Fridge layout for food hygiene in UK kitchens

Why the shelf plan is a control

Cold slows bacteria. It does not stop drip, and it does not label a tub. Assimilated Regulation (EC) No 852/2004 expects food to be protected from contamination and stored so it does not become unsafe. The Food Standards Agency's E. coli cross-contamination guidance is blunt about storage: raw food is kept away from ready-to-eat food, covered, so nothing can drip onto food that will not be cooked again. Safer Food, Better Business for caterers says the same thing in the chilling and cross-contamination safe methods. The layout is how you make those sentences true in a cabinet that is too small.

The wider separation rules for boards, sinks, cloths and hands are in the raw and ready-to-eat guide. Read that for the kitchen. This page stays inside the fridge: shelves, covers, labels, overcrowding, the warm spots, and the probe you use when the display and the food disagree. The daily numbers, and what officers expect on the sheet, are in the fridge temperature log guide. A perfect log next to a dangerous shelf is still a failure. Officers open the door.

Scottish businesses should follow Food Standards Scotland and CookSafe. The shelf logic does not change with the border. Write the plan for the fridges you actually own, not for a diagram in a pack that shows four cabinets when you have one.

Map the fridges you actually have

List every unit that holds food needing chill control. Give each one the name staff already use: "sandwich undercounter", "raw upright", "dessert display", "walk-in". "Fridge 2" is useless if nobody says fridge 2. For each unit, write what it is for, who may put food in it, and the shelf order. Stick a simple version on the door. The safe method can hold the longer note. A plan that lives only in a folder will be ignored at the end of service, which is when the layout usually breaks.

A single upright in a takeaway is a different problem from a raw walk-in plus a ready-to-eat walk-in. If you can dedicate a fridge to raw meat, poultry and fish, do that, and keep ready-to-eat food out of it entirely. Dedication removes the drip risk that a busy shift will eventually get wrong. If you have only one fridge, the shelf order has to do the work, and the menu may need to shrink until you have the space. Buying a second undercounter is sometimes the real corrective action. A laminated map cannot invent a shelf that is not there.

Include display fridges, bottle coolers if they hold milk or cream for drinks you prepare, and the small salad fridge at the pass. Exclude the staff coffee fridge only if it never holds business food. The moment someone puts a tray of cooked chicken in the staff fridge "because the other one was full", that fridge is in the method. Personal food does not belong in the service fridge. A packed lunch on the salad shelf is an unlabelled, unknown-risk item sitting where food is garnished.

Walk the map on a quiet morning with the person who closes. Ask them where raw chicken goes, where tonight's rice goes, and where they would put a delivery that does not fit. If the answers do not match the map, change the map or change the habit before you print another copy. The map is a set of instructions, not a poster.

Raw below ready-to-eat

In a shared fridge, ready-to-eat food goes on the upper shelves and raw meat, poultry and fish go in lidded containers on the bottom. Ready-to-eat means food you will not cook again, or not cook enough to make a contaminated product safe: salads, cooked rice, cooked meats, desserts, cheese, washed fruit, garnishes, and opened sauces you add at the pass. Raw means food that will be cooked thoroughly, and anything that leaks blood or thaw liquid. Eggs stay in their box, covered, where they cannot drip onto ready-to-eat food. They are not loose on a wire shelf above a cheesecake.

The bottom shelf is a contamination control, not a claim about which shelf is coldest. Commercial cabinets vary. Many are colder near the evaporator, often at the back or the top, and warmer at the door. You put raw food at the bottom so that when a bag leaks, the liquid falls onto a drip tray or the floor of the cabinet, not onto ham. You still have to check that the bottom is actually cold enough for that raw food. If a probe shows the bottom is the warm spot in your particular fridge, you have a problem to solve with a better unit or a dedicated raw fridge, not by moving raw meat above the salad.

Cover everything. A lid, film, or a clean gastronorm lid stops drip and stops ready-to-eat food picking up whatever is on the shelf above. Smell is not the hazard. Juices are. A split bag of chicken inside a clean lidded box, itself sitting in a tray, is a reasonable control. A split bag straight on the wire is not. Check the outside of the box when you put it away. If the outside is wet with raw juices, it does not go onto a shelf that also holds clean containers. Wash the outside or change the box.

Defrosting is the same rule with a clock. Raw food thawing in the fridge sits on the bottom, in a container deep enough to hold the liquid, and nowhere near ready-to-eat food. It does not sit on a tray balanced over the desserts. The thawing guide covers how long and how cold. The layout point is that melt water is raw contamination, and it runs downhill.

Hands reach through the fridge all day. A cook who lifts a raw tray out with one hand and a salad bowl with the other has defeated the shelves. The layout has to make the right grab the easy grab. Raw containers should not need to be moved to reach the milk. If they do, the milk is in the wrong place. Colour-coded boxes help when the lids look the same. The colour-coded equipment guide is the board version of the same idea. A red lid for raw and a white or green lid for ready-to-eat is useful only if everyone uses it, and if the red box is never used for salad "just this once".

Labelling so the shelf can be trusted

Every container you decant, cover, or make in house needs a label the next person can read: what it is, the date it was made or opened, and the use-by you are working to. "Rice" on a piece of tape is not enough if there are three rices. "Rice, cooked 14 May, use by 15 May" is a label. The use-by and best-before guide is the law and the house rule for those dates. The layout fails when labels face the back, fall off in the condensation, or are replaced with a fresh sticker when the old one looked untidy. Do not relabel to reset a date. If the date is wrong, throw the food away or ask a supervisor. A new sticker is not a process.

Put the label on the container, not only on the lid. Lids get swapped. A raw lid on a ready-to-eat tub is a contamination incident, not a filing error. If you use day-dot stickers, train people in what the colours mean this week, and do not rely on colour alone. Colour-blind staff and Saturday agency cooks need the written date. Markers should be the ones you have checked will not wash off in a damp fridge. A label that is illegible by the evening is not a label.

Open cans are decanted. A tin of tomatoes left open in the fridge tastes of metal and, more importantly, is an unlabelled, uncovered risk with a torn metal edge. Empty the tin into a lidded tub, label it, and recycle the tin. Sauces from bottles are fine in the bottle if the cap is clean and the manufacturer's storage instruction, once opened, is followed. Wipe the neck. A crusted sauce bottle on the salad shelf is dirt you have chosen to store with food.

Allergens need labels too. A tub of pesto that contains nuts, sitting unlabelled beside a tub of plain mayonnaise, is how a sandwich is assembled wrongly. Keep allergen-containing foods in closed containers, and do not store them where they can spill onto food you have promised is free of that allergen. Gluten-free cakes do not live under an open bag of flour, and they do not live in a fridge so overcrowded that the flour bag is "just for tonight". The allergen guide is the customer-facing rule. The fridge is where that rule is either true or false.

Rotation is a layout job. Older dates go to the front, newer dates to the back, on the same shelf, not in a pile that hides the short date. The FIFO guide is the full method. If the shelf is too deep for anyone to see the back, it is too deep for the way you work. Use a shallower stack, or make "check the back" part of the closing check for that unit. Food behind food is where out-of-date stock lives.

Overcrowding and air flow

A fridge cools by moving air. When you block the fan, cover the vents, or push food against the evaporator, the display can still look cold while a tray at the front is not. Overcrowding is a temperature failure and a contamination failure at the same time. People rest clean bowls on raw lids because there is no space. They stack above the load line. They leave the door open longer because they cannot find the ham.

Leave space between containers and do not block the fan or the vents. Do not line shelves with cardboard or foil that stops air moving. Do not cover wire shelves with a solid sheet unless the manufacturer says the fridge is designed for it. Food should sit inside the load line marked in many commercial units, not above it, and not jammed against the back plate so hard that one side freezes and the door side stays warm. If you have no load line, leave a visible gap at the back and the top.

The practical test is whether you can put your hand to the back without rearranging the whole shelf, and whether the fan is audible and unobstructed when the door is shut. If Saturday service always ends with the sandwich fridge forced shut on a pile of tubs, you have too much food or too little equipment. The corrective action is to prep less far ahead, add a fridge, or change the menu. Writing "do not overfill" on the door without changing the volume of food is a wish.

Overcrowding also hides cleaning. Spills sit under crates for days. A sticky shelf is not sanitised because the air is cold. Build a gap into the week to empty each fridge, wipe it, and put food back in the mapped order. The cleaning schedule should name the fridges, the frequency, and the rule that food is moved to another cold unit first, not left on the pass while you scrub. A clean fridge that has warmed the rice is not a successful clean.

Where the cold air actually is

Find the warm and cold spots in each fridge before you decide the shelf plan. On a quiet morning, with the fridge already at its set point and not just filled with a warm delivery, probe a container of food or a labelled bottle of water that has sat in each zone: top back, top front, middle, bottom, and the door. Write the readings down once, and again in summer. You are looking for the pattern, not for a single perfect number.

The door and the front edge are often warmer, because they see the kitchen every time someone opens the fridge. Do not store high-risk food in the door if your mapping shows it runs warm. Bottled water and unopened cans are a better use of a warm door than cooked rice or cream. Some teams leave the door empty. That is a good result. The display on the panel reads air, often near a sensor the manufacturer chose, and it can be colder than the food at the front. Your daily log should say whether you record the display, a probe in food, or both. The fridge temperature guide is the record. This page is why a display of 4°C does not prove the rice on the door is at 4°C.

When you do probe food, clean and disinfect the probe first, and do not push a probe that has just been in raw meat into a ready-to-eat product. The probe calibration guide is how you know the instrument is honest. A mapping exercise done with a probe that reads 3°C in ice water will invent warm spots you do not have, or hide ones you do.

Set the thermostat so the warm spot you are prepared to use still holds food at a safe temperature. In England, Wales and Northern Ireland the legal maximum for chilled food that must be kept cold is generally 8°C. The Food Standards Agency recommends running fridges at 5°C or below so a busy service still has a margin. If the only way to keep the front of the shelf at 5°C is a set point that freezes the back, move the high-risk food away from the freezing plate and do not use the warm front for rice, ham or cream. Write that on the map. "Whole fridge is fine" is not a finding if you only looked at the display.

After a delivery, the air temperature will jump. That is not the moment to redraw the map. It is the moment to get the door shut and the new stock spaced so air can recover. Stacking a warm delivery in a solid block at the front is how you turn a short spike into an afternoon of warm food. Spread accepted deliveries so cold air can move around them. Do not accept more than the fridge can take. That decision belongs at the door, in the delivery acceptance guide.

Ready-to-eat foods that need their own thinking

Cooked rice, pasta, beans and other foods you cool and keep are high-risk. They go on a ready-to-eat shelf, covered, labelled, and nowhere under raw meat. They also should not be in the warmest spot you found when you mapped the fridge. Rice is a common cause of food poisoning when it is cooled slowly or stored warm, because spores can survive cooking. The layout will not fix a bad cool-down. The cooling guide has to happen before the tub ever reaches the shelf. Once it is there, the layout keeps it cold and separate.

Salads and cut fruit are ready-to-eat. They sit high, covered, and off raw shelves. Washed salad in an open colander dries out and collects whatever falls. Use a lidded tray. Garnishes at the pass belong in a fridge that is cold, not in a container on the counter with a lid "most of the time". If the pass fridge is the warm one, fix the fridge or hold less garnish.

Dairy and opened sauces follow the manufacturer's instruction once opened, which is usually "keep refrigerated and use within" a stated number of days. That date goes on the label. Do not store milk in the door if the door is warm and the milk is for customer drinks you would be unhappy to serve warm. Cheese for a cheese board is ready-to-eat. Cheese you will cook still should not sit under raw chicken.

Desserts and cream products are ready-to-eat and often vulnerable. They do not live in the raw fridge "because there was a gap". A dedicated dessert shelf or a dessert fridge is easier to defend. If a raw box has ever leaked onto that shelf, the shelf is cleaned and disinfected before desserts go back, and the desserts that were underneath are thrown away. You cannot wipe cream.

Walk-in fridges

A walk-in is a room, so people treat it like a store and stack it like a corridor. Food is off the floor, on racks or pallets that are cleanable, with a gap under the lowest food so you can see spills and so the food is not in the dirtiest air. Raw and ready-to-eat are zoned, not mixed along one rack because the delivery was large. A line of tape on the floor and a sign ("raw this side, ready-to-eat that side") helps if it matches what staff do. Tape that everyone steps over is decoration.

Do not store cardboard outers in the walk-in. Cardboard is dirty, it hides pests, and it blocks air. Decant at the door. Do not store chemicals, empty dirty crates, or the mop bucket in the walk-in to "keep them out of the kitchen". The walk-in is a food room. The light should work. A dark walk-in is where raw boxes get put on the wrong rack.

The door of a walk-in is a temperature control. A door left ajar by a delivery, or a strip curtain tied up, will warm the room even if the compressor is running. Closing checks should include the door. If the door needs a crate to keep it shut, the closer is broken and the crate is not a repair. Write the engineer call on the diary the day you notice, and move high-risk food if the temperature will not hold.

People working inside a walk-in still follow handwashing and protective clothing rules if they handle open food. A goods porter in a filthy coat who rearranges the salad rack is a contamination event. The visitor guide covers contractors who need to repair the evaporator. Cover or remove open food before they start, and clean before you put food back.

Display fridges and undercounters

Display fridges are designed to show food, which means they are opened all day and often run warmer than a storage cabinet. Use them for food you will serve soon, in shallow covered containers, not as a second dry store. Do not pack a display so full that the customer door cannot shut or the vents are buried. High-risk food that has sat in a display above your limit is a throw-away decision, not a "put it back in the walk-in and sell it tomorrow" decision. Write the time you know.

Undercounter fridges at the pass take the worst treatment: door open, warm kitchen, kicks, and a habit of stuffing them at the rush. Map them strictly. Many sites use them only for the mise en place for that service, then clear them. That is a better layout than a week's leftovers jammed beside today's garnish. Seals on undercounters fail quietly. A split seal is a temperature problem and a pest gap. Look at it when you clean the door handle, which should be on the cleaning schedule because every cook touches it.

Saladettes and prep fridges with food in the top pans are a layout and a time control. The pans should be filled for the service, not at the start of the day if they will sit in the danger zone. Lids go on between orders if the unit relies on them. Raw meat is not stored in the same pan rail as ready-to-eat garnish. If the only prep fridge is at the pass, raw preparation happens somewhere else, then the raw food goes back to the raw shelf. The pass is a ready-to-eat place in most small restaurants. Do not fight that with a hopeful tub of chicken at the end of the rail.

Cleaning and rebuilding the layout

When you clean a fridge, move food to another unit that is already cold, or work in small sections so high-risk food is not on the bench warming up. Do not mix raw and ready-to-eat food in the "temporary" crate. A temporary crate is still storage. If you have nowhere cold to put the food, do not deep-clean in the middle of service. Wait until you can.

Use the cloth and chemical the schedule names. A cloth that wiped the raw shelf does not then wipe the dessert shelf. Wash and disinfect in the order that protects ready-to-eat surfaces, or use separate cloths. Rinse chemical off if the product requires it, and let the shelf dry as the instruction says before food goes back. Then rebuild the map, do not put everything back in the order it came out if that order was wrong. Cleaning is the chance to throw away out-of-date food, relabel what is genuine, and restore the gaps for air.

Spills of raw meat juice are a disinfection job, not a wipe with the nearest tea towel. Remove the food that was contaminated. Clean the shelf. Check the shelf below. Write it in the diary if food was thrown away. A spill you "dealt with" and cannot describe is the story officers do not trust.

What environmental health officers check

Officers open the fridge. The layout is visible in a way a policy folder is not. They are asking whether ready-to-eat food is protected, whether the cold chain is real in the warm spots, and whether staff can explain the map without inventing it.

• Raw meat, poultry and fish are below ready-to-eat food, or in a separate fridge, and they are covered. Drip trays are in use, not overflowing.
• Nothing ready-to-eat is stored where raw juices can fall on it, including food under a thawing joint.
• Containers are labelled with the name and the date. Out-of-date food is not waiting to be found by the officer.
• The fridge is not so full that air cannot move. Vents and fans are clear. Food is inside any load line.
• The door is not packed with high-risk food if that door runs warm. Staff can say where the warm spot is, or they can show you they have checked.
• The display temperature and a probe in food are not wildly different without an explanation. The log matches the unit in front of them.
• Cardboard, chemicals, and personal food are not stored with open food.
• Allergen-containing foods are closed and identifiable. Gluten-free or nut-free items are not under filthy bags of flour or open pesto.
• Staff wash their hands between raw and ready-to-eat tasks, and the shelf plan does not force them to handle both at once.

A tidy 4°C on the panel does not cancel raw chicken on the top shelf. A beautiful shelf order at 12°C does not cancel the temperature failure. The inspection checklist is the wider visit. The fridge is often where they decide whether the pack is lived or laminated.

Worked example

A small takeaway has one upright fridge and one undercounter at the pass. The safe method says the upright is shared: top shelf desserts and labelled cooked rice, middle shelf dairy, sauces and salad in lidded tubs, bottom shelf raw chicken and beef in red lidded boxes inside a drip tray. The door is not used for high-risk food. The undercounter holds only that service's garnish, then it is cleared. Both units are mapped on the door. The opener records the display on the fridge log sheet and, once a week, probes a tub of rice at the front of the top shelf.

On a quiet Tuesday they map the upright properly. Top back is 3°C, top front is 5°C, bottom is 4°C, door is 8°C. They stop putting mayonnaise in the door and move it to the middle shelf. The display reads 4°C, which matches the middle, not the door. They write the mapping in the diary so the next supervisor does not "tidy" the mayonnaise back into the door.

The following Saturday the closer stacks eight rice tubs against the back vent because the middle shelf is full of salad. On Monday the display still says 4°C at opening, but the weekly rice probe at the front reads 9°C. The rice that was blocked in has been there since Saturday night. Staff throw that rice away because they cannot show it stayed at a safe temperature. They move the remaining in-date salad so the vent is clear, and they recheck in half an hour. The front of the shelf comes back to 5°C. The diary says what was thrown, who decided, and that Saturday prep is now capped at four rice tubs unless the second fridge is fixed. The owner had been delaying a repair on a broken raw undercounter in the back room. The review names the repair as the action, because the upright is doing two jobs and the layout fails every busy night.

Until the repair, raw meat is prepped earlier and the bottom shelf is kept clearer, and they refuse the extra chicken delivery that will not fit in the drip tray. That is a layout control: less food, in the right place, with a probe that was allowed to disagree with the display.

Common mistakes

• Raw meat on the top shelf because "the bottom was full".
• Uncovered food, or lids that do not match the tubs.
• Using the door for rice, ham, cream or custard.
• Blocking the fan and trusting a display that reads the wrong part of the cabinet.
• Cardboard outers and vegetable sacks stored in the walk-in.
• Unlabelled tubs, or new stickers put on old food.
• Personal packed lunches beside the garnish.
• Thawing chicken on a tray above the desserts.
• Cleaning the fridge by leaving high-risk food on a warm pass.
• A shelf plan that needs four fridges when the site has one, and no decision to buy, dedicate, or shrink the menu.
• Allergen foods in open pots that can spill onto food you tell customers is free of that allergen.
• Stacking so deep that short-dated food at the back is never seen.

Where this comes from

Storage and protection from contamination come from assimilated Regulation (EC) No 852/2004, Annex II. The Food Standards Agency's E. coli cross-contamination guidance sets out the separation of raw and ready-to-eat food, including in storage. Cold holding, the 8°C legal maximum in England, Wales and Northern Ireland, and the practical target of 5°C or below are in the Agency's chilling guidance and in Safer Food, Better Business for caterers. Scottish businesses should follow Food Standards Scotland and CookSafe. Map the fridges you have, put the order on the door, and check at the 4-weekly review that Saturday's shelves still match the map.
