The Co-op is to remove best before dates from many fruit and vegetables in a bid to reduce food waste.
The company said taking the dates off its fresh produce would help shoppers save money and help the environment.
It said food stored in the fridge would keep for much longer than best before dates indicated.
Bigger national supermarkets, including Sainsbury's and Asda, made similar moves last year.
From next week, the Co-op will remove best before dates from more than 150 fresh products, including apples, broccoli, carrots, onions, oranges, potatoes and tomatoes.
A small number of more perishable products will still have best before dates.
The move follows a trial last year on 20 products.
The Co-op group, which has 2,500 UK grocery stores, will instead use encrypted codes - a series of letters and numbers - for workers in stores to keep track of how long produce has been on the shelf.
It said that best before dates on fresh produce could mean people threw fruit and veg away when it was still good to eat.
It said customers should use their judgement as to whether fresh fruit and vegetables at home had gone off.
