Leafy Greens Implicated in Michigan Cyclospora Surge: 3,309 Cases Reported

Leafy Greens Under Scrutiny as Michigan Faces Cyclospora Crisis

Michigan health officials are racing to pinpoint the source of a massive Cyclospora outbreak that has already produced ↑ 3,309 confirmed cases statewide, according to the Michigan Department of Health and Human Services. Patients report severe watery diarrhea, abdominal cramps and nausea, symptoms that mirror those seen after the recent pandemic wave. Interviews with over 1,000 affected individuals point to leafy greens—particularly lettuce and salad mixes—as the most likely vehicle.

“The pattern is unmistakable,” said an MDHHS epidemiologist, “the majority of sickeners consumed raw greens within days of falling ill.”

So far, ↓ 44 patients have required hospitalization, a figure that, while small, underscores the seriousness of the pathogen. The outbreak dwarfs the state’s typical annual tally of about 50 cases, a spike that has drawn attention from federal agencies. Reuters reports that the CDC is coordinating a multi‑state investigation, while AP News notes that similar outbreaks have been linked to imported produce in the past. Authorities urge consumers to wash all fresh produce thoroughly and consider cooking greens when possible.
