A lack of border control at Port of Cork means consumers are paying more for their fruit and vegetables.
Over two thousand containers of fresh produce are being turned away each year from the port.
Containers are then being re-routed to ports such as Southampton or Antwerp, before heading for Dublin.
Speaking to RedFM news, Brian Dooley, from the Port of Cork company says extra transport costs for importers is causing the price hike:
"Approximately 15 to 20% of the units that are for Ireland cannot come off in Cork. So that's where ultimately there is an increased cost for the importer, predominantly for the fruit importer, and that will eventually, it will come and hit the pocket of the consumer.
