Cal. Health & Saf. Code § 109971
"Medical food" means any product that meets the definition of medical food in the Federal Food, Drug, and Cosmetic Act (21 U.S.C. Sec. 360ee(b)(3)). The department shall review all changes to the federal definition of "medical food" before those changes are incorporated by reference pursuant to this section. Within six months after the effective date of any changes to the federal definition, the department shall complete its review of the changes, and submit a report to the Senate Health and Human Services Committee and the Assembly Health Committee that describes the changes and makes a recommendation as to whether it is appropriate to incorporate the changes by reference pursuant to this section. Any change to the federal definition shall take effect pursuant to this section one year after the effective date of the federal change, unless a law that specifically prohibits the change from taking effect is enacted and becomes effective.
