Tesco will sell unwashed potatoes for the first time in 40 years in a bid to reduce food wastage.
Shoppers at 262 of the supermarket giant's 2,650 stores can now buy spuds as nature intended from the Branston organic range.
The logic behind selling potatoes with soil is it helps to block out light and slow down decay and could extend usability dates from five days to 11.
Customers will not however receive fewer spuds in the bag, as Tesco said it has taken soil into account and adjusted the weights accordingly. Rob Hooper, from Tesco, told The Sunday Times: "Up until about 50 years ago, potatoes would generally be sold unwashed, and having a natural film of soil around them would help keep them fresher for longer.
"At the end of the 1970s, supermarkets and greengrocers moved towards selling more cosmetically perfect produce, and as a result, potatoes were washed before being put out on display."
Waste action group Wrap welcomed the move, adding that unused potatoes were one of the most likely foods to be thrown away each week. Will McManus, Wrap's sector specialist for fresh produce, said: "Wasting household food makes a huge contribution to global emissions, with 70 per cent of food waste, outside farms, coming from the home."
Other foods most likely to be wasted by households include bread, milk, bacon, chicken and carrots.
Last week, Tesco responded to investors calling for it to boost sales of healthy food and drink amid growing evidence that the UK’s obesity problem has worsened during the Covid-19 pandemic and on Friday announced it had committed to a “major new programme of reformulation” to improve the health profile of its products by 2025.
