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.
Toxic Free Kids Program
From lead in toys to mercury in skin-lightening products to formaldehyde in laundry detergent, many consumer products sold in Minnesota contain chemicals that can harm people’s health. The 2025 Minnesota Chemicals of High Concern Report (PDF) contains an updated list of these chemicals along with examples of how the Toxic Free Kids (TFK) Program at the Minnesota Department of Health (MDH) is working to protect people, especially children, from negative health effects. For more information, visit the Toxic Free Kids Program webpage.
TFK Program updates Chemicals of High Concern list. Expanded outreach and education work focuses on risk of exposure through consumer products. Learn more on 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.

Natural Disasters and Severe Weather
Disasters can happen anywhere, at any time, often with little or no warning.
Wildfires are becoming larger and more frequent in the United States and Canada, in part due to the influence of climate change. Not only are we seeing hazier skies in Minnesota, we’re experiencing more unhealthy air from wildfire smoke.
Knowing what to do when you see a tornado, or when you hear a tornado warning, can help protect you and your family. More information can be found at Tornadoes.

Drinking Water Annual Report highlights last year’s successes
Each year, during Drinking Water Week, the Minnesota Department of Health (MDH) releases its annual report on how well Minnesota’s 6,500-plus water systems are meeting federal Safe Drinking Water Act (SDWA) standards. The Minnesota Drinking Water Annual Report for 2024 (PDF), just released, notes that all federal health-based standards were met by over 97% of systems throughout 2024, according to the results of monitoring done in the past year.

Mold and Moisture
Mold can start to grow on interior building surfaces and furnishings if there is too much moisture. Eventually, the mold will damage the materials it is growing on and may cause health effects to occupants. Learn how mold can affect your health, how to control moisture and find mold inside your home, and how to remove mold at Mold and Moisture.

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.
