What Is at Stake
A federal farm bill advancing through Congress could nullify animal welfare standards adopted by California and more than a dozen other states, touching everything from hog confinement practices to egg production requirements. California — whose economy ranks fourth-largest in the world — faces the broadest exposure given the reach of its existing livestock rules into out-of-state supply chains.
How the Bill Reached This Point
Congress renews the farm bill roughly every five years. The package governs food assistance programs, crop subsidies, and a wide range of agricultural policy. Late in April, the House passed the latest version by a vote of 224 to 200.
Embedded in that legislation is the Save Our Bacon Act, introduced by U.S. Rep. Ashley Hinson of Iowa. The provision would strip individual states of authority to regulate how livestock are raised in other states — a direct challenge to laws like California’s Proposition 12.
What California’s Law Requires
Proposition 12 was approved by California voters in 2018, with 62 percent in favor. The measure requires farms to give animals adequate space and freedom of movement, prohibits gestation crates in hog operations, and sets minimum floor space standards. It also bars retailers from selling pork or other meats that originate from farms failing to meet those standards, wherever those farms are located.
The House-passed farm bill targets the hog-confinement requirements under Proposition 12 but leaves its protections for egg-laying hens intact. Battery cage restrictions affecting hens would not be overridden under the current draft language.
By the Numbers
- 224–200: The House margin approving the farm bill in late April.
- 62%: Share of California voters who backed Proposition 12 in 2018.
- 600+: State agricultural regulations that could be invalidated by the Save Our Bacon Act, according to an analysis by the Harvard Law School Animal Law and Policy Clinic.
- 15+: States that have independently enacted bans on battery cages, gestation crates, or veal crates.
- ~5 years: The typical interval between farm bill reauthorizations.
Arguments on Both Sides
Supporters of the preemption provision argue that a single state’s ballot measure should not effectively set production standards for farmers nationwide. Hinson has defended the measure in public statements, saying: “This legislation will stop out-of-touch activists — who don’t know the first thing about farming — from dictating how Iowa farmers do their job.”
Texas Agriculture Commissioner Sid Miller has pointed to Proposition 12 as a factor pushing up retail prices for pork and eggs, framing the debate in terms of consumer costs rather than regulatory philosophy alone.
Opponents warn that unwinding the law now would damage supply chains that producers have already reorganized to comply with California’s standards. California Assemblywoman Esmeralda Soria argued that removing the measure at this stage “would create long term uncertainty and disruption to California meat and egg production.”
Wider Implications
The preemption question extends well beyond California. Because at least 15 states have enacted their own restrictions on specific confinement practices, a federal override would reach regulatory frameworks that multiple state legislatures built independently. The Harvard Law School clinic’s finding — that more than 600 state agricultural rules could be affected — has drawn attention from lawmakers whose states have no connection to Proposition 12 but whose own regulations could face the same legal exposure.
California’s law is particularly contentious because it applies to products sold within the state regardless of where they are produced, effectively requiring out-of-state farmers to meet California’s standards if they want access to that market. Farm groups in several states have challenged that aspect of the law.
What Comes Next
The legislation moves to the Senate, where the animal welfare preemption language is expected to draw scrutiny. Senate negotiators will need to reconcile their version with the House-passed text before a final bill can go to the president. Whether the Save Our Bacon Act’s core provisions survive intact, are narrowed in scope, or are removed during that process remains an open question — one that producers, state governments, and agricultural interests across the country are tracking closely.
