Food Safety Temperature Logs: What to Record and How Often
What to record on a food temperature log, the key safe temperatures to check, how often to check them and what to do when a reading is out of range.

Temperature control is one of the most important parts of food safety — and one of the easiest to let slide on a busy shift. A temperature log is how you prove (to yourself, and to an inspector) that food stayed safe from delivery to service.
This guide covers what a food temperature log should record, the key temperatures to check, how often to check them, and what to do when a reading is out of range.
Why temperature logs matter
Bacteria grow fastest between 41°F and 135°F (5°C to 57°C), often called the "danger zone." Keeping cold food cold and hot food hot slows that growth. A log:
- Catches problems early — a cooler that's drifting warm, or a hot-holding unit that isn't keeping up.
- Creates a record for health inspections and audits.
- Builds habits — when checks are scheduled and recorded, they actually happen.
What to record on a temperature log
Every entry should capture:
- Date and time of the check
- What was checked — the unit (e.g. "Walk-in cooler 1") or the food item
- The temperature reading
- Who took the reading (initials or name)
- Whether it passed — within the safe range or not
- Corrective action, if it failed — what was done and by whom
That last item is the one most paper logs skip. A reading of 46°F with no note about what happened next is a red flag in an inspection.
Key temperatures to check
Cold holding
- Refrigerators and walk-in coolers: food at 41°F (5°C) or below
- Freezers: 0°F (−18°C) or below is the common target
Hot holding
- Hot-held food: 135°F (57°C) or above
Cooking (minimum internal temperatures)
- Poultry: 165°F (74°C)
- Ground meats: 155°F (68°C)
- Whole cuts of beef, pork, lamb and seafood: 145°F (63°C)
Cooling
Cooked food must be cooled quickly:
- From 135°F to 70°F within 2 hours, and
- From 135°F to 41°F within 6 hours total.
Reheating
Food reheated for hot holding should reach 165°F (74°C) within 2 hours.
Receiving
Check cold deliveries on arrival. Refrigerated products should generally arrive at 41°F or below; frozen products should arrive frozen solid with no signs of thawing.
How often should you check temperatures?
The FDA Food Code sets the temperatures but not a single universal schedule; your local code or HACCP plan may set one. Common practice:
| What | How often |
|---|---|
| Walk-in coolers, reach-ins, freezers | At least at opening and closing, often every 4 hours |
| Hot and cold holding on the line | Every 2–4 hours during service |
| Cooking | Every batch of high-risk items |
| Cooling | At the 2-hour and 6-hour marks (and ideally in between) |
| Deliveries | Every delivery of cold or frozen product |
Checking every 2 hours on the line gives you time to fix a problem before food has been out of temperature for long.
What to do when a reading is out of range
Every log needs a clear "if it fails" rule. For example:
- Cooler above 41°F: Check the door seal and thermostat. Move food to another unit. Check how long food has been above 41°F and discard according to your policy. Call for repair.
- Hot-held food below 135°F: Reheat to 165°F if it's within the allowed time, or discard.
- Cooling not on track at 2 hours: Speed up cooling (ice bath, shallow pans) or reheat and restart, per your plan.
Then record the corrective action and make sure someone follows up on the equipment.
Why paper temperature logs fall short
A clipboard by the walk-in is better than nothing, but:
- Entries get skipped, or filled in all at once at the end of the shift.
- Nobody is alerted when a reading fails — it just sits on the sheet.
- Logs get lost, damaged or are hard to find when an inspector asks.
- Multi-location owners can't see what's happening at other sites.
Digital temperature logs with Cayro Ops
Cayro Ops turns temperature checks into scheduled checklist items with number checks and safe ranges. Staff enter the reading; Cayro knows whether it's in range.
- A failed check can open an incident automatically, so an out-of-range cooler gets an owner and a follow-up instead of a note nobody reads.
- Every reading records who, when and where.
- Checks are scheduled in each location's local time, so they show up when they're due.
- Managers can see completion and failures for every location in one place.

Temperature log checklist
- Every cooler, freezer and holding unit has a scheduled check
- Each entry records date, time, reading, initials and pass/fail
- Safe ranges are written on the log
- There's a clear corrective action for every type of failure
- Corrective actions are recorded
- Failed equipment gets a repair follow-up
- Logs are kept for as long as your local code requires
Keep food safe at every location
Temperature logs only work if they happen on time, every time, and failures get acted on. See how Cayro works for restaurants and hospitality, or start a 14-day free trial.
