Legionnaires' disease at Maple Grove assisted living facility investigated

- The Minnesota Department of Health is investigating two cases of Legionnaires’ disease confirmed in residents at the SilverCreek on Main memory care and assisted living facility in Maple Grove. The first resident’s symptoms began Aug. 22, and the second resident’s symptoms began Sept. 12. 

MDH is working with SilverCreek to identify possible sources for the Legionella bacteria. SilverCreek has retained its own expert consultant to begin immediately evaluating and addressing findings. Early evidence indicates the source of the Legionella bacteria is most likely within the building water system, though an exact source must still be determined. An assessment of the facility’s plumbing system is underway.

MDH is recommending SilverCreek take a number of protective measures to minimize the chance for more residents to be exposed to Legionella bacteria, based on CDC guidelines. The facility has notified its residents and their families about the Legionnaires’ cases and the CDC recommendations. The recommendations apply only to residents, people visiting and workers at SilverCreek on Main.

MDH is working with Hennepin County Public Health, the City of Maple Grove and other partners to investigate the two cases of Legionnaires' at SilverCreek. City of Maple Grove water meets water quality standards, according to the health department.

Legionnaires’ disease is a type of bacterial pneumonia. Symptoms include fever, fatigue, headache, muscle aches, chills, shortness of breath, loss of appetite and coughing. Legionnaires’ disease is spread by inhaling the fine spray (aerosols) from water sources containing Legionella bacteria. It is not spread from person to person. Minnesota typically sees 50-60 cases in a year. The last major outbreak took place in 2016 in Hopkins.

Most people exposed to Legionella do not develop Legionnaires’ disease. People over the age of 50, smokers or those with certain medical conditions including weakened immune systems, diabetes, chronic lung disease or other chronic health conditions are at an increased risk. If you have concerns about possible exposure, contact your health care provider.

Statement from SilverCreek

"Silver Creek is working in partnership with the Minnesota Department of Health, Hennepin County and a team of experts to determine the source of the Leigionella that has impacted two residents at our property. We are in the process of a full environmental assessment the potential sources with outside experts and public health officials. Early indications are that the issue is isolated to a small area of the property.  As a precaution we have closed the pools on the property and are advising residents of alternative sources of water as well as no showers, and providing bottled water for drinking and oral care. We will take all necessary precautions, including further water restrictions for residents as advised with the Minnesota Department of Health and Hennepin County.  Our precautions are following the Center for Disease Control Guidelines. At this time we believe the risk to additional residents is minimal, however we are taking many extra precautions to ensure the safety and health of our residents."
