If one permanent ID appears on two containers, records may not distinguish them. This identity issue alone is not evidence of a temperature event.
Why records get mixed
If trip, maintenance and cleaning entries share an ID, histories may merge. Assignment before checking dates and physical features is unreliable.
First review
Record both marks, photos, distinguishing features, inspection time and inspector.
Copy movement and maintenance records for both; do not delete or silently transfer old rows.
Check verified matches such as shipment time, recipient or a second mark inside the lid.
Refer the issue to the authorized role; site process determines ID assignment and prior record links.
How history is linked
For a correction, record old and new IDs, reason, date and approver. Do not assign uncertain entries as fact.
Identity and temperature findings are separate. A collision is a traceability defect; it does not show a temperature rise or affected goods. Review any measured deviation separately by time and device ID.
Matching records
If noticed during washing or maintenance, link the date and work order to each physical description.
Reducing recurrence. Compare new IDs with inventory and record who checked the mark. Confirm retired or reused number rules with the site.
