Restaurant temperature log sheet: what to record and how often
A restaurant temperature log sheet is a daily record of the temperatures that keep food safe: coolers and freezers, hot holding, cooking, and cooling. Each row needs the date and time, which unit or food, the reading, who took it, and what was done if the reading was out of range. Write each reading when you take it, with the corrective action beside any bad one. That is what an inspector wants to see.
This guide lays out the columns, the limits to print on the sheet, how often to check, filled-in examples, and the mistakes that get a log thrown out. Our free logs are made to match, and the HACCP plan guide shows where the log fits.
What a temperature log sheet is for
A log does two jobs. First, it makes someone look at the number during the shift, so a cooler that has crept to 46°F is caught at 3 pm and not by the inspector. Second, it is your evidence. If you are cited, a log showing regular checks and what you did about problems is the best answer you have. Guides for restaurants say the same thing: record the unit, the reading, the date and time, and any corrective action [3].
Most health departments do not require one exact form. They expect that you check temperatures, and many ask to see the records. The form is yours; the contents are what matter.
The columns every sheet needs
| Column | What goes in it | Why |
|---|---|---|
| Date and time | When you took the reading, not when you filled the sheet | Shows checks happened across the day |
| Unit or food | "Walk-in", "Prep cooler 2", "Chicken thighs, steam table" | Lets the inspector match the log to the equipment |
| Reading (°F) | The number on the thermometer | The evidence itself |
| Limit | Printed on the sheet: 41°F or below, 135°F or above | Staff see at once if they are out |
| In range? (Y/N) | A tick or circle | Quick scan for the manager |
| Corrective action | What you did, in words | Shows the check led to action |
| Initials | Whoever took the reading | Accountability and a person to ask |
| Manager check | Initials and date once a day or week | Verification that someone reads the log |
Limits to print on the sheet
These come from the FDA Food Code [1]. Your state or city may be stricter, so confirm with your health department and print the local number if it differs.
| What | Limit | Check |
|---|---|---|
| Refrigerators, walk-ins, prep coolers, cold wells | 41°F (5°C) or below | Open and close, plus once midday |
| Freezers | 0°F or below is the common target; food should be frozen solid | Open and close |
| Hot holding (steam table, hot box) | 135°F (57°C) or above; 140°F in New York City | Every 2 hours |
| Cooking: poultry, stuffed foods | 165°F | Each batch |
| Cooking: ground meat | 155°F | Each batch |
| Cooking: whole beef, pork, fish | 145°F | Each batch |
| Reheating for hot holding | 165°F within 2 hours | Each batch |
| Cooling cooked food | 135°F to 70°F in 2 hours, then to 41°F in 4 more hours | At start, 2 hours and 6 hours |
| Receiving cold food | 41°F or below on arrival (frozen food hard) | Each delivery |
The two numbers that cause most citations are the first and third rows. In New York City's public inspection data, the violation codes for cold and hot holding (02G and 02B) are the ones this stream's research pulled out, with 2,742 restaurants cited in a 90-day window. A log for exactly those two items is a sensible first sheet.
How often should temperatures be logged?
There is no single legal number. Common practice that inspectors accept:
- Coolers and freezers: at opening and closing, and once in the middle of a long day. Templates sold to restaurants use a grid for open, midday and close [3].
- Hot holding: every two hours while food is on the line. Two hours leaves room to reheat or discard within the four-hour limit the Food Code uses for time without temperature control [1].
- Cooking: each batch of poultry, ground meat or anything else with a cooking limit, at the end of cooking.
- Cooling: three readings per batch: when it leaves the heat, at two hours, at six hours.
- Receiving: every delivery of cold or frozen food, one probe per product type.
If your inspector or city tells you a different frequency, use it. Whatever you choose, write it at the top of the sheet and then do it every day.
A filled-in example
This is what a good sheet looks like at the end of a day, including a bad reading handled properly.
| Date/time | Unit or food | Reading | OK? | Corrective action | Init. |
|---|---|---|---|---|---|
| 11/05 8:05 | Walk-in | 38°F | Y | MR | |
| 11/05 8:07 | Prep cooler 1 | 40°F | Y | MR | |
| 11/05 8:09 | Sandwich cold well | 47°F | N | Moved all product to walk-in at 8:12. Well rechecked at 9:00: 52°F. Called repair, sign on well. Discarded sliced turkey and cheese (unknown time out). | MR |
| 11/05 11:30 | Chicken, steam table | 152°F | Y | JT | |
| 11/05 1:30 | Chicken, steam table | 128°F | N | Reheated to 170°F in oven, back in table 1:50. Table dial raised. | JT |
| 11/05 3:00 | Chili, cooling | 135°F start | Y | In shallow pans, ice bath, 2-hour check at 5:00 | JT |
| 11/05 5:00 | Chili, cooling | 68°F | Y | JT |
Notice what makes it believable: readings differ, times are specific, the bad ones have a plain action, and the first bad reading says what happened to the food.
What to write as a corrective action
Staff freeze on this column. Give them sentence starters printed on the sheet:
- Cold unit above 41°F: "Moved food to [unit]. Rechecked at [time]: [reading]. Food above 41°F for [time]: kept / discarded. Called repair."
- Hot food below 135°F: "Reheated to 165°F in [oven/pan] by [time]. Returned to hold. Rechecked at [time]."
- Undercooked: "Continued cooking, rechecked at [time]: [reading]."
- Slow cooling: "Split into shallow pans and ice bath. Rechecked at [time]. Discarded if still above 70°F at 2 hours and cannot be reheated."
When food has been out of range, most kitchens use the Food Code's four-hour limit as the line: if you cannot show it was out for less than that, throw it out (confirm the rule with your health department). Keep the "discarded" wording in the log. An inspector reading "discarded" trusts the rest.
Calibrating the thermometers
A log is only as good as the thermometer. Check each probe in a glass of ice water: it should read 32°F. Write the date and the thermometer's name or number on a calibration line at the bottom of the sheet, and recalibrate if it drifts more than 2°F or after a drop. Keep a separate thermometer in each cooler, away from the door, so the dial the staff read is the air in the unit; the probe is for food.
Paper, spreadsheet or app?
- Paper on a clipboard by the cooler: cheapest, hard to fake in one sitting, easy to hand an inspector. The usual problem is it gets lost or wet; use a laminated sheet per week.
- Spreadsheet or phone form: fine if staff actually open it. The problem is no timestamp unless the app adds one.
- Sensor and app systems: record every few minutes and alert you. They cost monthly fees and still need a human to write the corrective action.
Any of the three works if the reading, time and action are recorded on the spot.
Mistakes that make a log useless
- Filling in the week on Friday. Perfect handwriting and ink are the giveaway.
- Every reading is the same. 38°F ten days in a row is possible; 38°F for every unit in every check is not.
- Out-of-range readings with no action beside them.
- No limit printed on the sheet, so staff do not know a 44°F is bad.
- One person always initials. It looks like the manager is guessing.
- Logging food temperatures with a thermometer that touches the pan, not the food.

Questions
Is a temperature log required by law?
Rules differ by state and city. Most require you to keep food at safe temperatures and many inspectors ask to see records. Check with your local health department which records they expect and for how long.
How long should I keep temperature logs?
Common asks run from 90 days to a year, and a few jurisdictions say longer. If you have been cited, keep them at least through the re-inspection. Ask your health department for the exact period.
What temperature should a restaurant walk-in be?
41°F or below for the food inside. Many kitchens aim for 36°F to 38°F on the dial so there is room for door openings.
Can I use a free template?
Yes, as long as it has the columns above, the limits printed on it, and room to write what you did. Our free logs are set up for hot and cold holding.
Who should sign the log?
The person who took the reading, and a manager who reviews it daily or weekly.
What if I forgot to take a reading?
Leave the box blank or write "missed" with the time you noticed, and take one now. Never fill in a number you did not measure.
