Newry and Mourne Council's environmental health department said that DNA tests on samples of burgers made at Freeza Meats were found to be free from non-beef DNA.
A statement from the council said that twelve samples of Polish meat belonging to another company were being stored in freezers on the company's premises, but that they had been detained due to "queries" about traceability:
Two of these samples contained approximately 80% horse DNA. This meat had been detained for the last five months due to the condition of its wrapping and queries regarding its labelling and traceability.
