The region where food shortages could fast become a real issue is Northern Ireland, where images of empty supermarket shelves have circulated on social media.
Due to the unique position of Northern Ireland, it has split with the rest of the United Kingdom and remained inside the EU single market, making it a lot harder to import food from Great Britain.
Simon Coveney, Ireland's foreign affairs minister, said that images showing empty shelves in Northern Irish supermarkets were "clearly a Brexit issue" and "part of the reality" of the United Kingdom leaving the European Union.
