The Food Safety Authority of Ireland is again urging consumers to boil all imported frozen berries before eating.
It made the call after several more cases of Hepatitis A were linked to the berries in recent weeks.
"The first indications of this outbreak emerged when cases of hepatitis A were identified to have the same strain of the virus as that causing an outbreak in Italy, said Alan Reilly, Chief Executive.
"Since the outbreak was identified, a small number of new cases have been reported and it would be prudent for consumers to continue to boil these berries until further notice."
The fruit should be boiled at least one minute prior to consumption.
Irish berries grown here are not believed to be affected.
