Horsemeat scandal: Government to hold food summit
12 February 2013 Last updated at 14:03 GMT
Environment Secretary Owen Paterson is due to meet food industry representatives for the second time in a week to discuss the horsemeat crisis.
Mr Paterson told the Commons on Monday that it appeared "criminal activity" had been at the heart of the scandal.
MPs will discuss the issue after Labour called a debate on Tuesday afternoon.
It comes after some Tesco Everyday Value spaghetti bolognese, withdrawn from sale last week, was found to contain 60% horsemeat.
