No horse or pork DNA has been found in tests carried out on beef products taken from a North Yorkshire firm.
The Food Standards Agency (FSA) said it had carried out the tests on samples taken from Dalepak Ltd.
It emerged in January that some frozen beefburgers supplied by Dalepak and two Irish firms, on sale in the UK and the Irish Republic, contained horsemeat.
The FSA said investigations into the origin of horse and pork DNA detected in those products was continuing.
Burgers on sale at several supermarkets were taken off the shelves after tests in Ireland found horsemeat accounted for nearly 30% of the meat content in one sample
