The Chief Veterinary Officer of Ireland has been notified and investigations into the case, including the destination of and documentation relating to this consignment, are continuing.
The meat tested negative for BSE, but it is illegal under UK law to sell for human consumption meat from animals aged over 30 months.
The discovery that the cattle were aged over 30 months was made on Friday 4 January as the consignment was being unloaded at ADM Ltd, Eastbourne. The beef came from O'Farrell Meats in County Cork, Ireland.
