1. Scope and Applicability

This PCR governs foreground data packages for cattle edible offal classified exactly as CPC 21151. It covers facility operations from cattle receiving through slaughter and evisceration, organ-specific separation, trimming, washing, inspection, conditional chilling or freezing, composition assembly, packaging, storage, release, cleaning, and conditional on-site wastewater treatment.

The reference product is 1 kg net conforming cattle edible offal at the facility gate. The data package must declare every organ in the composition and exactly one market state: fresh, chilled, or frozen. Buffalo edible offal and edible offal of every non-cattle species are excluded. Cattle rearing and inbound transport are upstream; distribution after the facility gate, retail, use, and end-of-life are downstream.
