53 job losses have been confirmed at C&D Foods in Edgesworthtown, Co Longford.
The job cuts at the petfood plant had first been signaled in April and unions at the plant entered consultation meetings with management at that time.
'Unfortunately the consultation process failed to secure any of the 53 jobs and statutory notice was issued to the workers', a statement from SIPTU said today.
The plant has a workforce of about 200 after shedding 29 jobs earlier this year. In March 2008, Larry Goodman's owned Irish Food Processors said it was investing €30m in the plant.
