What the Dates on Food Labels Actually Mean, Explained

The dates printed on food are among the most misread pieces of information in any kitchen. People throw away perfectly good food because a date has passed, while occasionally trusting something they should not. The confusion is understandable, because the labels look similar but mean very different things, and only one of them is really about safety.

A use-by date is the important one. It appears on perishable, higher-risk foods such as meat, fish and ready meals, and it is about safety, not quality. Eating these foods after their use-by date can genuinely make you ill, even if they look and smell fine, because harmful bacteria may have grown to unsafe levels without any obvious sign. This is the date to respect strictly, and freezing before it is a good way to extend the window.

A best-before date is about quality, not safety. It tells you when the food is at its peak, after which it may gradually lose flavour, texture or crispness but is generally still safe to eat. Dried pasta, tinned goods, biscuits and many store-cupboard staples remain perfectly usable well beyond their best-before date. Here your own senses are a reasonable guide, and a great deal of edible food is binned needlessly because people treat this date as a hard deadline.

Sell-by or display-until dates are aimed at the shop, not you. They help staff manage stock rotation and have little to do with how long the food is good for at home. You can generally ignore them, focusing instead on the use-by or best-before date, whichever the product carries.

The practical takeaway is simple: treat use-by as a safety limit and best-before as a quality guide. Storing food correctly, keeping the fridge cold enough and freezing what you cannot eat in time all stretch these windows further. Understanding the labels is one of the easiest ways to cut both your food bill and your waste.
