The director of one of the firms raided as part of an investigation into alleged horsemeat mislabelling said the Food Standards Agency (FSA) was "picking on" him.
Dafydd Raw-Rees, of Farmbox Meats, said it was business as usual at his company.
But the FSA claimed horse carcasses sent to Farmbox Meats Ltd, of Llandre near Aberystwyth, had been used in beef products.
