What this bill does

Plain-language analysis by the nonpartisan Legislative Reference Bureau

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.
