It appears the bulk of Burger King's pork is currently being served at breakfast, but there are plans in the works for a pulled pork sandwich from the chain. (Photo by Mark H. Anbinder.)

As of today, Burger King is calling itself the “first U.S. national chain to pledge cage-free pork and eggs.”

Never heard of “cage-free pork”? Neither had I. In fact, I’m guessing that the PR executives at Burger King may have invented it. There are cage-free eggs, yes. That term refers to eggs from chickens that are raised outside of tiny battery cages (the industry standard), but are still in confinement.
