The new labels, developed together with waste reduction charity Wrap, will start appearing on bottles in a major UK supermarket next year.
The ‘thermochronic’ labels, which contain heat-sensitive ink, have been developed in response to research by Wrap which found households are throwing away 490 pints of unconsumed milk a year – an average of 18.5 per home.
Warm fridges are the most common reason for the waste, according to Wrap. A temperature of between zero and five degrees is recommended by the Food Standards Agency, but a typical UK fridge is two degrees warmer than this, Wrap claims.
The new labels will help consumers to recognise if their fridge is too warm.
Andrew Parry, a food and drink advisor at Wrap, said in a statement: “Making sure our fridges are running at the right temperature (below 5oC) could help reduce the amount of milk thrown away by more than 50,000 tonnes a year, saving householders at least £25 million.”
The group have also called for more people to freeze milk until they are ready to use it.
