While British shoppers are facing rationing over iceberg lettuce and courgettes, supermarket shelves in Spain are overflowing with vegetables.

Shoppers in the UK are being stopped from bulk-buying vegetables such as broccoli, aubergines and tender heart cabbages due to a growing fresh produce shortage.

The shortage is being blamed on extreme weather that has devastated crops in Spain.

But despite the empty shelves across Britain, supermarkets in Spain are displaying an abundance of fresh vegetables.

The rationing in the UK comes amid reports of panic buying in response to a growing fresh produce shortage that has left shelves empty across Britain.

Asda's customers will not be able to buy more than six of each item at its 525 outlets.

Several supermarkets have also decided to block online sales of many vegetables and salads to ensure they have enough stock for their high street stores.

Droughts followed by storms, floods and snow, has had a devastating impact on crops across the Mediterranean farming belt.

This has caused a shortage of lettuce, broccoli, courgettes and other ingredients, which could last for months and is driving up prices. The crisis has been exacerbated by restaurants and caterers raiding stores after their wholesale suppliers ran out.

The Daily Mail revealed yesterday how Tesco is limiting customers to buying a maximum of three iceberg lettuces. Morrisons is also rationing store customers to a maximum of three – two in some places – and three heads of broccoli.

Now Asda is to stop people buying any more than six of five key vegetables. A spokesman said: 'We have taken the decision so that individual customers are able to get hold of their favourite veg.

'A run of unusually bad weather has resulted in availability issues … We're doing everything we can to support our growers and get back up to full supply as quickly as possible.'

Other retailers, including Ocado online, are considering rationing and the Co-op has asked customers not to bulk-buy.

But yesterday at a Sainsbury's in Southampton which warned about the low availability of lettuce, customer Wendy Smith, 67, said: 'The shelves for one type of lettuce only had two left. I think it is people panic-buying.'

Supermarkets are also trying to conserve supplies of vegetables and salad for their bricks-and-mortar branches by removing them from online stores.

A long list of fresh products were 'not available' on the Tesco website yesterday – no whole cucumbers, organic and tender stem broccoli, beef tomatoes, aubergines, pak choi or spinach. Many bagged salads were also unavailable.

A spokesman said: 'Our priority is to keep the shelves in stores stocked. If supplies fall below a certain level our systems make sure the products we do have go to the stores ahead of the website.'

A BOX OF LETTUCE? THAT'LL BE £50 A box of 12 iceberg lettuces was on sale online yesterday for £50. A seller called Dave wrote on Gumtree: 'There are a national shortage of these beauties so the price is a little higher due to supply and demand.' But some social media users saw the funny side of the crisis. Karen Williams wrote: 'Get a grip and romaine calm, cos this could just be the tip of the iceberg.' Marcus Chown said: 'An inevitable consequence of global warming is no icebergs.' Another user wrote: 'Maybe there wouldn't be a shortage of iceberg lettuce in the UK if we'd voted ROMAINE…' Advertisement

Products listed as out of stock on the Morrisons website included bags of iceberg lettuce, wild rocket, and a large Mediterranean salad bowl.

Many products were out of stock on Ocado's website, which sells many Waitrose items. A spokesman said: 'We are not yet limiting quantities customers can buy but this is under review.' He said shoppers 'may need to be flexible about the brands or varieties they buy'.

Online yesterday, Sainsbury's had no iceberg lettuces or aubergines, Waitrose had no iceberg lettuces and Asda had no courgettes or aubergines.

Sainsbury's said: 'We take products off our website when we have limited stock to avoid customer disappointment.'

Waitrose said it takes products off the website if availability at the customer's nearest store is running low.

Spanish exporter federation Fepex has warned European vegetables will be in short supply until at least early April.

Bad weather has cut harvests by an estimated 60 per cent, with production wiped out in the Mediterranean. In a normal year, Spain ships more than 100,000 tonnes a month of lettuce, tomatoes, cucumbers and peppers.

Mitchell Redmond, who runs a fruit and veg stall in Essex, said wholesalers were charging £1.50 for an iceberg lettuce – at least double the normal price.

Ali Capper of the UK's National Farmers' Union said: 'For a reasonable price, there is plenty of home-grown fruit and veg for everyone.'

Sandwich seller's hunt for salad

Rhys Harris, who runs a sandwich shop in Cardiff, has struggled to buy ingredients

Fresh produce aisles in supermarkets around the country were blighted by empty boxes and notices apologising for low stocks and rationing yesterday.

Courgettes and all varieties of lettuce had sold out at a Sainsbury's in Streatham, south London. Just one aubergine sat on a shelf.

Customer Jean Byrne said: 'I felt angry … It's not impossible to go further afield to places like Africa if you can't grow the crops in Europe.'

Rhys Harris, who runs a sandwich shop in Cardiff, has struggled to buy ingredients. After his wholesaler's prices rocketed, he turned to supermarkets to fill the gaps, but was shocked to find shelves almost empty of vegetables at his local Asda.

The 40-year-old said: 'Nowhere has any stock. In the last two-and-a-half weeks it's the worst I have seen it by a long way. When I should be at home relaxing I am out looking for salad.'

The Tesco in Goole, East Yorkshire, was selling imported romaine lettuces from the US. Customer Alfred Smithson, 88, said: 'It's crisis point … If we ate more of our own produce instead of shipping it in from abroad we wouldn't have this problem.' Courgette displays were empty at Morrisons in Chorlton, Manchester, and lettuce rationing was being enforced at a nearby Tesco.

At a Sainsbury's superstore in Sale, customer Ewart Dowall, 72, said: 'It's odd when you go in to buy something you expect to be there and there is a gap on the shelf.' A Waitrose in the centre of Birmingham had sold out of iceberg lettuce. Melissa Nesbitt, who was using a Tesco Express in the city, said: 'I buy broccoli all the time as well as iceberg lettuce and it's really gone up in price. Compared to last week, I'm paying 10p more.'
