A best before date is a food date mark that mainly relates to quality. It tells you how long a food is expected to keep its best taste, texture or appearance when it has been stored correctly. Food may still be safe to eat after this date, but its quality might have changed. This is different from a use-by date, which is about safety. Understanding this key terminology helps you explain food labelling, storage and food safety accurately in WJEC Level 1/2 Hospitality and Catering or AQA GCSE Food Preparation and Nutrition answers.
What does a best-before date mean?
A best-before date is the date until which a food is expected to be at its best quality. Quality means the features people notice when eating food, such as flavour, smell, texture and appearance.
After the best-before date, the food may not be at its best, but it may still be safe if it has been stored correctly and the packaging is undamaged. For example, dry foods such as cereal, rice or pasta may gradually lose quality after their best-before date, even though they might remain suitable to eat.
Best before date and use-by date
| Date mark | Main meaning | Revision point |
|---|---|---|
| Best before | Quality | Food may still be safe after the date if stored correctly, although its quality may have declined. |
| Use by | Safety | Follow the date and storage instructions carefully. Do not treat it as simply a quality guide. |
This distinction is important in an examination. Do not write that all food is unsafe after a best-before date. Equally, do not confuse a best-before date with a use-by date. Always read the wording on the packaging and follow any storage instructions, such as keeping a product in a cool, dry place or refrigerating it after opening.
How does storage affect the date?
The date assumes that the food has been stored as the manufacturer states. If a packet says to keep food dry, damp storage could affect its quality. If a food needs refrigeration after opening, leaving it at room temperature may make it deteriorate more quickly. The condition of the packaging also matters. A damaged, leaking or swollen pack should not be treated as normal simply because the printed date has not passed.
For a food with a best-before date, a responsible check may include looking at the packaging and considering the food’s quality. However, appearance or smell alone cannot prove that every food is safe. A best-before date must never be used to override a use-by date or clear storage instructions.
Exam-ready summary
- A best-before date is a quality date.
- After this date, food may still be safe if it has been stored correctly.
- Its taste, texture, smell or appearance may have deteriorated.
- A use-by date is different because it relates to safety.
- Storage instructions and packaging condition must be considered.
- Do not claim that food is automatically unsafe after a best-before date.

Question: What is the main difference between a best-before date and a use-by date?
Answer: A best-before date is mainly about quality, while a use-by date is about safety. Food may still be suitable after a best-before date if it has been stored correctly, but the quality may have declined.
Food labelling and safety guidance can change. For the specification context, consult the relevant WJEC specification or AQA specification. For current practical guidance, check the relevant official Food Standards Agency, NHS or GOV.UK information.
