# Meat of sheep, fresh or chilled

## 1. Scope and Applicability

This PCR applies to net, conforming sheep meat placed on the market fresh or chilled under CPC 3.0 code 21115. The foreground begins with live sheep accepted at the slaughterhouse and covers lairage, slaughter and dressing, carcass chilling, cutting, packaging, chilled storage, sanitation, and on-site wastewater handling through the factory gate.

Frozen sheep meat, edible or inedible offal as reference products, rendered products, prepared meat, and meat of species other than sheep are excluded. Sheep farming, feed production, live-animal transport, distribution, retail, cooking, use, and end-of-life are outside the foreground boundary and require separate traceable datasets when included in a wider study.

## 5. System Boundary

The foreground starts when live sheep are accepted at the slaughterhouse gate and ends when conforming fresh or chilled sheep meat leaves chilled storage at the factory gate. Animal husbandry and inbound livestock transport remain upstream. The foreground includes directly operated and subcontracted slaughter, chilling, cutting, packaging, sanitation, and wastewater operations when they contribute to the declared product.
