

Frozen buffalo meat, edible offal, non-edible offal, hides, blood, fat, bones, and waste are not part of the reference product. Each is recorded separately when produced. Every inventory card represents one atomic exchange, and conditional technologies or materials are recorded only when supported by facility records.

##### Elementary flows

## 7. Allocation and Co-product Handling

| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| `allocation_subdivision` | separately_metered_processes | First avoid allocation by subdividing slaughter, cutting, chilling, wastewater treatment, and packaging when their inputs and outputs are separately measured. | `eu-recommendation-2021-2279` |
| `allocation_mass_balance` | all_material_outputs | Reconcile live mass and each process transfer against reference meat, blood, hide, liver, heart, fat, bones, wastes, stock change, moisture change, and measured losses before allocating burdens. | `ec-jrc-sa-bref-jrc135916`, `eu-recommendation-2021-2279` |
| `allocation_co_products` | blood_hide_organs_fat_bones | When subdivision cannot isolate burdens, apply and disclose a product-specific physical causal relation; if no defensible physical relation exists, use documented economic allocation with matching-period prices and sensitivity disclosure. | `eu-recommendation-2021-2279` |
| `allocation_waste_status` | waste_and_recovered_outputs | Classify each output as product, waste, or emission from its actual legal and operational destination; revenue or avoided treatment alone does not justify silently changing flow type. | `ec-jrc-sa-bref-jrc135916`, `eu-recommendation-2021-2279` |
| `allocation_shared_utilities` | shared_meters | Allocate shared utilities using a documented causal driver such as equipment submetering, operating time and rated load, treated volume, or refrigerated mass-time; disclose residual unallocated use. | `ec-jrc-sa-bref-jrc135916`, `eu-recommendation-2021-2279` |
