Temperature log basics

Who is responsible for temperature logs

This is a continuation of Temperature log basics, a 4-part tutorial. You are on part 3 of 4.

The person in charge of each shift is responsible. Under the FDA Food Code, they must oversee staff's routine temperature checks every day, and the permit holder must make sure a person in charge is there whenever the place is open.

In practice, the job splits three ways. The person on the round takes and writes each reading. The person in charge reads the log that shift and acts on anything high. One named owner keeps the plan, the thermometers and the files. Logs go blank, or get faked, when one of those three has no name.

The Food Code puts it on the person in charge

The FDA Food Code is the model code that state and local food rules in the US are built on. It names one role for this: the person in charge, or PIC.

So the PIC does not have to take every reading. They have to make sure the readings happen, and that they are real.

The job splits three ways, and each part needs a name

The three roles behind every temperature log.
RoleUsuallyDoesHow often
TakerThe team member on the roundTakes each reading, writes it at the time with initials, and flags anything out of rangeEvery check
CheckerThe person in charge of the shiftReads the log, chases blanks, makes sure every high reading has an action, and initials the logEvery shift, at least daily
OwnerThe kitchen manager or food safety leadDecides which boxes and how often, keeps thermometers checked, trains takers, files the logs, and looks for trendsWeekly, and whenever something changes

A state school log shows the same split on paper: initials for each entry, and a box for the manager's initials and the date, with the manager reviewing it "each working day".

In a food plant under FDA preventive controls, the checker's job has a deadline in law. Monitoring and corrective action records are reviewed "within 7 working days after the records are created", by or under a preventive controls qualified individual (21 CFR 117.165).

Logs go blank where nobody's name is on the job

A missed log is often not a person refusing the job. It is a job nobody was sure was theirs. In our research, long-term care dietitians described exactly this: not knowing who owned the daily fridge and freezer logs, and audits spent chasing unfilled ones.

The gaps tend to open in the same places:

The fix is plain. Put a name against every round on the rota, the same way you would for opening and closing, and hand the log over in person at shift change. A job with a name gets done, or gets noticed when it is not.

A job with too many rounds for the people on shift is the other way logs fail. They get filled in later from memory, which is the subject of pencil whipping temperature logs.

Responsibility does not stop when the doors close

The box keeps running after everyone has gone home. If a compressor stops at midnight, the person who finds out is the opener at 6 AM. On paper, nobody is responsible for the hours in between.

Name who gets the call at night, and a second person if the first does not answer. TemperatureWise does this per sensor: email to as many people as you want, and texts, WhatsApp messages and phone calls to up to 3 people, escalating until someone answers. How to set that up is in alerting more than one person.

TemperatureWise takes the readings, and the people keep the judgment

TemperatureWise records each box at least every 15 minutes and keeps the record indefinitely. The taker's rounds can be fewer, and the checker reads a full day of readings, not a few numbers.

The owner still decides what to monitor. The person in charge still decides what happens to the food when a box goes wrong, and still signs for it.

Common questions

Who is responsible for checking fridge temperatures in a restaurant?

The person in charge of the shift. Under the FDA Food Code, they must oversee staff's routine temperature checks every day, even when a team member takes the readings.

The permit holder must make sure a person in charge is present during all hours of operation.

Who should sign a temperature log?

Two people: the one who took each reading initials it, and the person in charge initials the log once they have read it that day.

Federal rules for food plants ask for the initials of the person who did each check, and a state school log, for example, has a box for the manager's initials and the date.

How often should a manager review temperature logs?

Every day, before the shift ends. The Food Code calls for daily oversight by the person in charge, and school food logs ask the manager to review them each working day.

Food plants under FDA preventive controls must review monitoring and corrective action records within 7 working days.

What happens if nobody fills in the temperature log?

You lose the proof that food stayed at 41°F (5°C) or colder, and the inspector sees the gap. If you cannot tell how long food was warm, school kitchen guidance is to throw it out.

Gaps usually mean the job had no name. Put a name on every round, and read the log daily, so a blank is found the same day.

Can the person in charge hand temperature checks to someone else?

Yes. Team members can take the readings, and the person in charge stays responsible for making sure they are done and are right.

Train each person on where the thermometer goes and what to write when a reading is high. Training staff in their duties is also part of the PIC's job under the Food Code.

Want the night shift covered

TemperatureWise watches every box after close and calls the people you name, in order, until one of them answers.
