If a run log and wash log comparison has no entry for a container, it shows only that the record is missing. The container may have been washed but not logged, or not washed.
Match independent traces
- To check whether the line ran, consult shift schedules and equipment records.
- Water or chemical use is an aggregate process record; alone it does not show a specific container was washed.
- A drying-area position matched to container ID and time is a supporting trace.
- A later receipt-condition record describes what was observed then, not the earlier wash.
Limit the compliance conclusion
A missing record does not prove washing was skipped; supporting traces may not settle it either. State what question each trace can answer.
A confirmed missed wash
If a missed wash is confirmed, handle it separately from a record error under the site's hygiene plan. Verify relevant product and run details from records; release or customer-notification decisions belong to the authorized process.
Report three outcomes separately
Separate three monthly outcomes: record found, record missing and wash confirmed as skipped. Keep an unverified entry uncertain; do not add a retrospective guess.
Close with traceability
If a correction is made, retain the original entry, correction date, supporting basis and approving role. Follow site procedures for clean/dirty area separation and record steps.
