TL;DR
Millions of Americans voted to ban gestation crates for pigs in California and Massachusetts. Congress is now considering legislation, included in the Farm Bill, that could reverse these laws. The industry and animal advocates are at odds over the move, which could affect animal welfare and pork trade.
Congress is advancing legislation that aims to nullify California and Massachusetts laws banning the use of gestation crates for pigs, despite widespread public support for animal welfare reforms. The move could significantly impact efforts to improve conditions for millions of pigs raised in confinement, and is part of the ongoing political battle over animal rights and agricultural industry interests.
Most of America’s 6 million female breeding pigs are confined in gestation crates, which prevent them from turning around and cause significant stress and suffering, according to animal welfare experts. California and Massachusetts voters approved laws in 2018 and 2020 respectively, banning the use of these crates and the sale of pork from farms that use them. Despite legal challenges from the pork industry, courts have upheld these laws, including a 2023 Supreme Court decision affirming California’s law as constitutional.
However, the industry has lobbied Congress for over a decade to pass federal legislation that would invalidate these state laws. The latest effort, called the Save Our Bacon Act, was included in the House Farm Bill passed in April 2025. This legislation aims to preempt state laws by establishing a federal standard that allows the continued use of gestation crates, effectively reversing the recent state-level reforms.
Industry groups like Triumph Foods and the National Pork Producers Council argue that the laws violate the dormant commerce clause, which restricts states from enacting laws that unfairly burden interstate commerce. Conversely, animal advocates and many farmers who have transitioned to group housing say the legislation undermines efforts to improve animal welfare and reflects industry resistance to change.
Why It Matters
This development is significant because it could roll back popular and legally upheld animal welfare laws in California and Massachusetts, which have influenced other states and industry practices. If the federal legislation passes, it could lead to a resurgence of confinement practices that many consider inhumane, affecting millions of pigs and setting a precedent for federal interference in state-level animal protections. The move also highlights ongoing tensions between industry interests, animal rights advocates, and consumers demanding more humane farming practices.

Background
Since the early 2000s, several states have enacted laws to improve pig welfare by banning or restricting the use of gestation crates. California and Massachusetts were among the first to do so through ballot initiatives supported by public votes with large majorities. The pork industry has challenged these laws in courts, but courts have generally upheld them, including a 2023 Supreme Court ruling in favor of California.
Despite legal defeats, industry groups have continued efforts to pass federal legislation to preempt state laws, arguing that such laws disrupt interstate commerce and impose unfair burdens on producers. The current legislative push is part of the broader debate over animal welfare versus industry regulation, with the Farm Bill serving as the legislative vehicle.
“A vote for the farm bill is a vote to cage an animal that can’t walk or turn around.”

“Gestation crates are akin to forcing a human to live in an airline seat.”
