All sausage and bacon in UK McDonald's McMuffins and the bacon in its premium salads and promotional burgers will now be sourced from Freedom Food approved farms, making it the UK's second largest buyer of pork from the scheme.

Warren Anderson, vice president, supply chain at McDonald's UK said: "Not only will our move to Freedom Food pork make it easier for people to make affordable, ethical choices on the high street, we hope that more of Britain's pig producers will have the confidence to invest in the future and adopt the RSPCA's higher-welfare standards on their farms."

The chief executive of the RSPCA's Freedom Food Scheme, added: "The Freedom Food market has been growing for a number of years, but having one of the UK's biggest restaurant chains serving only Freedom Food pork on its menu marks a major milestone for animal welfare."

Farming minister, David Heath welcomed the move saying: "It's essential that consumers have confidence with the way their food has been produced and sourced."
