The way to fill an audit form with concrete evidence is to pick one consignment and follow its records from start to finish: from the dispatch record to the delivery reading, the same product, lot and consignment ID appears on the form. FAO recommends monitoring critical limits with a planned method and a suitable frequency, and having the records reviewed by a person who knows the work and has the authority to act (monitoring guidance).
Cold chain basics move an audit form away from regulatory headings and onto the route the product actually follows.
Follow one consignment step by step
| Stop | Evidence to observe | ID to record |
|---|---|---|
| Acceptance criterion | Written product limits and measurement method | Specification or procedure revision |
| Dispatch preparation | Product/lot, container or vehicle preparation, pre-loading reading | Consignment, container/vehicle and device IDs |
| Loading and waiting | Timeline, dock or door waiting, seal | Start/end times and seal ID |
| Transport | Logger report kept separate from equipment display | Trip ID, data file and reading time |
| Receipt | Receiver reading, acceptance note, damage or delay | Delivery ID, measurement point and receiver |
| Closure | Proof that the finding was corrected and rechecked | Action ID, owner and verification date |
When a passive container is audited, the vehicle-unit row stays empty; that does not mean container preparation went unchecked, because container and plate records take the place of that row. Link the model and container ID, the eutectic plate item, the plates' preparation batch and the pre-loading check to the same consignment ID; the GEBHARDT Isotec TBX and plate-preparation information is the basis for those records.
Write the observed evidence, not yes or no
The answer to "is temperature monitored?" is almost always yes. Instead, open the selected consignment's record: where was it measured, what is the device or file ID, at what time was the value taken? An equipment display and a product reading do not count as the same evidence. The Thermo King Precedent manual lists as separate steps a recorded product-temperature spot check during loading, a load pre-cooled before loading (the unit is designed to hold temperature, not to cool a warm load), and a return-air reading every four hours en route (manual, pp. 125-129).
Equipment gets a record number too: the thermometer's calibration date, the logger's battery state and recording interval, the container's gasket and lid seating, the plates' count and damage.
Finding and closure fields
| Field | Information to enter |
|---|---|
| Finding ID | Number linked to the audit and consignment |
| Observation | What was seen and which record or photo supports it |
| Affected load | Product, lot, container/vehicle and time window |
| Owner | Responsible role and target date |
| Correction | Affected-load segregation and process intervention |
| Closure evidence | Repeat reading, record review or site observation |
| Decision | Result and reason, under the site's procedure |
Sort findings into three tiers: those directly affecting product safety, those leaving a record incomplete, and improvement suggestions; in one list the easiest gets fixed and the important one stays. In an excursion, bringing the process back under control and deciding what happens to the affected product are separate steps. FAO's corrective-action guidance treats those two, the cause investigation and the action record separately (guidance). Add a record number or file path to every row and give the reason for any field left unused.
The tables are example fields to adapt to the site's procedure; the decision to accept or release the product is written on the form under the name of the person who holds that authority.
