Mississippi has become the first state to ban the sale of lab-grown dairy products after legislators passed House Bill 1153 last week.
The law prohibits the manufacture, sale or offer for sale of cell-cultured dairy products in the state. The bill also expands and tightens the state’s rules on how “meat” and related products can be labeled and sold, and prevents “misbranding.” It will update multiple sections of state law to clarify definitions for meat, manufactured-protein, cultivated-protein, insect-protein and plant-protein products.
The bill defines cultivated dairy products as those “intended to replicate or to substitute for milk” and “derived from animal cells cultured outside of a live animal.”
The law will come into effect on July 1, and businesses found violating it could have their licenses revoked or suspended, and be fined up to $500 a day, with a maximum penalty of $10,000. It grants updated authority to state inspectors to ensure compliance and prevent “fake milk” from reaching shelves.
In 2026, the Mississippi legislature passed HB 1006, which banned lab-grown meat, effective July 1, 2025.
