Updated Evidence on Proposition 12 Impacts on Pork Prices, Wholesale Segmentation, and Consumption

➩ Retail Pork Price Premiums Remain Elevated Two Years After Full Enforcement. From January 2024 to January 2026, the pooled retail price gap between compliant-state markets and the conventional benchmark market averaged 85.4 cents per pound, up from a pre-enforcement average of 14.2 cents per pound. This implies an overall widening of 71.2 cents per pound, with state-specific estimates of 72.7 cents per pound in California and 62.8 cents per pound in Massachusetts.

➩ Proposition 12-Compliant Pork Remains a Small but Higher-Priced Share of Wholesale Markets. At the wholesale level, ACL-compliant pork accounted for an average of 5.3% of reported volume from January 2024 to January 2026, peaking at about 7.2%. Over the same period, the volume-weighted ACL price premium averaged 51.6 cents per pound, compared with 27.4 cents per pound before enforcement, implying a full compliance-attributable wholesale premium of 24.2 cents per pound.

➩ Retail Price Increases Are Nearly Three Times Larger Than the Wholesale Compliance Premium. The retail price gap widened by 71.2 cents per pound, while the wholesale compliance premium widened by 24.2 cents per pound relative to the same pre-enforcement baseline. This yields an amplification factor of 2.95 overall, with corresponding estimates of 3.01 for California and 2.60 for Massachusetts, indicating substantial amplification between the wholesale and retail levels.

➩ Higher Consumer Costs Coincide With Lower Pork Purchases and a Large Retail Burden. California’s share of U.S. pork purchases declined from 8.5% to 7.1% in the post-implementation period. Estimated additional consumer spending totals $403.1 million at retail in California and Massachusetts combined, compared with $184.7 million in wholesale compliance costs. Of the $403.1 million retail burden, 54.1% is attributable to retail amplification, 30.2% to the producer premium, and 15.7% to packer net margin, indicating that most of the burden arises after the packing plant and before the final retail sale.

➩ Retail Cost Estimates Likely Understate the Full Consumer Burden. Retail scanner data capture only grocery-channel sales. Comparing wholesale ACL volume with retail scanner ACL volume implies that about 199 million pounds, or 26% of total reported ACL production, clears through non-retail channels, such as foodservice, further processing, and institutional sales. Applying the wholesale compliance premium to this volume implies an additional $48.1 million in compliance costs not captured in the retail estimate, suggesting that total consumer costs across all channels exceed the reported $403.1 million retail burden.
