McDonald's said it will get its pork suppliers to phase out the use of immobilizing cages for pregnant pigs, a move that was applauded by the Humane Society of the United States, but not the pork industry.
"McDonald's believes gestation stalls are not a sustainable production system for the future," said the fast food chain in a press release. "There are alternatives that we think are better for the welfare of sows."
Animal activists oppose the use of gestation stalls, which are cages that keep individual sows in close confines while they're pregnant.
"Confining pigs in gestation crates is arguably the cruelest practice in factory farming," said Josh Balk, spokesman for the Humane Society of the U.S. "These are iron maidens that are barely larger than the pigs' own bodies."
