No horse DNA found in latest tests on Liffey Meats burgersMonday 21 January 2013 22.02
Laboratory test results published tonight show no presence of equine DNA in a range of beef burgers manufactured by Liffey Meats between 10 and 16 January.
The Department of Agriculture said the news supported claims by the company that it has addressed any concerns that arose from the findings of the Food Safety Authority's survey in December.
Those tests found trace levels of equine DNA in three of their burger products.
Investigations are continuing in relation to identifying the source of the equine DNA in the Silvercrest processing facility in Co Monaghan.
Test results are expected to be released mid-week.
Samples taken by the Department of Agriculture last week were found to have traces of horse DNA and were sent to a German laboratory.
A department spokeswoman said the focus of the analysis was still on imported ingredients that were used in the production of the burgers.
A Silvercrest spokesman said the company was carrying out its own internal investigation and would not be commenting ahead of the test results.
Last week it was announced that horse and pig DNA had been found in frozen beef burgers on sale in Tesco, Dunnes Stores, Lidl, Aldi and Iceland.
The burgers in question were produced at two Irish processing plants; Silvercrest Foods and Liffey Meats, and one plant in the UK, Dalepak Hambleton.
Officials said there was no risk to health from the burgers, but the source of the problematic ingredients is being investigated.
One burger from Silvercrest was found to contain 29% horse meat.
However, most of the finds from the Irish factories were relatively small.
