A bill to name cheese as Wisconsin’s official dairy product is tentatively scheduled for a vote in the state Assembly next Tuesday. Livia Doyle’s fourth grade class at Mineral Point Elementary School proposed the new state symbol — and committees in both the Assembly and Senate have endorsed their own bills. The dairy cow was named Wisconsin’s official domestic animal in 1971, and milk became the state’s official beverage in ’87. But cheese has never been honored with its own symbol, even though the Badger State has long been the national leader in cheese production.
