SUPERMARKET giant Tesco has apologised after burgers that were withdrawn after the horse meat scandal were found on the shelves at an Oxford store.

The company’s ‘free from’ frozen beef quarter pounders - which had been withdrawn as a precaution - were being sold at Tesco in Cowley.

A Tesco spokesperson said: “Whilst this product was not implicated in the Food Safety Authority of Ireland investigation, and was withdrawn as a precaution, we are urgently investigating how this product came to be on a shelf in store.”

She added: “We sincerely apologise for this, and we have spoken to the store to ensure that this does not happen again.”
