MIssissippi plans to become the first state to ban lab-cultured dairy products.
The proposed legislation would classify cell-cultured dairy separately from conventional milk products and make it illegal to manufacture, market or sell these products within the state.
Violators could face civil penalties of up to $500 per day, with total fines capped at $10,000 for the same offense.
It earlier banned cell-cultured meat product, joining Florida and Alabama to protect livestock farmers.
