Bill Summary
Under this bill, no person may sell or offer for sale a food product, including a drink, that contains a liquid that replicates milk but is not harvested from a mammal (lab-grown milk) unless the food product is labeled with the phrase “lab- grown milk.” The bill also imposes certain labeling requirements for persons selling lab-grown milk packaged food products, including the requirements that the packaged food product’s label list all ingredients and bear the phrase “lab-grown milk.” Finally, the bill prohibits the sale or service of lab-grown milk food products in a public eating place or at certain state institutions, with certain exceptions. A person that violates the bill’s prohibition may be subject to a criminal penalty of between $100 and $1,000 per violation or imprisoned for up to one year, or both. For further information see the state fiscal estimate, which will be printed as an appendix to this bill. LRB-6150/1 ARG:skw&wlj 2025 - 2026 Legislature SENATE BILL 1009
AI Summary
This bill, effective January 1, 2027, establishes regulations for the sale, service, and labeling of food products containing "lab-grown milk," which is defined as a liquid that mimics milk but is not derived from a mammal. It mandates that any packaged food product containing lab-grown milk must be clearly labeled with the phrase "lab-grown milk" in a size and color that contrasts with other text, and must also list all ingredients. If a product contains multiple individually packaged components, each component with lab-grown milk must also bear this specific labeling. Furthermore, the bill prohibits the sale or service of food products containing lab-grown milk as a milk substitute in public eating places unless specifically ordered by the customer, and restricts its service in state institutions like schools, hospitals, or correctional facilities, with limited exceptions for medical necessity. Violators face penalties ranging from fines of $100 to $1,000 and/or imprisonment of up to one year, with penalties increasing for subsequent offenses.
