Separating raw and ready-to-eat food in UK kitchens

What you are trying to achieve

The legal duty is plain. Food must be protected from contamination that would make it unsafe. Assimilated Regulation (EC) No 852/2004 requires food businesses to keep raw and ready-to-eat work adequately separated, and to keep surfaces and equipment clean and, where necessary, disinfected. The Food Standards Agency's guidance on controlling E. coli O157, which also helps control salmonella and campylobacter, tells businesses how to do that in a real kitchen. Safer Food, Better Business puts the same expectation into safe methods a cook can follow on a Tuesday lunchtime: separate foods, separate equipment, wash hands, and clean as you go.

There is no single criminal offence written as "you used the wrong coloured board". Officers score what they see. A kitchen that can show raw food never meets food that will not be cooked again will have an easier visit than a kitchen with a laminated poster and a shared knife. The standard is the safe method you have written for this building, trained, and actually use. A copied paragraph that does not mention the one fridge, the one sink and the slicer by the pass will not survive the conversation.

Physical separation is the control the Agency prefers. Cleaning and disinfection between raw and ready-to-eat tasks is allowed when you cannot separate the work, and it carries the most risk. It is a method you have to do completely, every time, not a fallback you mention when the officer asks. If the team cannot describe the product, the contact time and who checks, you do not have that method. You have a hope.

What counts as raw, and what counts as ready to eat

Raw food, for this purpose, is food that can carry harmful bacteria and will normally be cooked or otherwise treated before it is eaten. Raw meat, raw poultry, raw fish and raw shellfish are the obvious group. Unwashed vegetables and salad, soil on potatoes, and the juices and packaging those foods arrive in belong with them. Eggshells are dirty even when the egg will be cooked. Raw flour and raw batter are not ready to eat either. People forget flour because it looks dry. Treat raw dough as raw until it has been properly cooked.

Ready-to-eat food will not get a cooking step that makes it safe before someone eats it. Cooked meats, sliced ham, sandwiches, washed salad and herbs, bread, cake, cheese, yoghurt, fruit prepared for a bowl, coleslaw, cooked rice for a cold salad, and garnishes all sit in that group. A cooked chicken breast is ready to eat the moment it leaves the pan, even though it was raw twenty minutes earlier. It does not go back on the raw board because it is "still chicken".

Write the awkward items into the safe method so staff do not invent an answer at the pass. Bacon for the griddle is raw until it is cooked through. A jacket potato that has been baked and is now being split and filled is ready to eat. Vegetables you will boil or roast are not ready to eat, but soil on them does not belong on the salad board. Washed lettuce is ready to eat. Unwashed lettuce is not. Pickles in a sealed jar are ready to eat once the jar is clean and the outside of the delivery box has stayed in the store. The outside of a raw chicken box is not a clean surface. It does not sit on the sandwich bench while somebody finds a pen.

Allergen separation is a different duty. A board kept for a nut-free job does not fix raw juices on a cake, and a perfect raw-and-ready split does not tell you whether the gravy contains milk. Keep both rules. The Natasha's Law guide covers the labelling side. This page is about bacteria moving from raw food onto food that will not be cooked again.

How contamination actually travels

Officers and the Agency use the same picture. Harmful bacteria move when raw food touches ready-to-eat food, or when they touch the equipment, cloth, hands or surface that then touch ready-to-eat food. The chicken does not have to sit in the salad bowl. A drip, a splash or a handle is enough. Campylobacter on poultry and E. coli on raw meat and on vegetables that have been in contact with soil are the examples that come up again and again. You cannot see them, and you cannot smell them.

• Direct contact. Raw mince in the same tray as sliced tomato. A cooked burger put back on the plate the raw burger left. Salad leaves dropped onto the raw board "for a second".
• Drips and leaks. Raw chicken on the top shelf of the fridge, uncovered or in a split bag, over cheesecake, ham or a bowl of custard. Defrosting meat in a colander with nothing underneath.
• Hands. Breaking eggs, then buttering toast. Handling raw sausages, then garnishing a plate. Washing hands in a hurry without soap, or wiping them on the apron and carrying on.
• Knives, boards, tongs and containers. The same knife for raw chicken and for cucumber. A tub that held raw mince, rinsed, then filled with cooked rice. Tongs that left the raw grill and picked up a bun.
• Cloths and aprons. One cloth for the whole kitchen. An apron that has leaned on the raw bench, then on the sandwich board. A tea towel used to dry hands and to dry a ready-to-eat knife.
• Sinks and splashes. Rinsing a chicken under the tap. Washing soil off potatoes in the same sink you then use for salad, without a clean and a disinfection between them. Spray from the raw area reaching open bread.
• Complex machines. A slicer used for raw bacon and then for cooked ham. A mincer or a vacuum packer used for both, with a wipe rather than a full dismantle and disinfection.
• Packaging and boxes. Outer boxes of raw meat on the ready-to-eat bench. A ready-to-eat bag of leaves opened on top of a raw tray. Re-using a raw meat container because it "looks clean".

Any one of those routes is enough to make the ready-to-eat food unsafe. The safe method has to close the routes you actually have, not a generic kitchen from a textbook. If you have one sink, the method is about that sink. If you have a slicer, the method is about that slicer. If you do not have a slicer, do not write a page about one.

Lay the kitchen out so the work stays apart

The Food Standards Agency describes separation in a clear order. The strongest control is separate rooms, with separate staff, utensils and equipment for raw and for ready-to-eat work. Next is separate areas in the same room, again with separate staff, utensils and equipment. If you cannot do either, you may use the same area for both, but only if you clean and disinfect it between the two jobs, and you follow the rules for that disinfection. The Agency is explicit that shared areas carry the most risk.

Most cafés, takeaways and small restaurants are in the second or third group. You will not build a second kitchen for this guide. You can still make the split obvious. Put ready-to-eat work at one end of the bench and raw work at the other. Keep the salad, the cooked meats and the cake away from the meat prep. Give each side its own boards, knives, trays and cloths, stored where that work happens so nobody walks across the kitchen to "borrow" the other set. Mark the areas in the safe method with the words your team use: "window bench is ready to eat, back bench is raw meat". A colour poster that nobody can match to the room is decoration.

Where the room is too small for two areas at once, separate the work by time. Prepare the ready-to-eat food first, while the benches are clean and before raw meat is unpacked. Then do the raw work. Or do the raw work, then stop, clean and disinfect every surface, utensil and sink you will need again, wash hands, change the apron, and only then start the sandwiches. Write the order down. "We play it by ear" is how a Tuesday rush puts raw bacon on the salad board. The same idea applies to a one-person shift. One person can do both jobs. They cannot do them with the same hands, the same cloth and the same board without a break for washing and cleaning.

Staff separation is the part small teams skip. The Agency's preferred picture includes separate staff where you can manage it. In a two-person lunch, that may mean one person stays on salads and plated food while the other stays on raw and the grill, and they do not swap without washing. In a one-person kitchen it means the sequence is the control: finish or pause the raw job, wash, change apron and gloves if you wear them, then move. Do not carry a raw tray in one hand and a plate of salad in the other.

Think about the route food takes, not only the bench. Raw meat from the back door should not travel across the sandwich section. Ready-to-eat desserts should not be stored on a shelf where raw boxes are stacked underneath. The bin for raw trimmings should not sit where salad is plated. Waste, packaging and dirty equipment have routes too. Draw them once, in the safe method, and check at the 4-weekly review that the room still matches the drawing. Kitchens drift. A new fridge in the wrong place undoes a careful plan.

Boards, knives and the rest of the small equipment

The Agency's catering advice is to use different chopping boards and knives for raw meat or poultry and for ready-to-eat food, unless that equipment can be heat-disinfected in a commercial dishwasher. Safer Food, Better Business says the same, and colour coding is how most UK kitchens make the rule visible to a new starter. The colours are not a statute. They work when your safe method names them and the team follows the sentence. A short code is better than a six-colour poster that nobody remembers. One set for raw meat and fish, another for everything ready to eat, is enough in a simple kitchen if you write it down and keep soil-covered vegetables off the ready-to-eat boards.

The detail of a practical colour code, what to do when a board is scored, and what to do when the wrong food hits the wrong board, is in the colour-coded chopping boards guide. Read it with this page. The point here is the rule behind the colours: raw equipment and ready-to-eat equipment do not mix, and a wash in warm water without a proper disinfection is not a change of identity for that board.

A commercial dishwasher, on a cycle the manufacturer rates for disinfection, is the heat option the Agency accepts for boards, knives and similar utensils. A splash in the pot-wash sink is not that cycle. A domestic short wash is not something to assume is hot enough or long enough. If you rely on the dishwasher, say so in the safe method, and do not put a board back into ready-to-eat use until that cycle has finished. "It is in the machine" means it is unavailable. Have a spare ready-to-eat board so the gap is not filled with the raw one.

The same logic covers tongs, trays, containers, probe thermometers, mixers and the handles people touch. A probe that has been in raw mince is not pushed into a cooked joint or a rice tray until it has been cleaned and disinfected. A plastic tub that held raw chicken is not a salad box because you rinsed it. Containers that are scratched and stained hold dirt the same way scored boards do. Replace them. Label raw containers if they are dedicated, and do not let ready-to-eat food travel in them even when they are empty and "look fine".

Slicers, mincers and vacuum packers

Complex equipment is where small kitchens get into serious difficulty. The Food Standards Agency's E. coli cross-contamination guidance says slicers, mincers and vacuum-packing machines should not be used for both raw and ready-to-eat food during a normal working day. If you change the machine from raw to ready-to-eat, it has to be dismantled and every surface cleaned and effectively disinfected. A wipe of the blade, or a cloth around the chamber, is not that job. Cooked ham sliced on a machine that has just cut raw bacon is a classic way to put raw contamination onto food that will not be cooked again.

The practical decision for most caterers is to dedicate the machine. If you slice cooked meats and cheese for sandwiches, that slicer is a ready-to-eat machine. Raw meat is cut by hand on the raw board, or on a different day only after a full strip-down that you can describe and that you have time to do before service. Vacuum packers need extra care. The Agency has separate notes on recommissioning them when their use changes, because the hidden parts are easy to miss. Do not decide in the middle of a Saturday that the cooked-meat packer can "just do" a batch of raw mince.

Write the rule where the machine is, not only in a folder. "This slicer is for cooked meat and cheese only" is a useful sentence. So is the name of the person who may strip it, and the product they use. If nobody on today's rota is trained to dismantle it, then today's rota does not include a change of use. That is a safer outcome than a confident wipe.

Storage order, including the fridge

Store raw food below ready-to-eat food, covered, so nothing can drip. Use a separate fridge for raw meat if you have one and the menu justifies it. In a single fridge the usual order is ready-to-eat food on the upper shelves and raw meat, poultry and fish in lidded containers on the bottom. Eggs stay in their box, not loose above a cheesecake. Open cans are decanted. Nothing is stored in a way that the next person has to rest a salad bowl on a raw tray to reach the milk.

Covering is part of the control. A tight lid, film or a clean container stops drips and stops ready-to-eat food picking up whatever is on the shelf above. It also stops strong raw smells being treated as the only problem. Smell is not the hazard. Juices are. Check the bottom of the raw container when you put it away. A split bag of chicken inside a clean box is fine. A split bag straight on the shelf is not.

Defrosting is storage with a time attached. Raw meat thawing in the fridge sits on the bottom shelf in a container deep enough to hold the liquid. It does not sit on a tray over cooked food, and it does not sit on the pass. The thawing guide covers the temperature side. The separation rule is the same on the way down from frozen as it is on delivery day: raw below, ready-to-eat above, no shared melt water.

Cold holding still applies while you do all of this. In England, Wales and Northern Ireland, food that needs chilling must be kept at 8°C or below, and the practical way to achieve that is to run the fridge at 5°C or below. Scotland should follow Food Standards Scotland and CookSafe, which set the same expectation of a cold fridge rather than a warm one you hope is "about right". A perfectly separated fridge at 12°C is still a failure. The fridge temperature log guide is the record that sits next to the shelf order. Officers look at both.

Dry storage has a quieter version of the same rule. Keep raw meat packaging out of the ready-to-eat dry goods. Do not stand a box of raw burgers on the shelf of buns, even for ten minutes while the fridge is being cleaned. Outer cardboard is often dirty and is a pest risk as well as a contamination risk. Unpack into the lidded box at the delivery point you have chosen, then take the cardboard out. The pest control guide is what you need when that cardboard starts to live in a corner.

Hands, gloves and aprons

Hands move bacteria as efficiently as a knife. Wash them before handling ready-to-eat food, after handling raw meat, poultry, fish or eggs, after touching bins or packaging, and whenever you change tasks. Use the basin, soap and a proper dry. The Food Standards Agency is clear that antibacterial gels do not replace washing. A gel on dirty hands is not a control. Gloves are not a substitute either. If you wear them, change them whenever you would have washed, and wash your hands when you change or remove them. The handwashing and gloves guide is the detail. What matters on this page is the moment: you do not leave the raw board and plate a salad on the same gloves.

Aprons and cloths are the other half of that moment. An apron that has been held against raw meat, or that has wiped a raw splash, should not be worn into the ready-to-eat job. Keep a clean apron for that work, or use a disposable apron for the raw task and take it off before you move. Do not dry your hands on the apron and then lean on the sandwich board. Cloths follow the areas. A cloth from the raw bench does not wipe the ready-to-eat bench, the fridge handle on the salad side, or the plates. Disposable paper for the raw clean-up is often simpler than a colour-coded cloth system you do not have time to run. If you do use cloths, say which cloth is for which area, how they are washed or thrown away, and check that the bucket is not one grey soup for the whole kitchen.

The basin has to be usable at the moment of the task. Hot water, soap and a way to dry hands that is not a dirty towel. It should be reachable from both jobs, or you accept the walk and you still do it. A basin full of utensils, or blocked by a delivery, is the same as no basin. Staff will not stop a service to excavate one. Opening checks should include the basin, not only the fridge.

Sinks, splashes and disinfection

Do not wash raw meat and poultry. Washing them spreads bacteria in droplets across the sink, the taps and the food nearby, and it does not make the meat safe. Cooking is what makes it safe. Safer Food, Better Business and the Agency both make that point because the habit is still common. If a recipe needs a rinse of a particular product, write why, where, and how you stop the splash. Do not leave it as a general permission to rinse chicken.

A sink used for raw food, including washing soil off vegetables or catching defrost liquid, is a raw sink until it has been cleaned and disinfected. Only then is it fit for ready-to-eat food or for equipment that will touch ready-to-eat food. If you can give raw vegetables and salad two different sinks, do that and write it down. If you have one sink, the safe method is the sequence and the disinfection, and you do not run them together. Handwashing stays at the hand basin. Food is not washed in the hand basin, and hands are not washed in the pot sink as the planned control.

Disinfection is a two-stage job on a dirty surface. First remove the food debris and wash with hot water and detergent so the surface is visibly clean. Then apply a disinfectant or sanitiser that meets an officially recognised standard, and leave it for the contact time the manufacturer prints on the label. The Food Standards Agency's E. coli guidance requires those chemicals to meet recognised standards and to be used as instructed. A combined sanitiser still fails if the surface is greasy or if you wipe it off immediately. Rinse afterwards if the product says to rinse, so you do not leave a chemical taint on food. Write the product name and the contact time in the safe method. "We use the green spray" is not enough when the bottle has been replaced with a different green spray.

Heat is the other disinfection route for equipment that can go through a suitable dishwasher or a proper heat treatment. It is not a cloth and a kettle. Surfaces that cannot go through a machine need the chemical route, done on a clean surface, for the right time. The cleaning schedule guide is where the daily and weekly jobs should live, including the bits under the slicer and the taps. Cross-contamination control fails when the visible bench is clean and the handle, the probe and the tap are not.

What to write in the safe method

Describe this kitchen. Name the areas, the fridge, the boards, the sink, the slicer if you have one, the chemical, and the order of work on a normal day. Say what staff do when the only ready-to-eat board is in the wash. Say that raw food is stored below ready-to-eat food, covered. Say that hands are washed between the two kinds of work, and that gels and gloves do not replace that wash. Say that complex machines are not dual-used in the same day.

Train people on that page, including Saturday staff and anyone who "only helps at the pass". The pass is where ready-to-eat food is finished. A person who wipes plates with the raw cloth can undo an hour of careful prep. Ask a new starter to explain the rule back to you before they work alone. A signature on a training sheet, with no conversation, does not tell you they know which board is which.

Record the exceptions in the diary, not a perfect week of ticks. If the wrong board was used, write what food you threw away, what you cleaned, and what you changed so it is harder next time. If a delivery of raw meat was left on the salad bench, write it even if you caught it before service. The 4-weekly review is where you look at those lines and decide whether the layout, the spare board or the staffing is the real fix. The corrective action guide is the shape of that note: problem, immediate action, and what will stop a repeat. The SFBB guide shows where the cross-contamination safe methods sit in the pack.

What environmental health officers check

Officers often watch a task rather than start with the folder. They look at where raw meat is, where ready-to-eat food is, and whether the person moving between them washes their hands. They open the fridge. They pick up a board and look at the colour, the scores and what is on it now. They ask what the slicer is for. They look at cloths, aprons, the sink and the basin. Then they compare that picture with the safe method.

• Whether raw meat, poultry and fish are covered and stored below ready-to-eat food.
• Whether boards, knives and containers for raw and ready-to-eat work are actually different, or are heat-disinfected in a dishwasher you can point to.
• Whether a slicer, mincer or vacuum packer is used for both in the same day, and whether anyone can explain a full clean if the use changes.
• Whether staff wash hands, and change gloves and aprons, when they leave raw work. Gels on their own do not pass this question.
• Whether the basin has soap, hot water and a way to dry hands, and is not blocked.
• Whether the disinfectant is suitable for food contact surfaces, and whether staff know the contact time rather than spraying and wiping at once.
• Whether raw food is being washed in a way that splashes ready-to-eat food or a sink that is about to be used for salad.
• Whether the safe method matches the room. A poster for a kitchen you do not have is a confidence-in-management problem.

A single dirty cloth can colour the whole visit, because it tells the officer the system is theoretical. So can a fridge that is tidy at the front and raw chicken over dessert at the back. You do not need a speech. You need the food in the right place, a cook who can say why, and a diary that shows what you did the last time it went wrong. The inspection checklist sets out the wider visit. Separation will not rescue missing temperature records, and perfect temperatures will not rescue raw meat over a cheesecake.

Worked example

A café serves a cooked breakfast and a lunch of ham sandwiches, salad boxes and cake. There is one kitchen, one fridge and two people on a weekday. The safe method says the window bench is ready-to-eat and the back bench is raw. Red boards and red knives are for raw bacon, sausages and any other raw meat. Green is for washed salad and fruit. Yellow is for cooked meat, including the ham for sandwiches. There is no slicer. Raw meat lives in a lidded box on the bottom shelf. Ham, salad and desserts are covered on the top shelves. The hand basin is between the two benches. The disinfectant is named in the pack, and the contact time on the bottle is written next to it. Ready-to-eat prep for lunch happens after breakfast raw meat is finished and the back bench has been cleaned and disinfected, or earlier in the morning before raw packs are opened. Nobody rinses bacon or chicken.

On a normal Wednesday the opener puts deliveries away before service: raw bacon in the bottom box, ham on the top shelf still in its sealed pack, salad leaves in a clean tub with the date. Breakfast uses the red board. When the grill is done, that board and knife go through the commercial dishwasher on the disinfection cycle. The cook washes their hands, changes the apron, and only then lays out bread and salad on the window bench. The diary has nothing to say about separation that day. The opening check says the fridge order was correct. That is a complete quiet day.

On Thursday the green board is still in the dishwasher at 11:30 and a lunch order needs cucumber. The breakfast cook, still in the raw apron, uses the red board because it is the one on the rack. The manager sees raw-board cucumber going into a salad box that already contains leaves and ham. They stop the job. The cucumber and the partly made salad box go in the waste. The red board, the knife and the window bench are washed and then disinfected for the time on the bottle. The cook washes their hands and changes the apron. The ham pack that stayed closed on the top shelf is still in date and was not touched, so it stays. The diary says: "Red board used for cucumber at 11:30. Salad box and cucumber binned. Bench, board and knife cleaned and disinfected. Hands washed, apron changed. Spare green board was in the office, not on the rack."

That afternoon they put a second green board on a hook by the window bench and add a line to the safe method: if the green board is in the wash, use the spare, do not use red. At the 4-weekly review they check that the spare is still on the hook and that Thursday's note is the only one of its kind. The cook who made the mistake is the person who explains the rule to the new Saturday starter. That is a working separation control, including the food they did not sell.

Common mistakes

• Storing raw meat above ready-to-eat food, or leaving it uncovered so juices can drip.
• Using one board and one knife for the whole menu because the kitchen is small.
• Rinsing a board under the tap and calling it disinfected.
• Wiping a slicer blade and then cutting cooked ham after raw bacon.
• Relying on gloves or a hand gel instead of washing with soap and water.
• One cloth, one apron and one spray bottle for raw and ready-to-eat benches.
• Washing raw chicken in the sink, then washing salad in the same sink.
• Putting delivery boxes of raw meat on the sandwich bench while you clear a shelf.
• A colour-code poster that does not match the boards you actually own.
• Ticks in the diary and a fridge that tells a different story.

Where this comes from

This guide follows the Food Standards Agency's advice on avoiding cross-contamination and the Agency's E. coli O157 cross-contamination guidance, including separation of areas and equipment, handwashing, and disinfection with products that meet recognised standards. It also follows the Safer Food, Better Business safe methods on separating foods, personal hygiene and cloths, and the underlying duties in assimilated Regulation (EC) No 852/2004. The Agency's Safer Food, Better Business for caterers pack is the working document for most English businesses. Scottish businesses should use CookSafe and Food Standards Scotland. Put your own rooms, equipment, chemicals and sequence into the safe method your team is trained on, and check at the 4-weekly review that the kitchen still matches the page.
