BEEF burgers labelled "Irish" are not necessarily made entirely of Irish beef.
Complex labelling rules mean they can be labelled Irish even if some of the meat is imported.
The "substantial transformation" rule means the raw material can originate from elsewhere.
Some burger brands specify their products contain "100pc Irish beef", which means it has to be reared and slaughtered in Ireland.
Bord Bia's "Quality Assured" scheme also allows firms to use a logo that is supposed to guarantee 100pc Irish meat produced to high standards.
