Burger King and Wolfgang Puck made major announcements in their animal welfare standards last month. The Associated Press reports Burger King told People for the Ethical Treatment of Animals that it will purchase 10% of its pork from suppliers that don't use sow gestation crates, and will double that amount by the end of 2007. It also plans to procure 2% of its eggs from cage-free hens, doubling it by the end of 2007, and favor processors that use gas rather than electricity to stun birds.
Earlier, celebrity chef Wolfgang Puck announced his companies and dining venues will only use eggs from cage-free hens, and all-natural or organic crate-free pork and veal.
The announcements come on the heels of a January announcement by Smithfield Foods, the world's largest pork processor, to phase out crate confinement of pigs over the next decade.
