Relating to: designating the bacterium Lactococcus lactis as the Wisconsin state microbe.

SB 402 designates *Lactococcus lactis* (a bacterium used in dairy fermentation) as Wisconsin’s official state microbe. The bill amends Wisconsin statutes to add this designation to the list of state symbols included in the Wisconsin Blue Book, alongside items like the state song, bird, and tree. It does not create new laws or affect any policies, programs, or people - only formally recognizes this microbe as a symbolic representation of Wisconsin. This is a ceremonial measure, consistent with similar bills naming state symbols.
