A new code of practice, drawn up between industry and government is set to bring clarity to country-of-origin labels for pork.

The code has been drafted by the Pig Meat Supply Chain Task Force, set up earlier this year by Defra to address abuses such as unclear country-of-origin labelling within the pigmeat supply chain.

The code will require signatories to be more precise as to the exact source of the pork they sell. For example, labelling meat as British will mean that the animal it came from was born, reared and slaughtered in Britain. "This is a very significant step forward by all elements of the pig meat supply chain to provide consumers with even greater confidence in what they purchase," said chief executive of Bpex, Mick Sloyan.

Tesco, Asda, Sainsbury's and Morrisons are all members of the Task Force and are expected to sign up to the code.
