Use by and best before
Use by
You will see "use by" dates on food that goes off quickly, such as smoked fish, meat products and ready-prepared salads.
Don't use any food or drink after the end of the "use by" date on the label, even if it looks and smells fine. This is because using it after this date could put your health at risk.
For the "use by" date to be a valid guide, you must follow storage instructions such as "keep in a refrigerator". If you don't follow these instructions, the food will spoil more quickly and you may risk food poisoning.
If a food can be frozen its life can be extended beyond the "use by" date. But make sure you follow any instructions on the pack, such as "freeze on day of purchase", "cook from frozen" or "defrost thoroughly before use and use within 24 hours".
Once a food with a "use by" date on it has been opened, you also need to follow any instructions such as "eat within three days of opening".
But remember, if the "use by" is tomorrow, then you must use the food by the end of tomorrow, even if the label says "eat within a week of opening" and you have only opened the food today.
Best before
"Best before" dates appear on a wide range of frozen, dried, tinned and other foods.
Except in the case of eggs, "best before" dates are about quality, not safety. When the date is passed, it doesn't mean that the food will be harmful, but it might begin to lose its flavour and texture.
Every year in the UK we throw away 8.3 million tonnes of food and drink, most of which could have been eaten. So think carefully before throwing away food past its "best before’" date.
However, you shouldn't eat eggs after the "best before" date. This is because eggs can contain Salmonella bacteria, which could multiply to high levels if you keep them after this date.
Remember, the "best before" date will only be accurate if the food is stored according to the instructions on the label, such as "store in a cool dry place" or "keep in the fridge once opened".
Display until and sell by
Date marks such as "display until" or "sell by'"often appear near or next to the "best before" or "use by" date. These are instructions for shop staff , not for shoppers.
The important dates for you to look for are the "use by" and "best before" dates.
