FIFO Food Storage at Home: A Simple Guide for UK Kitchens

Isometric illustration of FIFO food rotation

FIFO stands for first in, first out. In a home kitchen it means the food you bought earliest, or the food with the soonest date, sits at the front and gets used first. Newer food goes behind it. That’s the whole idea, and it works in the fridge, the freezer and the cupboard.

The method comes from commercial kitchens and warehouses, but you don’t need labels, spreadsheets or a clipboard to use it. You need about five minutes after each shop and a few habits. This guide shows you how, and where dates and fridge temperatures fit in.

TL;DR

  • FIFO means older food goes to the front and new shopping goes behind it, so the oldest items are seen and eaten first.
  • Unpack your shop in the same order every time: check dates, move old stock forward, then slot the new items in behind.
  • Give yourself an “eat me first” shelf in the fridge and a spot in the cupboard for anything open or close to its date.
  • Use-by is about safety and best-before is about quality, so they are not the same signal. Keep your fridge at 5°C or below.
  • An app can take over the remembering: we built Ask the Kitchen to track what you have and suggest meals that use it up first.

What does FIFO mean in food storage?

FIFO is a stock rotation system. Love Food Hate Waste recommends it for households: when you unpack groceries, put newer items behind older ones in the fridge, pantry or freezer, so you use what you bought first and cut the chances of food running out of date.

The opposite is what most of us do by accident. New shopping goes on top or at the front because it’s the easiest place to reach. The older tin, the half-used bag of rice and the yoghurt from last week slide to the back and wait there. By the time you find them, they are past their date, and you’ve paid for food that went in the bin.

FIFO fixes this with one simple rule: what’s been in longest is what you can see first.

A quick note on the phrase. You’ll also see it written as “first in first out”, and some people use “FEFO”, meaning first expired, first out. At home the two are close to the same thing. If a newer item has a sooner date than an older one, the sooner date goes in front. Dates beat purchase order.

What does FIFO mean in food storage?

How does first in, first out work in a real kitchen?

Here’s the routine, from the moment the shopping comes through the door.

  1. Empty the shelf space first. Pull the older items forward and take a quick look at their dates.
  2. Put the new items at the back. Fridge, cupboard or freezer, the newer food goes behind or underneath.
  3. Check the date, not just the order. If the new pot of cream has an earlier date than the old one, swap them.
  4. Move anything open or near its date to the front. That includes open jars, half packs and soft fruit.
  5. Tidy as you go. Wipe the shelf, throw away anything that is clearly past it, and note what you need to eat soon.

Climate Action Wales gives the same advice: check product labels before you store food in cupboards, the fridge and the freezer, and move older foods to the front of shelves so you can use them first.

It feels fussy for the first couple of shops. After that it becomes automatic, a bit like putting the milk back in the fridge.

How do you use FIFO in the fridge?

The fridge is where FIFO pays off fastest, because it holds the food that goes off quickest.

Set up an “eat me first” shelf

Love Food Hate Waste suggests creating an “eat me first” shelf for food that’s close to the end of its life. It sits at the front, where it’s easy to see, rather than hiding at the back. Good candidates are:

  • open jars and sauces
  • leftovers
  • opened packets of crackers or ham
  • cheese close to its date
  • fruit and veg that are starting to soften

If you want the longer version of this habit, our guide to keeping your fridge from becoming a graveyard goes shelf by shelf.

Keep it cold enough

FIFO only works if the food in the fridge is stored safely. Food Standards Agency guidance says that setting your fridge to 5°C keeps food at 8°C or below. That is a legal requirement for food businesses in England, Wales and Northern Ireland, and recommended in Scotland. Love Food Hate Waste also says to check your fridge is below 5°C.

It’s worth checking with a cheap fridge thermometer, since many home fridges run warmer than people think. When the FSA’s chief executive spoke about the cost of living in 2022, she said that keeping the fridge at 5°C or below stops bacteria multiplying and helps food last as long as it can. She also warned against switching the fridge off to save money.

Don’t pack the fridge too tightly either. Climate Action Wales says to keep shelves organised and not too crowded so air can circulate and the temperature stays steady. That is a useful limit on FIFO: you’re rotating food, not cramming it.

Where each thing goes

A few quick placement rules help the rotation make sense:

  • Raw meat and fish go on the bottom shelf so nothing drips onto other food.
  • Milk and dairy go on a shelf, not in the door, which is the warmest part.
  • Salad and leafy greens go in the crisper drawer.
  • Cooked and ready-to-eat food goes above raw food, so it’s safe from drips.

Love Food Hate Waste also suggests keeping the fruit bowl in the fridge, apart from bananas and uncut pineapples, which helps fruit last longer.

How do you use FIFO in the freezer?

The freezer is your pause button, and FIFO makes sure it doesn’t turn into a mystery drawer.

  • Label and date everything. A marker pen and masking tape are enough. “Chilli, 12 Nov” beats “brown stuff”.
  • Freeze in portions. Health Well advises dividing meals into portions before freezing, then defrosting only what you need, which cuts waste.
  • Newest at the back or bottom. Same rule as the fridge. Older bags and tubs come forward.
  • Freeze early, not late. Love Food Hate Waste suggests freezing food when you get home if you know you won’t need it until later in the week.

Bread is the classic example. Climate Action Wales notes that UK homes throw away 20 million slices of bread a day, and suggests freezing it for up to six months or turning it into breadcrumbs or croutons. Sliced bread you pull out one piece at a time is a very easy first FIFO win.

If you cook for someone who needs softer textures, batches of portioned meals suit the freezer well. These pureed food ideas for carers give you meals worth cooking in bulk and rotating through the freezer.

Our freezer-first shopping guide shows how to plan shops around what’s already in there.

Defrosting and leftovers safely

FIFO is about order, not about stretching food beyond safe limits. Health Well advises that frozen raw food can be defrosted once and kept in the fridge for up to 24 hours before it needs to be cooked or thrown away. Cooked food that’s been frozen should be reheated and eaten within 24 hours of fully defrosting.

For leftovers going into the fridge, the FSA advises cooling them within one to two hours, then fridging or freezing them and using them within 48 hours. Smaller portions cool faster. When you reheat, Health Well says to heat food until it reaches 70°C for 2 minutes, so it is steaming hot all the way through.

Safe cooling, storage and reheating times for leftovers

How do you use FIFO in the cupboard or pantry?

The “first in first out pantry” is the easiest to set up, because dry goods are forgiving and you can see everything at once.

  1. Take everything out once. Group like with like: tins, pasta and rice, baking, sauces, snacks.
  2. Bin or use what’s clearly past it. Check the dates and the packaging.
  3. Put the soonest dates at the front. Use the shelf’s depth: old at the front, new behind.
  4. Write the date big on loose items. Decanted flour, rice or lentils lose their label, so mark the date on the container.
  5. Keep an open-first spot. Opened packets of crackers, half bags of pasta and the last of the cereal go in one place.

If stacking tins feels awkward, put them in rows by type, with the oldest at the front of each row. Some people use a tin dispenser, but a shoebox on its side does the job.

Once your shelves are in order, it’s much easier to shop from them. We cover that in shop your pantry first and how to shop your own cupboards before the shops. If you’re unsure what a well-stocked cupboard looks like, our pantry staples list breaks it into six categories.

A rotation rhythm that sticks

You don’t need to do everything every day. A simple pattern is enough:

When What to do
After every shop Move old to the front, put new behind, refresh the “eat me first” shelf
Weekly Glance at the fridge, plan meals around what needs using
Monthly Check the cupboard and freezer for foods nearing their dates
Every few months Look deeper in storage for forgotten items, damp or damaged packs

This follows the same logic as stock rotation routines recommended for long-term storage, with checks on a monthly and three-monthly rhythm, scaled down for an ordinary family kitchen.

Use-by or best-before: which comes first?

Dates are the tie-breaker in FIFO, so it’s worth knowing what they mean. They don’t mean the same thing.

  • Use by is about safety. The WRAP labelling guidance says it relates to food safety, and food can’t be sold, redistributed or eaten after it. It’s applied to highly perishable foods.
  • Best before is about quality. The same guidance says the food can still be sold and eaten after this date, as it’s about the period the food can be expected to keep its best condition.

Love Food Hate Waste puts it simply too: getting date labels right can save you money by stopping you binning food in error.

Most people know the basics. The FSA’s Food and You 2 survey found that 65% of respondents identified the use-by date as the sign food is no longer safe to eat, and 64% said they always check use-by dates before cooking.

In FIFO terms, that gives you an order:

  1. Use-by dates coming up soonest go at the front, and into tonight’s or tomorrow’s meals, or into the freezer.
  2. Opened items and leftovers come next.
  3. Best-before items follow, and you judge them by look, smell and quality.

Also follow the storage instructions on the label. Food kept warmer than the label says can be unsafe before its date. For a deeper look, read our guide on use-by vs best-before and the 48-hour rule.

This matters most when money is tight. An FSA survey reported by The Guardian found that 32% of respondents had eaten food past its use-by date at least once in the past month because they couldn’t afford to buy more. FIFO helps here because it makes sure the food reaches the table before the date, not after it.

What FIFO mistakes cause waste?

The method is simple, but a few habits undo it.

  • Rotating once, then never again. The fix is to make it part of unpacking, not a one-off tidy.
  • Hiding the “eat me first” food. If it’s behind the milk, it isn’t first. Put it at eye level.
  • Overstuffing the fridge. Air needs to move, as Climate Action Wales points out.
  • Forgetting the freezer. Frozen food that nobody can identify will not get eaten. Label it.
  • Buying doubles. Love Food Hate Waste advises you to take stock of what you have before writing a list, then stick to the list. Otherwise you’re rotating two tins of tomatoes you didn’t need.
  • Treating dates as the only test. Dates are a guide. Storage temperature and how the food has been handled matter too.

Our view: FIFO is only half the job

Rotating your shelves is a great habit, and we’d encourage everyone to do it. But we see where it falls down in busy homes. You can put the oldest food at the front and still not know what to cook with it.

That’s the gap we built Ask the Kitchen to fill. Instead of starting with a recipe and shopping for it, we start with the ingredients in your kitchen. You scan barcodes or add items by hand, and we track stock and quantities across the fridge, freezer and cupboard.

Then we do the part that FIFO leaves to you. We factor in use-by dates, allergies and dislikes, prioritise the food that needs eating first, and suggest meals that need as little extra shopping as possible. When you cook a meal, the stock reduces automatically, so your inventory stays honest without extra admin.

Our aim is simple: less food thrown away, less money spent, and one less “what’s for dinner?” argument at 5pm. FIFO gives you the order, and we help you turn it into a meal.

FAQ

What does FIFO mean in food safety?

FIFO means first in, first out. You store older food, or food with the soonest date, in front and use it before newer food behind it. It cuts the chance of food going out of date unnoticed. It’s a rotation habit, so you still need to store food at the right temperature and follow label instructions.

What is a FIFO fridge?

It’s a fridge organised so the oldest and soonest-dated food is at the front and the newest is at the back. Many people add an “eat me first” shelf for open jars, leftovers and soft fruit. Keep the fridge at 5°C or below and don’t overfill it, so air can circulate.

How do I do first in first out in a pantry?

Take everything out, check dates, and put the soonest dates at the front of each shelf. Slot new shopping behind. Write dates on any decanted food and keep one spot for opened packets. Repeat the quick version every time you unpack a shop.

Should I always use the oldest food first?

Not always. Date comes before purchase order, so a newer item with an earlier use-by date goes first. Use-by dates are about safety, so those foods need eating or freezing by the date. Best-before foods are about quality, so you have a bit more flexibility.
