Frank Mallon is a member of Ireland's Rich List and the company based in Ballyjamesduff, Cavan, just opened a new meat processing factory last year.
But back in the 1990s, owner Frank Mallon was embroiled in controversy.
As a farmer, he was fined on charges relating to the possession of hormones and administering prohibited substances to cattle.
He was one of seven defendants brought before the courts in 1996 on 25 charges of using drugs in meat production.
All pleaded guilty and were fined a total of £104,000 by Judge John Brophy, who warned that had they chosen to plead not guilty and been convicted, he would have jailed them.
"No one knows at this stage what the effects of using these drugs in meat production will have on humans in 10-15 years' time," Judge Brophy commented.
Liffey Meats are one of Ireland's largest beef processors and have built up a significant supplier base from quality assured farms which they said guarantees complete traceability.
The company said that it has withdrawn from sale all products with non-beef DNA traces identified by the FSAI.
