'Use by' dates are soon to be a thing of the past as Morrisons are set to scrap them on the majority of its own-brand milk.
In a bid to reduce its food waste, the supermarket will instead place 'best before' dates on 90 per cent of its own-brand milk.
Recycling charity Wrap says Morrisons is the first supermarket to announce the move which could stop millions of pints of the own-brand milk from being thrown away every year.
The key sign that milk has been spoiled is a sour aroma and/or curdled consistency.
Ian Goode, senior milk buyer at Morrisons, said: “Wasted milk means wasted effort by our farmers and unnecessary carbon being released into the atmosphere.
“Good quality well-kept milk has a good few days life after normal ‘use by’ dates – and we think it should be consumed, not tipped down the sink.
“So, we’re taking a bold step today and asking customers to decide whether their milk is still good to drink.
“Generations before us have always used the sniff test – and I believe we can too.”
Marcus Gover, of Wrap, said: “I am delighted that Morrisons is the first UK supermarket to take this important step to help reduce household food waste – it shows real leadership and we look forward to more retailers reviewing date labels on their products and taking action.”
