Health officials in Scotland are investigating an E. coil outbreak there.
One elderly woman has died and her husband is seriously ill.
Four other people are recovering at home as a result of the infection.
The outbreak has been linked to cold meats sold at two branches of a supermarket chain in Paisley in Scotland.
There are unconfirmed reports that a Scottish woman is being treated for the E. coil infection in a hospital in Ireland.
The Department of Health and Children in Ireland has not been formally notified of a patient being treated in hospital for an E. coil infection, however, a spokesperson said that a woman from Paisley in Scotland has been hospitalised while on holiday.
