Overview
- AB 1830 requires mass-produced packaged masa harina, tortillas and other corn masa products sold in California stores to be fortified with folic acid.
- The statute sets 0.7 milligrams of folic acid per pound for corn masa flour and includes a separate provision for wet masa products.
- Small, mom-and-pop tortilla makers are exempt, while large manufacturers must comply beginning January 1, 2026.
- The bill passed unanimously in the Legislature and was signed by Gov. Gavin Newsom, and companies such as Mission Foods already fortify and support the mandate.
- Officials cite lower pre-pregnancy folic acid use among Latinas and higher neural tube defect rates as the rationale, even as some critics warn of possible taste changes.
