# Meat of Cattle, Fresh or Chilled

## 1. Scope and Applicability

This PCR applies to foreground data packages for cattle meat leaving the producing facility fresh or chilled. The normal boundary starts with live cattle accepted at the slaughter facility gate and ends with saleable meat at the producing facility gate after slaughter and dressing and, when applicable, chilling, cutting or deboning, packaging, and cold holding.

Covered products are cattle carcass meat and saleable bone-in or boneless cuts in a declared fresh or chilled state. Excluded reference products are live cattle, buffalo meat, edible offal, hides, rendered products, frozen cattle meat, prepared or preserved cattle meat, and retail or food-service products. Cattle raising and inbound transport are upstream; post-gate distribution is downstream.

## 2. Product Category Identity

## 3. Reference Flow

| Field | Value |
| --- | --- |
| What | Saleable cattle meat at the producing facility gate in the declared fresh or chilled state |
| How much | 1 kg net product mass, excluding packaging |
| How well | Declared product form, cattle class where known, intended-use grade, bone status, packaging state, thermal state, dispatch temperature, and included route |

| Field | Value |
| --- | --- |
| Reference amount | 1 kg |
| Reference product flow | Beef `06f53118-716c-472d-b6f2-c5924840395c` |
