LOS ANGELES — Burger King Corp. promised Wednesday to switch to only cage-free eggs and pork — a day after the re-emergence of mad-cow disease focused national scrutiny even more on Americans’ food sources.
The fast food giant, one of the largest in the world, said it would phase out cages for its chickens and gestation crates for breeding pigs by 2017 — making its pledge among the most sweeping of many such vows made recently by competitors such as McDonald’s and Wendy’s.
Burger King said its decision, which also includes provisions to only buy pork from suppliers who also plan to phase out gestation crates, was backed by the Humane Society of the United States.
