The Chair of the Oireachtas Agriculture Committee, Fine Gael TD Andrew Doyle, has said the committee will make a decision on Tuesday about whether to call the ABP Food Group before it for questioning.

The beef-processing firm, which owns the Silvercrest plant in Co Monaghan, is at the centre of the horse meat controversy.

It has lost contracts with a number of supermarkets after frozen burgers made at the plant were found to contain horse DNA.

Mr Doyle said a number of committee members want to question executives from ABP.

Minister for Agriculture Simon Coveney and officials from the Food Safety Authority are due to appear before the committee on Tuesday.

In a statement to RTÉ News, a spokesman for ABP said "while the company has not yet been contacted by the committee, it would carefully consider any formal request".
