Separate the hand that wrote the record from the hand that reviews it, put the day's entries against the lot, and hold the pack for a reviewer 9 CFR 417.5(c) permits to sign.
A lot closes, and 9 CFR 417.5(c) wants its records read before that product ships.
02
A pack reaches review, and the same rule bars whoever produced those records from signing.
Reason
03
A review happens, and it counts only once conducted, dated and signed by that separate hand.
04
A year turns, and 9 CFR 417.4(a)(3) forces reassessment, with 417.2(d) bringing the signature.
05
An entry is written, and 9 CFR 417.5(b) wants date, time and the initials of whoever made it.
Decide
06
A sanitation shift ends, and 9 CFR 416.16(a) wants those daily records initialled and dated.
07
A US-origin claim rides on the pack, and 9 CFR 412.3 wants a signed, dated document behind it.
Out
08
A misbranded lot enters commerce, and 9 CFR 418.2 leaves a day to tell the District Office.
09
Execute write actions only inside the approval boundaries agreed during implementation.
→Product statement
The agent assembles records and tracks the clocks. A named establishment individual, one who produced none of them, conducts, dates and signs under 9 CFR 417.5(c).
Example workflow
One lot, records to signature
AgentHuman
1Lot records receivedMonitoring entries, deviation logs, corrective actions or sanitation records
2Lot context assembledThe lot, its production day, the critical limits it ran against and who made each entry
3Review pack draftedThe entries, the hands that wrote them, the gaps and completeness
4Controls appliedAuthorship checks, critical-limit completeness checks, date checks and completeness confidence
No human action required
Stages 1 to 4 run unaided, and nothing is signed at any of them — the agent is assembling, and the review lane opens at the completeness gate.

Independent review
The pack is held with its lot, its entries and the authorship behind each one.

One lot, annotated
Part 417 has run since 61 FR 38868 of 25 July 1996; this record is what one lot carried on its way to release.

03Records
Where the records are used
Our QA and HACCP assistant is the FDA-side monitoring desk under 21 CFR Part 117 for a preventive controls qualified individual, whereas this page is the pre-shipment release and the annual reassessment under FMIA and PPIA for a different signer — and what that page flags as good practice, an entry whose author is also its proposed reviewer, 9 CFR 417.5(c) forbids outright.
01Approved path
The writer cannot be the reader
9 CFR 417.5(c) wants the review "conducted, dated, and signed by an individual who did not produce the record(s)".
02Human review
What was checked, and not found
Salmonella was withdrawn as a proposed adulterant in raw poultry at 90 FR 17344 on 25 April 2025, the proposal at 89 FR 64678 of 7 August 2024 having drawn its comments, and no successor stands as of 24 August 2026; the line-speed rates at 91 FR 7926 of 19 February 2026 are proposed only, comments having closed on 20 April 2026 with no final rule.
04Build an evidence trail
The lot, the record supporting it and the reviewer who did not write it stay together.
Integrations
Typical integrations
Five system groups connect to the same agent. Which of them are in scope is decided in discovery.
HACCP monitoring and CCP recordsPlant systems · e-forms CCP entries and deviations
Sanitation and pre-operationalSSOP records · shift logs Daily sanitation entries
Shipment and lot releaseERP · warehouse systems Lot, pallet and load records

How Nestack evaluates it
Evaluate the whole assembly — not only the review pack that comes out.
Coverage runs the whole depth of the workflow, and every layer is cut by slice.

A lot-level reviewer-independence figure can read clean while the lots that carried a corrective action take most of the rework. Nestack reports the correction rate by lot category, not only in total.

Evidence-linked improvement
What a self-reviewed record costs
A loop ends when the self-reviewed record has become a case the next release must pass. That suite is what the next lot held is measured against.
Improvement cycle · five stagesSwitchback — the path turns at Improve and returns at Learn
01Detect
Correction rate rises on lots carrying a corrective action.
02Diagnose
The reviewer's initials that turned out to belong to the man who wrote the line are read back until one cause is left standing.
03Improve
Number the change; the lots that drove it are filed underneath it.
04Verify
Each touched lot case is run once more, and one red holds it back.
05Learn
It stays on as a standing test, and the reviewer rules move alongside it.
Learn → DetectThe return edge. Detection next time starts from a suite one case longer.

Next step · Food & Beverage AI agent
Build a pre-shipment review agent around the lot your reviewer has to sign for.
Show us one lot and the records it consumed. Whoever produced those records may not review them, and 9 CFR 417.5(c) settles that rather than your rota. Preventive-controls monitoring under 21 CFR Part 117 is a different agent.
