Global NGO WRAP has challenged the way retailers sell fresh uncut fruit and vegetables, following an 18-month project conducted with input from industry.
The research, which examined the link between food waste in the home and the use of plastic packaging, challenges accepted thinking that packaging helps to preserve fresh produce.
In fact, it shows that selling loose has huge potential to reduce food waste in our homes.
The research also examined the influence of date labels and storage temperatures on food going to waste.
WRAP is now calling on the UK’s major retailers to rethink how they sell uncut fresh produce.
It recommends that retailers sell loose, where possible, unless it is shown that plastic packaging reduces overall food waste.
The NGO is also calling for date labels to be removed unless it can be shown that a Best Before reduces overall food waste.
Retailers are also being advised to help customers understand the benefits of storing appropriate fresh produce in the fridge, below 5°C, at home.
‘This important research could be a game-changer in the fight against food waste and plastic pollution. We have demystified the relationship between wasted food, plastic packaging, date labels and food storage. While packaging is important and often carries out a critical role to protect food, we have proven that plastic packaging doesn’t necessarily prolong the life of uncut fresh produce. It can in fact increase food waste in this case. We have shown the massive potential to save good food from being thrown away by removing date labels.
‘We are all living with the reality of the climate emergency and the rising cost of living. This new clarity could not be more timely. We need retailers to step up and follow our recommendations so we can achieve real progress in tackling food waste and plastic pollution. This helps save the planet and us money at the same time – a real win-win.’

WRAP tested five commonly wasted items (apples, bananas, broccoli, cucumber and potatoes) stored in the original packaging and loose and at different temperatures.
The charity found that selling the five loose and removing Best Before dates could result in a combined saving of around 100,000 tonnes of household food waste, more than 10,300 tonnes of plastic and 130,000 tonnes of CO2e.
This saving comes from both enabling people to buy the right amount for their needs (potatoes, bananas and apples) and to use their judgement to decide when items are still good to eat.
While most supermarkets already sell some items loose, the new research presents compelling evidence for significantly increasing the practice across a wide range of fresh fruit and vegetables.
‘Finally some sanity in the crazy nanny-state world of food retailing. Six years ago, we launched the Plastic Free Aisle in Amsterdam. That’s six years of feet-dragging from UK supermarkets, continuing to default to plastic to wrap fruit and vegetables that Nature already gave a protective layer.
‘Finally we call out the billions of plastic sachets that infect our environment. Finally people can buy what they want rather than the multipacks they are sold. And finally we can see the madness of best before and consume by labels that tell us nothing our noses don’t already know and contaminate food waste and compost.’

The research also confirmed a point WRAP has long promoted: that uncut fresh produce can be good to eat long after the Best Before date and most lasts longer in the fridge.
When stored at 4°C, apples, for example, showed no signs of deterioration until two and a half months after their Best Before date and were still good to eat for some time after that.
Broccoli showed no signs of deterioration until more than two weeks after the Best Before date.
These new findings have prompted WRAP to reiterate its call (made in 2019) for the removal of Best Before dates from fresh uncut produce wherever possible.
The results of WRAP’s work have been shared with UK’s largest food retailers, along with the key recommendations.
Whilst keen for its recommendations to be implemented, the charity acknowledges that this move is likely to take time and requires the whole sector to work together – and bring citizens on the journey, too.
In the coming months, WRAP will continue to consult with the Food Standards Agency, Defra and industry over the recommendations as well as updating Best Practice guidance, and to develop a pathway for more fresh uncut produce to be sold loose.
Alongside the research is an updated list of the key plastic items for UK Plastics Pact members to remove as far as possible by the end of 2022. The additional items are:
Plastic packaging for uncut fresh fruit and vegetables, unless demonstrated to reduce food waste, has been added to the list as a longer term goal.
Since 2018 when The Pact was launched, members have reported a 46% progress in reducing specific problematic plastic items and a 10% reduction in plastic packaging overall.
