On March 6, 2000, the city of Duluth adopted the nation’s first-ever ban on the sale of mercury fever and basal (used by women)thermometers. The purpose of this ordinance is to help eliminate mercury from the waste stream.
An earlier Minnesota law (M.S. Section 116.92, subd. 7) prohibits medical facilities from routinely distributing mercury thermometers. Another state law (M.S. Section 115A.932) prohibits depositing them in solid waste.
