SB 1009 Wisconsin Senate · 2025-2026 Regular Session

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

SB 1009 requires clear labeling for food products containing lab-grown milk (defined as liquid replicating milk but not from mammals). It mandates that such products display "lab-grown milk" prominently on labels, include full ingredient lists, and use 20-point type for separate components containing it. The bill prohibits using lab-grown milk as a milk substitute in restaurants unless ordered by a customer, and bans its use in state institutions (like hospitals or prisons) except for specific health needs. Violations carry fines of $100-$500 for first offenses and $500-$1,000 for repeat offenses. The law takes effect January 1, 2027, directly affecting food manufacturers, restaurants, and retailers selling these products.
