Fridge Temperature Log: How to Keep One (with Example)

A fridge temperature log is a daily record of the temperature in every refrigerator, freezer and walk-in cooler, with the date, time, the name of the person who checked, and a note of what was done if the temperature went outside the safe range. It helps you spot failing equipment in time, save the food, and show an inspector that storage conditions were kept. Here's what columns the log needs, how often to take readings and what to do when something goes wrong.

Why you need a temperature log

Fridges don't fail in plain sight: the temperature creeps up gradually, at night or over the weekend, and food spoils at the back of the unit. A log does three jobs:

• food safety — a temperature problem is caught within the shift, not after the food has gone off;
• equipment health — the records show which unit keeps drifting and needs servicing;
• evidence for inspections — the records prove that storage conditions were maintained.

Food hygiene rules in most countries require cold-holding temperatures to be controlled, and businesses working under HACCP usually treat the fridge log as one of their key monitoring records (see HACCP explained in plain terms). The exact requirements — what must be recorded and how often — depend on your local regulations, so check them with your food safety authority.

What to record

The minimum set of columns for a fridge temperature log:

Each unit should have a number that matches the log, and its own safe range. One limit "for everything" doesn't work: a freezer and a dairy fridge have different limits.

Filled-in example

The ranges in the example are illustrative. Take your actual limits from local regulations, the manufacturer's storage conditions and your HACCP plan.

What temperature is safe

There's no single universal figure: the safe temperature depends on the type of food, the manufacturer's storage conditions and your country's rules. Common reference points:

• chilled food (meat, fish, dairy, ready-to-eat dishes) — usually between 0 and about +5 °C; many jurisdictions set the upper limit somewhere between +4 and +8 °C;
• frozen food — −18 °C or below;
• fruit and vegetables — a wider range that depends on the product.

Enter the limit stated in your regulations or on the packaging, not "cold enough". It also helps to set a target range slightly narrower than the limit: when the temperature approaches the edge, check the unit before it becomes a deviation.

How often to take readings

Regulations typically require daily checks, and the business sets the exact frequency in its food safety plan. A common practice:

• twice per shift — at the start and at the end;
• additionally — after a large delivery, after defrosting or a repair, during hot weather;
• for freezers in an automatic defrost cycle — re-check after 30–60 minutes if the temperature briefly rose.

Measure the same way every time:

1. Use a thermometer inside the unit on the middle shelf, not just the display on the door: the built-in sensor may sit next to the evaporator and read better than reality.
2. Don't take a reading right after the door has been open for a long time.
3. Check your thermometers against a reference or have them calibrated periodically.
4. Write down the actual value even if it's out of range. A "corrected" number is more dangerous than an honest one.

What to do when the temperature is out of range

A "+9 °C" entry with no action is the most common finding in an inspection: the problem was seen, but nothing was done. The steps:

1. Re-check the reading with a probe in a container of food or water.
2. Protect the food — move it to a working unit.
3. Assess the food: roughly how long it was warm and what kind of product it is. The decision — use, reprocess or discard — is made by the person responsible, following your HACCP plan.
4. Fix the cause — a door left ajar, overloading, ice build-up, a faulty compressor; call an engineer if needed.
5. Record everything you did, plus a follow-up reading after the fix.
6. Prevent a repeat: if the same unit keeps drifting, it needs a bigger fix — repair, a new door seal, a different loading plan.

To check the fridge itself, use the refrigerator and freezer checklist: it covers loading, door seals, ice and separating raw from ready-to-eat food. Cooking and cooling temperatures are monitored separately — see the cooking, cooling and hot-holding checklist — and the temperature of incoming deliveries in the food receiving checklist.

Paper vs digital temperature log

The main problem with paper logs is that they get filled in "from memory" before an inspection, and every entry looks perfect. A digital log doesn't make the data honest by itself, but it makes backdating harder and keeps deviations from getting lost. Most food safety frameworks accept electronic records; if the inspector wants paper, print the log for the period.

Common mistakes

• Every entry is identical ("+4, +4, +4") — an inspector will suspect it was filled in in advance.
• An out-of-range temperature is recorded, but there's no action.
• Bar and service-counter fridges are missing from the log — they were "forgotten".
• Unit numbers in the log don't match the labels on the equipment.
• The thermometer sits by the door or the evaporator, not on the middle shelf.

Temperature logs in jeCheck

In the HACCP module, temperature logs are filled in from a phone or tablet right in the kitchen.

• Limits for fridges and freezers come from your country profile (Kazakhstan, Russia, Uzbekistan, or an international profile based on Codex); a target range gives a warning before a deviation.
• The server records the time of each entry; missed readings are visible right away, and the manager gets a summary.
• A value outside the limit opens a deviation that can't be closed without a correction and a decision on the food — and, for critical ones, a cause and a preventive measure.
• The log for any period prints in a ready form for the inspector, and every unit has a chart with its safe range.
