Two years in, Prop 12 pork still costs 20 percent more. The farm bill would end it.

When California's Proposition 12 took full effect in 2024, the argument from the state was that the pork price increase would be temporary as the supply chain adjusted. Researchers at North Dakota State University's Agricultural Risk Policy Center have now looked at two years of data, and it did not.

What the study found

• Prices for pork products covered by Prop 12, whole cuts sold in California, have averaged about 20 percent higher than they would have without the law, and the gap has persisted rather than closed.
• California consumers have paid roughly $350 million more for pork, and pork consumption in the state has declined meaningfully.
• The cost to a producer of retrofitting or rebuilding sow housing to meet the California standard runs about $3,500 to $4,500 per sow.

That last number is why most producers never converted. For a 2,500-sow farm, compliance is a $9 million to $11 million decision to serve roughly 13 percent of the U.S. pork market, with no guarantee the premium covers the debt.

Where the fix stands

The House-passed Farm, Food, and National Security Act of 2026 includes language, backed by the National Pork Producers Council, that prevents one state from setting production standards for livestock raised in another. NPPC's framing: family farms should not have their barns designed by a state they do not sell in.

The Senate Agriculture Committee's version is where this gets decided. The committee's August markup stalled on SNAP, not on Prop 12, but the provision is contentious enough that it could become a bargaining chip when the committee returns in September. The current farm bill extension expires September 30.

The hog market itself

Prop 12 is a cost problem layered on a market that is otherwise fine but not great. USDA's outlook has 2026 hog prices down about 2.6 percent from 2025, with pork production at 28.2 billion pounds, up 2.3 percent. Cutout values held up through the summer grilling season on strong bellies and hams, and export demand, especially to Mexico, remains the pillar.

The wildcard, same as for cattle, is corn. Hog margins in 2025 were built on cheap feed. The August rally put roughly $8 to $10 per head back on the cost side, and if Thursday's WASDE confirms a smaller crop, the fourth quarter tightens quickly.
