Raw-Material Lesions and Trimming Defects

Lesions and trimming defects originate before formulation. They include local pathology, bruising, contamination, damaged tissue and tissues that should have been removed under inspection or purchase specifications.

Some localized defects may be removed under competent inspection and control, while generalized disease or systemic involvement affects the whole carcass or lot. A processor should not improvise disposition from appearance alone.

Feces, ingesta, milk, abscess contents and dirty trimming tools can spread contamination beyond the visible defect. Removing the obvious tissue does not reverse cross-contamination already created.

Bruises, blood, glands, connective tissue and damaged fat can create colour, flavour, oxidation, texture and shelf-life faults even when they are not the primary safety concern.

Use purchase specifications, inspection status, supplier lot identity and representative examination. Segregate suspect material and document the defect before trimming or disposal.

Approve suppliers, define rejection and trimming criteria, maintain hygienic tools and surfaces and preserve traceability. Curing, smoking or cooking should not be used to legitimise unfit raw material.
