All sausage and bacon served in McDonald's meals will now be sourced from farms that meet strict animal welfare criteria set down by the RSPCA, the restaurant has announced.
From the end of April, meat in McMuffins to premium salads will only use 100% Freedom Food pork, currently delivered by less than a third of British pig farmers.
The Freedom Food scheme goes beyond industry standards and legislation with farmers required to provide bright, airy environments, bedded pens and plenty of space for pigs to move around in.
McDonald's said it hoped its support for the scheme would encourage more pork producers to adopt the criteria on their farms, while allowing customers to make "affordable, ethical choices on the high street".
Test results show pork was present in a sample of halal chicken sausages which may have been supplied to 19 schools and nurseries. A further sample of non-halal lean mince beef shows that pork and lamb was present, potentially affecting 17 schools and nurseries
