Legionnaires outbreak that sickened 14 traced to Grand Rapids, Minn., water supply
A cluster of 14 cases of Legionnaires’ disease in Grand Rapids, Minn., has been traced to the municipal water supply, a state health investigation has found.
City authorities said Monday that they plan to flush and disinfect the water system to reduce risks of the disease, which is caused by inhalation of water droplets containing the Legionella bacteria. The disease is fatal in as many as one in 10 cases. While no one has died in this outbreak, 11 people were hospitalized.
Thirteen infected individuals had been in two buildings in a small area of Grand Rapids, while the fourteenth had been in the vicinity, said Trisha Robinson, epidemiologist supervisor for the Minnesota Department of Health’s waterborne diseases unit. Genomic sequencing of lab samples from the patients tied their infections to the same bacterial strain.
Investigators looked for other possible sources, but exposure to the city water supply was the only risk factor all 14 people had in common, she said.
Infections rarely occur through drinking water. It usually happens when people inhale water droplets from a shower, faucet, spray bottle or power washer, she said. People aren’t at risk if they drink water in Grand Rapids, but should use distilled or filtered water for aerosolizing devices such as CPAP machines.
The state began investigating shortly after the first cases were identified in Grand Rapids in April 2023. While Legionnaires is more common in warmer months, the cases in this outbreak have occurred sporadically across 2023, and include two illnesses in 2024.
Legionella tends to grow and spread in warmer, stagnant water, especially if it isn’t treated with chemicals such as chlorine. Grand Rapids operates one of the few community water systems in Minnesota without chlorination, which is allowed for community wells that draw from groundwater, according to the state health department.
While a chlorination system is now “being looked into” as one strategy to confront the outbreak, it can be tricky to introduce the disinfectant into a previously unchlorinated system, said Julie Kennedy, Grand Rapids Public Utilities general manager. “Our approach needs to be methodical to ensure we avoid any additional health, safety or distribution system complications. We will be providing local updates and customer notices as that plan develops.”
Minnesota reported 134 Legionnaires cases and six deaths in 2023 — most of which occurred in isolation and didn’t trigger state investigations. The Grand Rapids outbreak is a major one for Minnesota, but is not the largest, Robinson said. More than 20 Legionnaires’ cases and one death were linked to cooling towers at a beverage plant in Hopkins in 2016.
Risks of health problems from Legionnaires are elevated for people who are 50 or older, smoke, and have existing chronic health conditions. The health department has urged doctors in Grand Rapids to watch for suspicious symptoms, and for patients to seek medical attention if they develop pneumonia — which could indicate Legionnaires.
A 19-year-old driver trying to get around slower vehicles collided head-on with an SUV in Wright County and killed one person and injured several others, officials said Thursday.
SUV passenger Janice Evelyn Johnson, 92, of Arden Hills, died Monday at HCMC from injuries she suffered in the collision on Oct. 22 in Monticello Township on County Road 37 near County Road 12, the Sheriff’s Office said in a search warrant affidavit filed in Hennepin County District Court.
The driver and two other people in the SUV survived their injuries, according to the affidavit, which the Sheriff’s Office filed to collect Johnson’s medical records at HCMC as part of its investigation.
According to the affidavit:
Deputies arrived at the crash scene and spoke with the car’s driver, Christian Kabunangu, of Brooklyn Park, who said he was heading west on County Road 37 and found himself behind two vehicles traveling below the speed limit.
“He was late for work, so he decided to pass them,” the affidavit read. Kabunangu said he saw the oncoming SUV and estimated it was about a half-mile down the road.
As he attempted to pass one of the slower vehicles, he explained, the other driver “sped up, preventing him from getting back into the westbound lane,” the filing continued.
As the Honda drew near, he swerved to the left, but the SUV did the same and they collided.

University of Minnesota researchers find that native plants can beat invasive buckthorn on their own turf.
If the invasive buckthorn that is strangling the life out of Minnesota’s forest floor has a weakness, it is right now, in the shortening daylight of the late fall.
With a little help and planning, certain native plants have the best chance of beating buckthorn back and helping to eradicate it from the woods, according to new research from the University of Minnesota.
The sprawling bush has been one of the most formidable invasive species to take root in Minnesota since it was brought from Europe in the mid-1800s. It was prized as an ornamental privacy hedge. All the attributes that make buckthorn good at that job — dense thick leaves that stay late into the fall, toughness and resilience to damage and pruning, unappealing taste to wildlife and herbivores — have allowed it to thrive in the wild.
It grows fast and thick, out-competing the vast majority of native plants and shrubs for sunlight and then starving them under its shade. It creates damaging feedback loops, providing ideal habitat and calcium-rich food for invasive earthworms, which in turn kill off and uproot native plants. That leaves even less competition for buckthorn to take root, said Mike Schuster, a researcher for the university’s Department of Forest Resources.
When it takes over a natural area, buckthorn creates a “green desert,” Schuster said. “All that’s left is just a perpetual hedge, with little biodiversity.”
Since the 1990s, when the spread became impossible to ignore, Minnesota foresters, park managers and cities have spent millions of dollars a year trying to beat it back. They’ve used chainsaws and trimmers, poisons and herbicides, and even goats for hire. The buckthorn almost always grows back within a few years.
It’s been so pervasive that a conventional wisdom formed that buckthorn seeds could survive dormant in the soil for up to six years. That thought has led to a sort of fatalism: even if the plant were entirely removed from a property there would be a looming threat that it would sprout back, Schuster said.
But there is nothing special about buckthorn seeds. They only survive for a year or two.
Eden Prairie Eagles (6-3) at Maple Grove Crimson (9-0), 7 p.m.
Jim says: Maple Grove faithful are understandably jittery about getting Eden Prairie this early in the playoffs, but they should trust their eyes. The Crimson are loaded, with quality playmakers at every turn, like safety/receiver Dylan Vokal. Eden Prairie is built for games like this, but while the Eagles will keep things tight for awhile, Maple Grove will pull away in the second half, leading to a seismic sigh-of-relief from northwest metro. The pick: Maple Grove 35, Eden Prairie 21
David says: Eden Prairie’s time, however decorated an success-filled, is done and over. Provided the Crimson are able to take it. Maple Grove is capable of success as long as players don’t make the moment too big. Former coach Matt Lombardi cracked the code. What about his replacement, Adam Spurrell? The pick: Maple Grove 21, Eden Prairie 14
Edina Hornets (7-2) at Eagan Wildcats (5-3), 7 p.m.
Jim says: On paper, this leans toward an Edina victory. The Hornets have top-end talent on offense (QB Mason West, WR Meyer Swinney), an under-appreciated defense and a season-opening 35-14 victory over Eagan. But the Wildcats are resilient and don’t back down from anyone. Quarterback Brooklyn Evans is adept at running the Wildcats option offense and will keep them in the game. The pick: Edina 28, Eagan 15
David says: Tempting as it is to pick against Edina and revel in another office cake party, let’s go with the Hornets in this one. Expect an improved Eagan team to keep Edina within reach, however. The pick: Edina 21, Eagan 20
Alexandria Cardinals (7-2) at Moorhead Spuds (9-0), 7 p.m.
Jim says: Alexandria came oh-so-close to beating Moorhead on Oct. 11, falling 36-34 when a game-winning field goal went wide-left. While the Cardinals hoped for this rematch, Moorhead has the look of a team on a mission. Outside of the head-to-head matchup, Moorhead dominated every other opponent with a series of 30-point plus victories. No one mashes the Spuds. The pick: Moorhead 44, Alexandria 34
David says: The Game of the Year, Part II. Only thing to make this more juicy would be an upset. Is Alexandria up to that task? I don’t have the courage to go out on that limb in this space. The pick: Moorhead 42, Alexandria 24
Andover Huskies (7-2) at Elk River Elks (8-1), 7 p.m.
Jim says: Another highly anticipated rematch. Andover handed mistake-prone Elk River it’s only loss, 47-31, on Sept. 20. With three lost fumbles, Elks’ coach Steve Hamilton called it the worst game they’ve played in five years. You can bet they’re itching to prove they’re better than they showed that night. The pick: Elk River 49, Andover 37
David says: Bet the over when these two teams clash. Andover’s quarterback Joseph Mapson is a much more polished and proven signal caller that he was in late September. The Pick: Andover 49, Elk River 48.
