The Food Safety Authority of Ireland is renewing its appeal to people to boil all imported frozen berries before eating them.
The warning was originally provided last year when a food poisoning outbreak of the Hepatitis A virus - linked to imported frozen berries - was first identified in Ireland.
To date 1,440 cases have been reported in twelve European countries - the majority in Italy.
25 cases were reported in Ireland - 21 of which were confirmed.
The FSAI said people should boil the berries for a least one minute before they consume them.
