Listen "Understanding AB 411 and What It Means for California Dairy Farms"
Episode Synopsis
In this episode, the team breaks down AB 411, also known as the C.A.T.T.L.E. Act—the new law allowing California dairy producers to compost animal mortalities on-farm once safety standards are in place.Governor Newsom’s recent signature on the bill marks a major step toward more flexible, sustainable mortality management. But what exactly does the law do? When can dairies start composting? And what should producers be doing in the meantime?Our guests walk through the CDQAP Advisory Q&A, answering the most common questions from producers and explaining what to expect next from the regulatory process.Key Takeaways AB 411 takes effect January 1, 2026. Until then, composting mortalities remains prohibited.CDFA will develop Best Management Practices (BMPs) before composting begins. These will cover water protection, odor and fly control, and pile management.The law applies statewide—to all livestock facilities, regardless of size or location.Composting materials and finished compost must stay on the same agricultural site to protect biosecurity and traceability.Don’t cancel your rendering contracts yet. Current water board and Dairy General Order requirements still apply.WUD, CDQAP, and CDRF will provide guidance, training, and updates as BMPs are developed.Why It MattersWith rendering options shrinking and transportation costs rising, AB 411 gives producers an additional, environmentally responsible option for managing routine animal losses—something long supported by Western United Dairies and the broader agricultural community.
