The very real possibility of a no-deal Brexit has sparked concerns about rising food prices and supply shortages in the UK. Forty percent of the fresh produce, including fruit and vegetables, consumed in the country comes from the European Union. These products could be subject to delays and tariffs if the UK leaves the bloc without a deal. CGTN's Juliet Mann has the story on how savvy shoppers have been preparing.

"This is a serious kit with something to sow every month of the year and we've sold over 500 in just a few weeks."

This Brexit vegetable survival kit has become an unexpected hit for one London-based seed seller who says demand at his store has increased.

PAOLO ARRIGO SEED MERCHANT "As a whole the EU supplies us with lots of fresh vegetables and you can't stockpile fresh vegetables like you can't stockpile insulin and some other medicines. So that is why people are wanting to stockpile and grow their own to have uninterrupted supplies for their families."

The UK only produces half of what it eats and much of what it imports comes from the European Union.

After Brexit, the flow of goods could be hampered by border checks, delays in transit and additional tariffs.

JULIET MANN LONDON "There are plenty of British made staples such as flour, oats, salt & vinegar. But those everyday foods we've got a taste for that come from the EU might be harder to find and more expensive."

Items like olive oil, tomato paste, tinned fish, sausages, rice, sparkling wine, specialty peppers, regional cheese, salami, pasta. Helena is a member of a growing online community sharing stockpiling tips. This is pantry is her Brexit backup.

HELENA BREXIT STOCKPILER "I've been preparing for about 3 months' worth of human food, and I've prepped for about a year's worth of dog food. We're the world's 6th largest economy; we shouldn't have to do this in the first place!"

The government department for food is working with manufacturers and producers to limit potential disruption to the food chain. Stockpiling? They say that's up to you.

"We've got plenty of food here, we grow food here, we'll be fine."

"It is ridiculous, everyone stockpiles so there is nothing in the shops."

"I would like to buy more food and stock my cupboards."

"I'm not going to panic."

But a recent grocery survey says one in ten shoppers is storing food for Brexit. They see it not as an unnecessary extravagance but as a sensible insurance plan that could reap rewards come Brexit day. Juliet Mann, CGTN, London.
