Identity Preservation

Identity Preservation · Traceability from field to intake

Identity preservation ensures grain remains correctly classified and traceable from field through intake. Without it, quality data is unverifiable and GF certification is indefensible.

Non-Negotiable Controls

Control	What It Protects
Lot-level labeling at every handoff	Ensures grain identity is documented at each transfer point — not reconstructed after the fact
Segregated storage and transport pathways	Prevents cross-contact with non-GF grains during storage, transit, and handling
Documented cleaning and changeover procedures	Creates an auditable record that equipment was properly cleaned between different grain types
Chain-of-custody records tied to lot IDs	Links every quality measurement back to a specific lot — essential for root-cause analysis and certification

Failure Consequence

Weak identity control doesn't just create compliance risk — it invalidates your quality data. If you can't confirm what lot a sample came from, the measurement is worthless for troubleshooting.
