Beefburger products made by a mid-Wales firm have been withdrawn after tests revealed the presence of horsemeat.
Three samples of beefburger products made by Builth Wells catering supplier The Burger Manufacturing Company tested positive for at least 1% horsemeat.
The test were requested by the Food Standards Agency and carried out by Powys County Council.
Further tests will now be carried out to establish how much horsemeat the products contain and to test for the presence of the veterinary medicine phenylbutazone.
The FSA said the company is contacting its customers to inform them of the results and to recall any affected products.
