Can You Eat Frozen Food After Its Use-By Date?
Reviewed against FSA date labelling guidance · Updated September 2026
Nutritional data sourced from USDA FoodData Central and Public Health England. Always consult a registered dietitian for personal dietary advice.
Frozen food is safe indefinitely at -18°C — the best-before date marks when quality (texture, flavour) starts declining, not when it becomes unsafe.
Use-by vs best-before — which does this food carry?
At -18°C bacteria cannot grow, so continuously frozen food never becomes unsafe with time — freezer dates are pure quality guidance, marking when freezer burn and texture loss start to show. The safety questions with frozen food are all about the edges of freezing: was it frozen before its use-by date, and is it defrosted safely (in the fridge) and used within 24 hours?

Common questions
How long after the best-before date can I eat frozen food?
There's no fixed cut-off — it depends on storage. Days to weeks is common for frozen food; long-life products can be fine months later. Judge each item by condition, not the calendar.
What signs mean frozen food should be binned?
Visible mould, an off or sour smell, rancid taste, or pest damage. Any of those overrides everything else.
Why does frozen food get a best-before rather than a use-by date?
Because it doesn't support the growth of dangerous bacteria — it deteriorates in quality rather than becoming hazardous. Use-by dates are reserved for high-risk perishable foods.
Does proper storage extend it?
Considerably. Kept cool, dry and sealed, frozen food will hold its quality well past the printed date; stored badly, it can decline before the date.
