Cooling cooked food safely: the rules for UK kitchens

Bacteria multiply fastest while food sits between 8°C and 63°C. Cooking takes food out of that range. Cooling drags it back through. That is why cooling is one of the safe methods officers ask about, and why a note that says "left to cool" is not a record.

What you are trying to achieve

There is no single UK criminal offence written as "you missed 90 minutes by four minutes". Food must be kept safe. The Food Standards Agency's Safer Food, Better Business pack tells caterers to cool cooked food as quickly as possible and then refrigerate it. A kitchen can write its own target, such as into the fridge within 90 minutes, if the portions and equipment make that realistic. If your pack states a target, that is the standard you should record against. Leaving a stockpot on the side overnight fails the instruction to cool quickly even if nobody wrote "90 minutes" on the wall.

Large volumes are the usual failure. A 10-litre pot of bolognese can stay hot in the centre for hours while the surface feels merely warm. The fridge is then asked to finish a job it is not designed for, and everything else in the fridge warms up. Cooling is a method, not a corner of the pass you hope will be empty.

How to cool food quickly

Portion it. Split large batches into shallow trays. A depth of a few centimetres cools. A deep pot does not. Metal conducts heat away faster than thick plastic.
Spread and stir. Stir liquids and sauces so the hot centre moves to the surface. Do not stack hot trays on top of each other.
Use cold where the recipe allows. An ice bath under the container, cold water added as part of the liquor, or a blast chiller if you have one. A blast chiller is a tool, not a legal requirement. If you do not have one, the portioning steps are what make the target possible.
Protect the food while it is uncovered. Cool where it will not be contaminated by raw food, dirty cloths, or pests. Cover it once it is cold, then label it with the name and the date.
Get it into the fridge. Do not wait until the end of service "so the fridge is not shocked" if that means hours in the danger zone. If one tray would warm the fridge, you have too much food in one container — split it further.

Rice, pulses, stews, gravies, cooked meats and dairy sauces are the dishes that punish slow cooling. A jacket potato held for later service is the same problem at a smaller scale. Write the dishes you actually cool into the safe method. A generic paragraph copied from a pack, with no mention of the 20-litre rice cooker you use every day, will not survive a conversation with an officer or with a new cook.

What environmental health officers check

Officers look for food that is still hot in a fridge, trays of rice at room temperature at 3pm, and a team that cannot say when cooking finished. They may probe food. They will ask who is allowed to decide that something cooled too slowly to keep. Useful evidence is specific:

The dish, the time cooking finished, and the time it went into the fridge.
Who did it, and the method (shallow trays, ice bath, blast chiller).
A temperature if your safe method says you probe — many businesses probe the centre before refrigeration and again later.
The decision when the target was missed: served immediately under temperature control, cooled faster, or thrown away.

A perfect log with no failures, next to a pot that is still steaming at the back of the fridge, is a worse visit than an honest line that says Tuesday's curry was discarded because service overran. See what inspectors look for in temperature records for the same standard applied to chillers.

What to record

You do not need a novel for every jacket potato. You do need a record for the foods you cool as a regular method, especially rice, meat dishes, sauces and anything you will reheat tomorrow. Keep it short: food, start time, fridge time, person, and a note only when something went outside the method. If you probe, write the reading. If you do not probe, do not invent numbers after the fact because a column looked empty.

The SFBB diary is the natural place for exceptions. A separate cooling sheet is fine if the team will actually use it during service. The failure mode is a sheet kept in the office. Put the prompt where the trays are.

Reheating after cooling

Cool, store cold, then reheat so the food is steaming hot all the way through. SFBB uses steaming hot as the check. GOV.UK’s cooking guidance gives a core of 70°C for 2 minutes, or another listed combination such as 75°C for 30 seconds. Write the check your safe method uses, and do it in the centre of the food, not at the edge of the tray. Reheat only once. Food that has been cooked, cooled, reheated and cooled again has spent too long in the danger zone for a second reheat to be your plan. If you are not sure it was reheated properly, throw it away and record that.

Hot holding after reheating is a different control. In England, Wales and Northern Ireland, food held hot for service is normally kept at 63°C or above, subject to the limited exceptions in the regulations. Do not leave reheated food on a shelf "until the lunch rush" without a hot-hold temperature and a time.

Worked example

A takeaway cooks 8kg of pilau rice at 2pm for the evening. The safe method says rice is spread in trays no deeper than 4cm, stirred, and in the fridge within 90 minutes. At 2:20pm the cook portions it into four gastronorm trays, stirs twice, and probes one tray at 2:55pm: 22°C in the centre. The trays go into the fridge at 3:05pm. The log says "pilau, cooked 14:00, fridged 15:05, Aisha". That is a complete normal entry.

On Friday the rice cooker finishes at 5:10pm, in the middle of service. Nobody portions it until 6:40pm. The centre is still very hot at 7:30pm. The manager decides it will not meet the house target with any margin and bins it, because they cannot show how long it sat above 8°C and they will not serve it tomorrow. The diary says "pilau discarded, cooled too slowly during service, portions were late". The following week they move rice cooking to 3pm and add a second person to the portioning step on Fridays. The 4-weekly review mentions that change. That is a working cooling control, including the failure.

Common mistakes

Putting a boiling pot straight into a small fridge and calling the job finished.
Covering food tightly while it is still steaming, so the heat has nowhere to go.
Cooling raw and ready-to-eat foods on the same tray or in the same sink of ice.
Writing "cooled" with no time, then reheating the next day from memory.
Using the danger zone as a slogan without a dish, a clock, and a person attached to it.

Where this comes from

This guide follows the Food Standards Agency Safer Food, Better Business safe methods on chilling down hot food, cooking, and reheating, and the temperature-control duties in the food hygiene regulations. CookSafe, published by Food Standards Scotland, sets the same expectation of rapid cooling for Scottish businesses that use it. Put your own target, dishes, and equipment into the safe method your team is trained on. The SFBB guide explains how that pack fits the legal duty to have HACCP-based procedures.

Frequently asked questions

How fast must cooked food be cooled?

Cool it as quickly as possible and then refrigerate it. That is the Safer Food, Better Business instruction. If your own safe method adds a time, such as 90 minutes, record the time cooking finished and the time the food went into the fridge against that target.

Can I put hot food straight into the fridge?

Only in portions that will not warm the rest of the fridge. A large pot of hot food cools too slowly and can raise the temperature of food already stored. Use shallow trays and split the batch.

Do I have to write a temperature for every item I cool?

Write what your safe method requires. At a minimum, record the food, the times, and the person for dishes you cool regularly. Add a probe reading if that is the check you have chosen. Record a decision whenever the food did not meet the method.

How hot should reheated food be?

Reheat until it is steaming hot all the way through. GOV.UK’s cooking guidance gives a core of 70°C for 2 minutes, or another listed combination such as 75°C for 30 seconds. Reheat only once, then hot-hold at the temperature your safe method specifies if the food is not served immediately.

What if cooling took too long?

Do not guess a time that fits the target. Decide whether the food can still be used safely under your method or must be thrown away, write that decision, and change the routine if the same dish misses the target again.
