History: 1993 a. 492.
A warrantless inspection of a dairy farm under authority of ss. 93.08, 93.15 (2), and 97.12 (1) and related administrative rules made without prior notice and without the owner being present was not unconstitutional. Because the administrative rules govern operations, equipment, and processes not typically conducted in residential areas, the rules and statutes sufficiently preclude making warrantless searches of residences.
