The number of Cyclospora infections confirmed by the Centers for Disease Control and Prevention continues to climb, with 13,895 illnesses logged compared to 10,468 a week ago.
The agency appears to be making headway in confirming suspected patients, though, with the number dropping to 10,455 compared to 12,255 a week ago. The CDC says its numbers come from 47 states and Puerto Rico. An independent count of all 50 states shows more than 28,000 patients with at least 688 hospitalizations and two deaths in Michigan.
The CDC is tracking a separate 15-state outbreak linked to iceberg lettuce sourced from a Taylor Farms growing operation in Central Mexico. The company recalled all of its iceberg lettuce from Central Mexico. For that outbreak the CDC has not updated its numbers from a week ago. At that time the agency was reporting 6,358 patients with hospitalizations of 278.
The number of infections this year is vastly higher than 2025 when a total of 1,180 cases were reported in the United States between May 1 and Aug.31.
The count for the 50 states this year, minus 12 who are not posting numbers, stands at 28,056. Michigan continues to have the most patients by far, reporting 12,485. The state is expected to update its count Aug. 13. Last year Michigan recorded 50 cases.
The other states with counts of more than 1,000 are Ohio with 4,900 compared to 76 in 2025; Indiana with 1,893 compared with 27 in 2025; and Missouri with 1,577 and none reported in 2025.
The Food and Drug Administration says it is not currently aware of any antimicrobial that would significantly minimize or prevent Cyclospora cross-contamination and be suitable for use on fresh-cut produce. It also says a wash-water process control is not a kill step, and that antimicrobials do not meaningfully reduce pathogens attached to produce or internalized in the tissue.
