The Independent reports that Tesco, Asda, Sainsbury's, Morrisons, Waitrose, Marks & Spencer and the Co-op plan to change labelling to clearly show the origin of foreign pork, bacon and ham in processed products such as pies, pasties and sandwiches. The change, to be announced by the Environment Secretary Hilary Benn, follows complaints that shoppers wanting to support domestic farmers and higher animal welfare are being misled about the origin and provenance of meat. Retailers will be banned from using national terms and symbols on products unless the meat comes from within the UK.
