The FSA is spending up to £500 to test food samples for horse and pig.
Food minister David Heath said the FSA was paying about £300 to test each sample, of which £250 was accounted for by lab costs, and £50 went to the local authority that had collected the sample. On top of that, the FSA was paying an extra £250 to get the DNA results back more quickly, Heath said in a written statement to the House of Commons.
The FSA said it could not say how many samples had required the extra £250 fee but stressed it was not all of them. It is testing 514 samples for horse and pig DNA as part of its official testing programme, and said it did not yet have a figure on total costs.
