ロット追跡性：購買業者が期待すべきこと
Traceability is not just a checkbox—it is your insurance policy when problems occur. In frozen vegetables, effective traceability means you can quickly identify what was produced, when, from which raw material lot, on which line, and where it was shipped.
A practical traceability system typically includes:
- Clear batch coding on cartons and inner packs
- Raw material receiving logs (supplier, date, lot, grading)
- Production records (line, shift, processing parameters, yields)
- Critical control monitoring (metal detection checks, temperature logs)
- QA release documentation (COA, microbiological test references)
- Dispatch records (container loading time, cold chain status, destination)
What buyers should do:
1) Ask for a sample traceability pack for one batch.
2) Verify whether documents connect logically: inbound raw lot → production lot → finished batch → shipment.
3) During audits, request a mock recall exercise: “Show us how you would trace Batch X within 2 hours.”
A supplier with disciplined traceability is usually disciplined in many other areas—quality consistency, complaint handling, and continuous improvement.
