Union representatives are expected to meet management of the Kildare Chilling company later today amid fears for the future of 350 jobs at the plant.
A major fire on Friday is thought to have caused extensive damage to at least two of the three main production lines at the meat processing facility.
The company has been a significant employer for the people of Kildare town since the 1960s.
The full implications of the fire are expected to become clear during today's talks between unions and management.
