Ten cases of E. coli have been identified from customers who ate hamburgers at locations of the Red Cow restaurant chain, and one case was found at Hen House Eatery in downtown Minneapolis, the Minnesota Department of Health announced Friday.
Health Department: E. coli infections traced back to Red Cow restaurants and Hen House Eatery
Authorities have identified 10 cases at Red Cow locations and one case at Hen House. Both restaurants have made product changes.
The ground beef product connected to those infections was also distributed to other unidentified establishments, according to the Health Department. Additional cases from other locations could be identified, and other potential cases were already under investigation.
Red Cow has a total of six locations in Minneapolis, St. Paul, Wayzata and Rochester.
The confirmed cases involve meal dates from Oct. 31 through Nov. 7, and illness onset dates from Nov. 4 through Nov. 9, according to the department. Those affected range in age from 9 to 70 years, and two of them have been hospitalized.
Red Cow and Hen House Eatery owners are fully cooperating with the investigation and have already made product changes to prevent further illness, the department said.
Symptoms of E. coli typically include stomach cramps and diarrhea, often with bloody stools. Illness can set in anywhere from one to eight days after exposure. About 5% of cases can lead to severe complications such as acute kidney failure.
Veteran journalist Caroline Lowe, who has followed the case closely, said it’s the first known law enforcement activity in the case since 2017.
