4 ways to automate fridge temperature checks

#1 - Simple log

Who it's for: Single-site kitchens where the chef or duty manager reads the fridges themselves. No second checker, just a need to record that cold food was kept cold.

What it is: A fridge temperature check is a recorded reading of each fridge's temperature. This version keeps it to the one thing that matters: the number on the display, logged per unit, in one box so each fridge reads as its own check. Cold food must be held at or below 5°C as a target, with 8°C the legal maximum in England, Wales and Northern Ireland. Below 5°C, the bacteria that cause food poisoning grow slowly; above 8°C they multiply fast.

Available on: Basic.

In practice: A single-site deli opens up, walks the line of three fridges, and logs each one: 3°C, 4°C, 2°C. It takes under a minute and leaves a dated record that the cold chain held overnight, which is the first thing an environmental health officer asks to see.

Why it works: Each reading lives in its own box, tied to a fridge, so a number is never logged adrift from what it measures. When you check several fridges, you duplicate the box, and the record stays readable months later.

Steps included:

• 1 grouped check (one box per fridge) holding: fridge temperature (number)
• Duplicate the box for each fridge

When to upgrade:

1. Rota staff are doing the readings and don't all know the safe limit
2. Your EHO wants proof, not just a typed number
3. You run more than one site and want a named sign-off

#2 - With guidance

Who it's for: Kitchens with new starters or a rota of staff who don't all know the safe limit off by heart.

What it is: The simple log with a guidance note added to the box. The note states the 5°C target and the 8°C legal limit, and reminds staff to read the built-in display and check against a probe if a reading looks off. A door display can read a degree or two cooler than the warmest shelf, so the note steers staff to trust the right number.

Available on: Standard.

In practice: A busy cafe with a high-turnover team runs this. A new starter reads the fridge, sees the note saying anything above 8°C needs action, logs 9°C, and knows straight away to move the stock and report it rather than shrugging it off.

What it adds to the previous template:

1. The safe limit is on screen at the moment of the reading, not in a training folder
2. New staff know what counts as a fail without asking
3. Readings are taken from the right place, not just the door display

Why it works: The guidance sits in the same box as the reading, so staff see it as they check, not in a session they have half forgotten. It turns the head chef's standard into a prompt that is always on screen.

Steps included:

• 1 grouped check (one box per fridge): fridge temperature (number)
• 1 guidance note in the box (safe limit and how to read it)

When to upgrade: When a typed number is no longer enough and you want photo proof of the display (Fridge #3), or a named sign-off for an audit trail (Fridge #4).

#3 - With photo evidence

Who it's for: Kitchens under EHO scrutiny, or holding food for vulnerable groups, that want to show proof rather than ask an inspector to trust a number.

What it is: The guided log plus a photo of the fridge display next to the reading. A number typed into a log can be rounded or guessed; a photo of 4°C on the display is proof the fridge was read and was in range at that time.

Available on: Standard.

In practice: A care-home kitchen photographs each fridge display every morning and evening. If the CQC or the EHO questions the cold chain, the kitchen can show the actual display for the actual fridge on the actual day, not a tidy column of identical numbers.

What it adds to the previous template:

1. A photo of the display next to the logged reading
2. Proof that holds up to an inspector, not just a number
3. A visual record that ties each reading to a real fridge

Why it works: Evidence taken in the moment is far stronger than a number recalled later. The photo ties the reading to the fridge and the time, which is what an inspector or an insurer needs.

Steps included:

• 1 grouped check (one box per fridge): fridge temperature (number)
• 1 guidance note in the box (safe limit and how to read it)
• 1 photo in the box (the fridge display)

When to upgrade: When the readings need a named, dated sign-off so an audit can see who confirmed them (Fridge #4).

#4 - With photo and signature

Who it's for: Multi-site groups where a chef or duty manager signs off the day's fridge readings and the records have to stand up across sites.

What it is: The photo log plus a signature. The person doing the readings signs to confirm every fridge was within range. For a group with a food safety manager overseeing several kitchens, that signature makes each site accountable for its own cold chain.

Available on: Standard.

In practice: A 15-site coffee chain logs fridge readings with photos through the day, then the duty manager signs off at close. The food safety lead can open any site's record and see the readings, the photos, and the signature, all timestamped, without leaving the office.

What it adds to the previous template:

1. A signature confirming every fridge was within range
2. Named accountability for each site's readings
3. A complete record (reading, photo, signature) an auditor treats as best practice

Why it works: A signature turns a set of readings into a record someone has put their name to. Nobody can later say the checks were not done. With the photo and the readings, it is the full evidence an EHO or a group auditor wants.

Steps included:

• 1 grouped check (one box per fridge): fridge temperature (number)
• 1 guidance note in the box (safe limit and how to read it)
• 1 photo in the box (the fridge display)
• 1 signature in the box (sign-off)

When to upgrade: When you want Poppi to flag an out-of-range fridge to the manager on its own, or pull every site's readings into one report. Those versions are coming in the next post update.

How to pick the right version

You don't need to know our product to choose. Just answer three questions about how your kitchen runs.

Is it just you reading the fridges, or do other people do it too?

If you read them yourself and know the limit cold, a plain log is enough. The moment rota staff do it, the limit needs to be on the screen. If only you check, #1 is fine. If anyone else does, start at #2.

Do you need proof, or is a record enough?

A record tells you a number was logged. Proof is something you can put in front of an inspector. If a number is enough, stop at #1 or #2. If you are under scrutiny or hold food for vulnerable groups, #3 adds a photo of the display.

Does someone need to sign off the readings?

In one kitchen, the record speaks for itself. Across sites, an auditor wants to know who confirmed each day's readings. If no sign-off is needed, #3 is enough. If you run more than one site, #4 adds a signature.

Frequently asked questions

What temperature should a fridge be?

The target is 5°C or below. The legal maximum for cold food in England, Wales and Northern Ireland is 8°C, but 5°C gives you a safety margin and is what most kitchens aim for. Below 5°C, harmful bacteria grow slowly; above 8°C they multiply fast enough to make food unsafe.

How often should fridge temperatures be checked?

Most kitchens check at least twice a day, at opening and close, and again if a fridge has been opened heavily during service. Record every reading rather than only the ones that pass. An EHO finds a log of identical perfect numbers as unconvincing as no log at all.

Should I read the door display or use a probe?

Read the built-in display for the routine check, since it is quick and always there. Use a probe to verify if the display looks wrong, or periodically to confirm the display is accurate. The warmest part of a fridge is usually the door and the top shelf, so place stock and trust readings accordingly.

What do I do if a fridge is over temperature?

Move the food to a fridge that is in range, or to a cold store, and record what you did. Check whether the fridge was overloaded, the door left open, or the unit is failing. Food held above 8°C for a short time is usually fine; food that has been warm for hours should be discarded. The record of the reading and the action is what protects you.

Where to go next

A fridge check is only as useful as the record it leaves. The gap in most kitchens is not the fridges; it is that nobody logged the reading, so there is nothing to show. The versions above move from a simple log to a signed photo record, so the proof is there when an inspector asks.

Five more versions are coming in the next refresh that bring AI into the check. Poppi can flag an out-of-range fridge to the manager, and pull every site's readings into one report. Those need more review time and will land separately.
