A parasitic illness is spreading across the United States this summer, and after weeks of investigation, federal health officials still cannot identify the specific food responsible for making people sick. The frustrating lack of a recall announcement is not a failure of urgency — it is a reflection of how uniquely difficult this particular parasite is to track.
The Centers for Disease Control and Prevention has confirmed 145 domestically acquired cases of Cyclospora cayetanensis infection in 17 states, with illness onset dates from May 1 through June 7, 2026. Three people have been hospitalized. No deaths have been reported. But the case count is almost certainly a substantial undercount, and the absence of a specific food recall does not mean the outbreak is over.
