Sainsbury's boss: Long way to go on horsemeat problems
The chief executive of Sainsbury's has said retailers are not "out of the woods" yet over the horsemeat scandal.
Justin King told the BBC there was still a long way to go before stores could be certain of how similar problems could be prevented in the future.
His remarks came as the Food Standards Agency announced it had removed computers, documents and samples from three manufacturers in London and Hull.
