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.

Here is the part most operators miss: a log is evidence, not paperwork. An automated, timestamped record does double duty. It keeps the auditor happy, and it is the cheapest proof you will ever own for the arguments that cost real money. A stock-loss claim, an insurance dispute, a customer or supplier pointing the finger over spoiled product. In all of those, the question is the same. Can you prove the cold storage held? A clipboard someone filled in from memory proves nothing. A continuous record with a time against every reading settles it before it becomes a claim. Condition standards keep tightening across food, pharmacy and cold chain, so the record that satisfies compliance today is the same record that wins the argument tomorrow. You build it once and it works both jobs.

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. For the monitoring side end to end, what the sensor measures, the alert path and the log it builds, see cool room temperature monitoring in Australia. 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. Already been woken by a breach? Start with the overnight alarm checks.

What the Food Standards Code asks of a cool room

Standard 3.2.2 Food Safety Practices and General Requirements is the standard behind your log. FSANZ describes it as specifying food handling controls for the receipt, storage, processing, display, packaging, transportation, disposal and recall of food.

FSANZ puts safe temperatures at 5°C or colder, or 60°C or hotter. Read that 5°C as a food temperature, taken with a probe in the warmest part of the food. Your room sensor reads air, and air warms first, so a log sitting on 5°C is a warning rather than a pass. FSANZ also says you need a thermometer if you handle potentially hazardous food. The NSW Food Authority says it must be accurate to plus or minus 1°C.

The 2-hour / 4-hour rule, and what it asks of your log

The 2-hour / 4-hour rule is FSANZ guidance for potentially hazardous food that has left refrigeration. Under 2 hours in the 5°C to 60°C band, you can use the food, sell it, or put it back in the fridge. Between 2 and 4 hours, you can use or sell it, but you cannot put it back. Past 4 hours, throw it out. FSANZ counts that time as a running total across preparation, storage, transport and display. FSANZ keeps it separate from the two-stage cooling process in Standard 3.2.2 clause 7(3). Your log is what tells you whether that clock ever started.

What a state authority asks you to write down

Food regulation runs through the states, so the detail comes from your own authority. The NSW Food Authority sets it out by activity on its Showing food is safe page, written for businesses that process potentially hazardous food and serve it ready to eat. Use it as the template even if your business sits outside Standard 3.2.2A.

• Receipt. The date, the food received and its temperature, each delivery.
• Storage. The temperature of potentially hazardous food in storage, with the date. Daily, or as your standard operating procedure says.
• Display. The temperature on display, or how long the food is out, with the date.
• Transport. The temperature in transit, or how long the food travelled, with the date.

You can meet the requirement with records, or by satisfying an authorised officer another way. Its Standard 3.2.2A page adds more. A record carries the date, the time where that matters, and which food or activity it covers. Once made, NSW says a record must be kept for 3 months. That duty sits on category one businesses under Standard 3.2.2A, the ones that process potentially hazardous food and serve it ready to eat. Check your own state authority before you build the sheet.

A sample cool room temperature log

Below is one day for two rooms. The readings are an example. Copy the columns, not the numbers.

The 14:10 and 14:40 rows are the pair that matters. One records the breach, the other the fix and the stock decision.

Calibrate the gauge, or the log records the wrong number

Your log inherits the accuracy of the gauge behind it. The NSW Food Authority's calibrating thermometers page recommends calibration at least once every 6 months, and says to keep the records. Check the cool room gauge against your calibrated handheld on the same cycle. Put the probe close to the gauge probe. Leave it at least 5 minutes with the door shut.

Paper log or digital log

Both are acceptable. The guidance asks you to show the control, in any format.

A paper sheet costs nothing and survives a blackout. It fails at the gaps. Nobody writes a reading at 2am, and one spilled bucket takes the only copy you own.

A digital log records while the kitchen sleeps and exports in seconds. It fails in a way you do not see, so the system has to tell you when a sensor goes quiet. Plenty of kitchens run both.

Where a HACCP plan fits

HACCP stands for Hazard Analysis and Critical Control Point. The NSW Food Authority says food safety programs are based on the Codex Alimentarius Commission's HACCP system and guidelines. They can also be based on Standard 3.2.1 of the Food Standards Code. A program identifies the hazards, monitors the controls, and sets the corrective action when one slips.

Not every business needs one. FSANZ says only certain high risk food businesses must have a program, and your state licence decides it. Where you run one, your cool room log is the monitoring record for the cold storage control.

What an alarm and an automatic logger change

A logger takes the walk and the memory out of the job. Every reading is time-stamped, logged and kept, and you pull a report for any room and date range in seconds. An alarm covers the part a log cannot. It reaches you while the stock is still saleable, starting with a push, stepping up to SMS, then ringing a phone down your contact list.
