Cool room temperature log requirements, in plain English.

What a cool room temperature log must record

A log is more than a number scribbled on a sheet. One you can actually stand behind answers five basic questions for every check:

• Which unit was checked, named clearly, so Coolroom 1 is never confused with the display fridge.
• When it was checked, with date and time, not "morning".
• What temperature was recorded, the actual reading.
• Who checked it, so there is a name against the entry.
• What corrective action was taken if the reading was outside the accepted range.

That last one is the part most clipboards miss. A row of in-range numbers tells an auditor very little. A record that shows a breach was spotted and acted on tells them your system actually works. That is the difference between a log and a habit.

What temperature you are logging against

Under the Australia New Zealand Food Standards Code, cold potentially hazardous food should be kept at 5°C or below. Most operators run a coolroom at 2°C to 4°C to hold a margin for door openings and peak loading, and freezers at around minus 18°C or colder. The food safety danger zone runs from 5°C to 60°C. Your log exists to prove the room stayed on the safe side of that line.

How often to check

Manual checks are commonly done at least twice a day, at open and close, and more often in hot weather or during a big delivery. The honest weakness of manual checking is the gap between checks. A coolroom that fails at 11pm on a Friday and is found at 8am on a Saturday has nine unlogged hours, which is exactly when most spoilage happens and exactly what a clipboard cannot see. Continuous logging closes that window by recording every reading around the clock.

How long to keep the records

Temperature records must be available to an authorised officer on request, and are generally kept for at least three months. Your council Environmental Health Officer is the person who turns up, often without warning, and asks to see them. Requirements vary by state, territory and product, so treat this as orientation, not legal advice, and confirm the detail with your local council. Keeping records longer costs you nothing when they are electronic, so there is no reason to bin them at three months and one day.

What an auditor actually looks at

Officers are not trying to catch you out on one warm reading. What they want to see is a system that is running and being watched. In practice that means three things. First, the log is complete, with no obvious blank days where someone forgot the clipboard for a fortnight. Second, when a reading went out of range, there is a matching corrective action beside it, so a breach became a decision rather than a mystery. Third, the record is contemporaneous, meaning it was written at the time and not filled in from memory the morning of the visit. A perfect run of numbers that all look suspiciously identical raises more questions than a real log with the odd spike and a note explaining it. Honest beats tidy every time.

Set sensible thresholds, not just a number

The reading on its own is only half the story. A coolroom will always drift up briefly during a restock or a delivery, then pull back down, and that is normal. What matters is how long it stayed high, not that it touched a number once. A good log, and a good alarm, works on duration as well as temperature, so a two-minute door-open blip is not treated the same as a compressor that quietly died at midnight. Pick a target, pick how long you will tolerate a breach before it counts, and write both down. That is the difference between a system that cries wolf and one you actually trust.

Why automatic logs beat the clipboard

The manual log is the weak link, and everyone in a busy kitchen knows it. On a heavy shift it gets skipped, back-filled at the end of the night, or lost. "We usually check it twice a day" is not evidence. Continuous automatic logging produces a timestamped record for every room, kept and ready to show, with nothing riding on someone remembering to walk over with a thermometer. When an officer asks, you export the report instead of hunting through a folder.

One honest caveat. A monitoring system produces HACCP-ready records that help you demonstrate control. It does not certify you, and no vendor can promise you a pass. Certification and audits are carried out by accredited bodies and your council EHO. Good records simply make your case easy to show.

From logging to alarm

A log tells you what happened. An alarm tells you in time to do something about it. The same sensors that build your cool room temperature log can also escalate a breach to your phone, push then SMS then a call, so you are not just keeping a tidy record of the night your stock was lost. For how the alarm side works, see our coolroom alarm guide. If you also need to log fridges, freezers, a server room or a vaccine fridge, the wider Temperature Monitoring service covers those on one dashboard.
