Use-By vs Best-Before vs Sell-By: What Food Dates Actually Mean

A staggering amount of perfectly good food gets thrown out for one silly reason: people treat every date on the packaging as a hard deadline. It isn't. The labels mean different things, and only one of them is about safety.

Use-by = safety

A use-by date is the important one. You'll find it on perishable, higher-risk foods like meat, fish, dairy and ready meals. After this date, the food may not be safe to eat even if it looks and smells fine — so don't push past it.

The one habit that helps: store these foods properly and eat or freeze them in time. Freezing on the day of purchase effectively pauses the clock.

Best-before = quality

A best-before date (sometimes "best if used by") is about quality, not safety. After it, the food is usually still perfectly fine to eat — it just might have lost a little crunch, colour or flavour. Dried pasta, canned goods, crackers and many condiments can be good for a long time afterward.

The rule here is simple: trust your senses. If it looks, smells and tastes right, it almost certainly is.

Sell-by = for the shop

A sell-by date is really a note to the store about how long to display an item. As a shopper, you can usually count on several more days at home after a sell-by date, assuming you've stored it well.

Don't guess — check

Not sure how to read the date in front of you? The Use-By vs Best-Before checker tells you what a given label means and whether the food is likely still good. And for a sense of how much longer something keeps, the Food Shelf Life Calculator gives typical timelines.

Let the dates come to you

Squinting at tiny labels in the fridge is nobody's idea of fun. PantryKit records the date for each item you add — or estimates one for you — and quietly reminds you before it's due, so you use food at its best and waste far less of it.
