Is food really dead the second its date passes?

That date on the box is two completely different promises, and only one is about your safety.

'Best before' marks quality, not safety - it is the date a food stops being at its best, but it is usually fine to eat after. 'Use by' is the safety line: past it, the food can actually make you sick. Eggs, yogurt, crackers, and dry pasta carry 'best before' and are mostly fine for days or weeks past the date. Fresh meat, fish, and ready meals carry 'use by' - respect those.

You find a pack of biscuits in the cupboard stamped 'best before' last week. Toss it and you just threw away good food and your money - it is stale at worst, not dangerous.

'Best before' = peak quality (still edible after). 'Use by' = safety (do not eat after). Read which one is printed before binning anything.

Knowing the difference saves real money and cuts the food you waste every week, instead of binning perfectly good groceries on a date that was never about safety.

Best before = best taste. Use by = use or you risk it.
