About two dozen suspected cases of E. coli have been reported in a Chippewa reservation in northeastern Minnesota, sending two people to the hospital and prompting an investigation by the Minnesota Department of Health.
Early testing indicates that the contamination is not linked to the statewide outbreak reported last week.
More than a handful of cases have been confirmed as E. coli, but the final numbers will fluctuate as health officials receive lab results, said April Bogard, environmental health supervisor at the department.
Community members from the Fond du Lac Band began reporting symptoms late last week, and two patients were briefly hospitalized, said Chuck Walt, executive director of tribal programs for the reservation.
"The good news is we haven't had any new cases reported, so it seems like this is on the downward slide," Walt said.
The Health Department is interviewing patients and seeking the source of the outbreak, which may have been linked to the mishandling of leftover food.
"The summer time is when we have picnics and powwows and lots of outdoor community events where food is served," Walt said. "Those tend to be areas that people suspect when you get these types of foodborne illnesses."
Health officials are urging the public to discard leftovers from picnics and other events and to report any symptoms to the department.
