Assembly Bill 554 aims to regulate the sale, service, and labeling of food products containing lab-grown meat, defined as cultured animal cells or tissue derived from such cells. The bill mandates that any packaged food product containing lab-grown meat must be labeled with the phrase "lab-grown meat" in a prominent manner, alongside a complete list of ingredients. Additionally, it prohibits the sale of lab-grown meat in public eating places unless specifically ordered by the customer and restricts its service to students, patients, or inmates in state institutions, except under certain health-related circumstances.

Violations of these regulations can result in criminal penalties, with fines ranging from $100 to $1,000 and potential imprisonment for up to one year, depending on the number of offenses. The bill also establishes specific labeling requirements, including the size and contrast of the text used for the "lab-grown meat" label. The act is set to take effect on January 1, 2027.
