Reducing Food Waste: What To Do
Buying, storing and using food so that less of it is thrown away.
Last revised
UK households throw away a substantial share of the food they buy, which is the same as throwing away part of the food budget.
Key takeaways
- Use-by date: a safety date; do not eat after it
- Best-before date: a quality date; food is usually safe after it
- Most useful single change: Keep the fridge at 5C or below and check it with a thermometer.
- Commonest mistake: Eating anything past its use-by date.
- See a doctor if any of the signs under "When to get help" below apply to you.
Do
- Keep the fridge at 5C or below and check it with a thermometer
- Freeze bread and milk, both of which freeze well
- Plan meals around what needs using first
- Store fruit and vegetables as the packaging advises
Do not
- Eating anything past its use-by date
- Overfilling the fridge, which stops cold air circulating
- Confusing best-before with use-by

When to get help
Never eat food past its use-by date, and never refreeze food that has been thawed unless you have cooked it in between. Contact NHS 111 for vomiting or diarrhoea lasting more than a couple of days, blood in stool, or signs of dehydration.

How this page was put together
Every figure, recommendation and warning above is taken from the guidance named in Where this comes from. Nothing on this page is inferred, summarised or generalised beyond what those bodies publish: where they give a number, it is their number, and where they are silent, so are we. Pages are rebuilt whenever the underlying record changes. Sign-off by a named clinician, where it has happened, is shown at the top of the page along with the date.
