Horsemeat: Powys council 'not complacent' over supplies
Seven Welsh councils say they were supplied with burgers made by a firm where horse DNA has been found.
The Burger Manufacturing Company (BMC), at Llanelwedd, Builth Wells has since withdrawn suspect products after three samples tested positive for horsemeat.
BMC said its meat came from Farmbox Meats in Ceredigion, which is already under police investigation.
Monmouthshire, Blaenau Gwent, Merthyr, Rhondda Cynon Taf, Caerphilly, Powys and Neath Port Talbot councils are affected.
David Jones, leader of Powys council, said he does not think the authority had been complacent.
