Last week Burger King pledged to only use cage-free eggs and crate-free pork by 2017, making it the first major fast food chain to do so. From Associated Press:
In a boost to animal welfare activists looking to get livestock out of cramped cages, Burger King will be the first major U.S. fast-food chain to give all of its chickens and pigs some room to roam.
On Wednesday, the world's second-biggest burger chain pledged that all of its eggs and pork will come from cage-free chickens and pigs by 2017, hoping to satisfy rising consumer demand for humanely produced fare and increase its sales in the process.
Other companies have made similar but less broad announcements this year, part of an industrywide shift to consider animal welfare when buying food supplies.
