The food safety watchdog has pledged a relentless investigation into allegations of horse meat being passed off as beef in the UK after two British plants were raided and shut down as part of the inquiry into the scandal.
Andrew Rhodes, Food Standards Agency (FSA) director of operations, said they would keep pursuing an investigation into a meat processing plant in west Wales and into a slaughterhouse in West Yorkshire until there is "nothing left to find" after discovering evidence of apparent "blatant misleading of consumers".
Yesterday, meat processing plant Farmbox Meats at Llandre in Aberystwyth, west Wales, had records seized and were temporarily shut down pending the outcome of investigations into claims they supplied and used horse carcasses in burgers and kebabs.
The Welsh Government's Deputy Minister for Agriculture, Alun Davies, said: "Integrity and trust are essential in the food chain.
"I would be appalled if these allegations are proven.
"The Welsh Government is working closely with the Department for the Environment, Food and Rural Affairs (Defra) and the FSA to ensure this matter is dealt with swiftly and decisively."
