When part of the European Union, countries are free to import and export produce without being heavily taxed by producing/consuming countries. In light of our controversial exit from the EU, negotiations over an exit deal seem to not be going quite as planned and we may be looking at some very steep tariff barriers; a lot of the food we produce and consume crosses multiple borders before it reaches the supermarket shelves. Up to 97% of British food and drink exports will be susceptible to these taxes and imports will be equally taxed, meaning not only will our food sector be making significantly less money but we will also likely be paying more for our food. With the value of the pound lower than it has been in a long time, our economy is looking more unstable than ever.
Without access to the EU farm subsidies, the export connections around the rest of the world, and the significantly cheaper imports available to EU members, the food sector has a lot of potential problems. Farming is already an extremely tasking occupation with little turnover and so unless these problems can be overcome I would not be surprised to see the food produced in the UK diminished even further. This would leave us more dependent than ever on imported food with increasing tariffs.
