Following a section in which a FIS is defined, an overview of the food industry and its research activities are presented to provide context for the current research and the discussion that follows. The methodology adopted for this research is then outlined with identification and discussion of the key actors in the FIS the focus of the next section. The main findings of the research are then presented, followed by conclusions and an outline of future research to be conducted on the Irish FIS.
