Two cases of Legionnaires’ disease reported at the SilverCreek on Main facility in Maple Grove are being investigated by state, county, and local partners, according to a press release from the Minnesota Department of Health (MDH).

SilverCreek on Main provides memory care, assisted living and independent living services.

Symptoms for the first resident began to appear Aug. 22 followed by a second resident Sept. 12. Both individuals were hospitalized and recovering, according to MDH.

Legionnaires’ disease is a type of bacterial pneumonia and is spread by inhaling the fine spray (aerosols) from water sources containing Legionella bacteria. It is not spread from person to person. There are approximately 50-60 cases a year in Minnesota,

“MDH is working with SilverCreek to identify possible sources for the Legionella bacteria. SilverCreek has retained an expert consultant to begin immediately evaluating and addressing findings. Available evidence indicates the source of the Legionella, the bacteria that causes Legionnaires’ disease, 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,” according to the (MDH) press release.

SilverCreek on Main has notified residents and their families about protective measures to minimize Legionella bacteria exposure and started implementing them.  

“The recommendations apply only to residents, people visiting and workers at SilverCreek on Main,” according to MDH. “City of Maple Grove water meets water quality standards.”

The Hennepin County Public Health and the city of Maple Grove are working with Minnesota Department of Health to investigate the cases.

Most people exposed to Legionella do not develop Legionnaires’ disease, MDH stated.
