A possible post-Brexit ban on the importation of potatoes from the UK could result in problems for chip sho owners.
From 1 January, UK table potatoes and seed potatoes could fall foul of EU food safety rules. When the UK becomes a third country it will be outside the legal framework of the European Union's food safety rules.
Many chip shops, use British potatoes for chips. One of the country's longest established chip shops is now warning that the ban could not only change the taste and type of chips Irish consumers enjoy, but could lead to shortages and changes in portion sizes.
Leo Burdock has said that they use British potatoes because of their unique quality which makes them suitable for frying.
Derek Duggan from Burdock says: "They have a better balance, chemically their composition, the dry matter and the sugars are more suited for the frying of chips, so that have that crispness and that flavour.
"Teagasc is working on developing a better home grown alternative, but they are not there yet."
