Martin McAdam of McAdam Food Products Ltd is suing ABP, a former arm of the Goodman Group, for defamation over a press release the company issued at the height of the controversy.
The release stated that horse DNA originating in Poland was present in some of the meat it had purchased from McAdam Foods.
The High Court heard Martin McAdam and his company claim that that this widely reported statement brought his business to its knees, by wrongly implying McAdams was the primary cause of the horsemeat scandal in Ireland.
ABP denies defamation and is awaiting a ruling today as to whether the court will direct McAdams' side to put up €640,000 as a security to meet the cost of defending the action.
