Relating to: the sale, service, and labeling of food products containing lab-grown milk and providing a penalty. (FE)

AB 1024 requires food products containing lab-grown milk (defined as milk replicated without mammal harvesting) to be prominently labeled with the phrase "lab-grown milk" in large, contrasting text on packaging. It mandates full ingredient lists and specific labeling for multi-component products. The bill prohibits using lab-grown milk as a milk substitute in restaurants without customer order and restricts its use in state institutions like schools or hospitals without medical authorization. Violations carry fines of $100-$500 for first offenses and up to $1,000 for repeat violations. The law takes effect January 1, 2027.
