Michigan health officials reported 600 additional cyclosporiasis cases Today, pushing the state’s total to 7,171, a 9% jump from Tuesday’s count of 6,571. The Michigan Department of Health and Human Services said 102 people have been hospitalized as of last Thursday, though no deaths have been reported.
The state typically sees only about 50 confirmed cyclosporiasis cases in a given year, making this year’s total dramatically higher than usual. Michigan and Ohio continue to account for the bulk of the broader national outbreak, according to the CDC, which has separately confirmed thousands of cases across dozens of states as part of the investigation Rolling Out has previously covered.
Why Michigan’s count looks higher than the CDC’s national figure
At first glance, Michigan’s single-state total of 7,171 appears to outpace the CDC’s national count of 4,173, a gap that comes down to how each level of government defines and reports a case. The CDC’s figure reflects only strict, laboratory-confirmed cases nationwide. Michigan’s tally, by contrast, includes both confirmed and probable cases, meaning residents showing classic symptoms after eating recalled lettuce but who haven’t yet completed the slower lab culture process.
That distinction matters at a national scale too. Beyond the 4,173 lab-confirmed cases, the CDC is tracking roughly 7,400 additional suspected cases still awaiting full validation, pushing the combined national total past 11,000, an unprecedented spike compared to the roughly 2,700 cases reported across the entire country in all of 2025. Michigan and Ohio make up the vast majority of that suspected case pool, which explains why the state’s real-time count can appear larger than the federal government’s more conservative, confirmed-only figure.
County breakdown shows concentrated spread
Cases have now been reported in 65 of Michigan’s 82 counties. As of last week, Wayne County led the state with 582 cases, followed by Washtenaw County with 474, Oakland County with 396 and Ingham County with 393. Other counties reporting notable numbers include Shiawassee (278), Livingston (180), and Clinton (112), reflecting how widely the illness has spread beyond its initial hotspots.
Health officials update county-by-county figures once a week, typically on Thursdays, meaning the most current statewide total may already reflect additional cases not yet broken down by location.
State health officials renew guidance on lettuce safety
Michigan health department spokesperson Lynn Sutfin said the agency continues to recommend that residents purchase whole heads of lettuce rather than pre-washed, bagged lettuce or pre-mixed salad kits while the investigation remains active. That guidance lines up with the broader food safety recommendations already in place following the Taylor Farms lettuce recall tied to the outbreak.
Sutfin’s comments reflect an effort by state officials to keep residents informed as case numbers continue climbing week over week, even as questions remain nationally about the exact source and scope of contamination. Michigan residents experiencing symptoms are encouraged to contact a health care provider, particularly given how quickly the state’s numbers have grown in recent days.
