0 of 6 doneHow long does tinned food last? Start with the date on the tin
Most tins show a best before date on the lid or base. It is the maker's view of how long the food will be at its best. It is not an expiry date, and it does not mean the food turns unsafe the next day.
A use by date is different. It is about safety, so never eat food after it. Tins rarely carry one, but check. Our guide to best before and use by explains the difference in full.
Check the tin, not just the date
A date tells you what the maker expects. The tin tells you what has happened since. As our reasonable practice, bin any tin that is:
- Bulging or puffed at the ends
- Leaking, sticky or damp at a seam
- Deeply dented, especially along a seam or rim
- Rusted through or flaking, rather than lightly marked
When you open one, throw the food away if it spurts, smells off or looks wrong. If you are in doubt, throw it out. Use a manual tin opener (Retailer link coming soon) that cuts cleanly, and mind the sharp edge on the lid.
Where to keep tins
A cool, dry cupboard is best. Damp is the enemy, because it lets tins rust. A garage or shed can be too damp, and the shelf above the cooker or boiler can be too warm. Keep tins off the floor if you can.
A simple rotation habit
Rotation means using the oldest tin first and replacing it with a new one, so nothing sits unnoticed for years. It takes a minute a week.
- Label. Write the month you bought it on the tin with a marker, or use date-label stickers (Retailer link coming soon).
- Order. Put new tins at the back and the oldest at the front.
- Use. Cook with the front tin, then buy one to put at the back.
- List. Keep a simple note of what you have. A pantry inventory notebook (Retailer link coming soon) will do, or follow our pantry inventory template.
Buy tins you already like. A multipack of tinned beans (Retailer link coming soon) is a cheap place to start if your household eats them. Our guide to organising a pantry goes deeper, our view on food rotation explains why a small stock you rotate beats a large one you forget, and our no-cook food list has ideas.
Do this today (free)
- Take every tin out of the cupboard and read the date.
- Bin any that are bulging, leaking or badly rusted.
- Put the oldest at the front and eat those first this week.
If you have £10
This is a budget, not a quote. Prices change, so check the current price first. About £10 buys a marker or labels, plus a manual tin opener if yours is stiff.
Questions people ask
Is tinned food safe after the best before date?
Often, yes, but check the tin first. Food Standards Agency guidance says best before is about quality, not safety, so food past that date may be less tasty rather than unsafe. Throw away any tin that is bulging, leaking or badly dented, and never eat food past a use by date.
How can I tell if a tin has gone bad?
Look before you open. Bin tins that are bulging, leaking, rusted through or deeply dented, especially along the seams. When you open one, throw the food away if it spurts, smells off or looks wrong. This is our reasonable practice, and if you are in doubt, throw it out.
How long does tinned food last once opened?
Not long, and the label is the best guide. Follow its instructions for storing leftovers. As our reasonable practice, move leftovers to a clean, covered container, chill them promptly and use them up quickly. If you are unsure how long food has been open, throw it away.
Where is the best place to store tinned food?
A cool, dry cupboard away from damp, steam and heat. Avoid damp garages and sheds, where rust can start, and the spot right above the cooker or boiler. Keep tins off the floor if you can, and put new ones behind the older ones so you eat the oldest first.
