Minnesota’s Clean Indoor Air Act
turns 50
The law, enacted in 1975, has protected Minnesotans from the harmful effects of secondhand smoke.
Fifty years ago, Minnesota became the first state to adopt landmark legislation restricting smoking in indoor public places and workspaces. That legislation, the Minnesota Clean Indoor Air Act (MCIAA), protects workers and the public from the harmful effects of breathing secondhand smoke. It also has helped put smoking out of sight and out of mind – preventing young people from starting and encouraging people who smoke to quit. More information can be found on the News Release.

Keep food safe this summer
Bacteria flourish in the heat and humidity of the summertime. Make sure your summer gatherings don't go rotten by following some rules when preparing and cooking food. Wash your hands often and pack cleaning supplies for hands and surfaces, separate your foods (especially your meats) from each other and ready-to-eat foods, wash your fruits and vegetables, and always cook meats to their proper temperatures (160°F for hamburger, 165°F for chicken and turkey) to kill harmful bacteria. Learn more at Food Safety.

Test to be sure all’s well with your water well
More than 4 million Minnesotans rely on groundwater for their drinking water, and 1.1 million of them get that groundwater from a private well.
Wells can be a source of high-quality drinking water, but they require regular maintenance. If groundwater becomes contaminated, it can affect the health of those who drink it. More information can be found at Water Quality and Testing.
The Minnesota Department of Health and Tap-In Collaborative are offering free water test kits for private well households in eight southeast Minnesota counties in response to requests from the U.S. Environmental Protection Agency. The eight counties eligible for these test kits are: Dodge, Fillmore, Goodhue, Houston, Mower, Olmsted, Wabasha, or Winona counties. Test kits will include analysis for five common contaminants in well water including: coliform bacteria, nitrate, arsenic, lead, and manganese. Funding for the test kits is provided by the Clean Water Fund. More information can be found at Response to Nitrate in Southeast Minnesota.
