The Cyclospora Contaminated Produce Outbreak has now reached 10,468 laboratory-confirmed cases in 47 states, the Centers for Disease Control and Prevention said in its Aug. 4 update. The count has climbed by more than 3,700 since the CDC’s July 28 report, and it includes 517 hospitalizations and two deaths.
For anyone searching the outbreak now, the reason is simple: it is no longer a regional event. Cyclosporiasis, caused by the parasite Cyclospora cayetanensis, can bring watery, frequent and sometimes explosive diarrhea, and the CDC said it is still tallying cases that began on or after May 1 in people who had not traveled internationally within the 14 days before becoming ill.
Michigan is the center of the outbreak’s biggest cluster, even though the CDC’s national count is lower than what the state reported on Aug. 4. The CDC put the total at 10,468 lab-confirmed cases; Michigan said it had more than 11,000 cases and the first two deaths tied to the outbreak. That gap matters because the federal total includes only cases that have cleared laboratory confirmation under a reporting system that often lags illness by about six weeks.
The illnesses have been linked to iceberg lettuce grown by Taylor Farms in central Mexico, and the company initiated a recall on July 17. Cases tied to the lettuce outbreak have been confirmed in Illinois, Indiana, Kansas, Kentucky, Michigan, Ohio, Oklahoma, Pennsylvania and West Virginia, while Washington, DC has also reported a handful of cases. By Aug. 4, only Delaware, Hawaii and Montana had not reported cases.
That pattern leaves federal health authorities with a problem that is bigger than one recalled product and not yet neatly contained. The CDC said it believes it is investigating multiple separate outbreaks, but the national picture is already clear enough: the outbreak has spread across nearly the country, the case total is still rising, and the source question is now less about whether the lettuce was involved than which contamination step made so many people sick.
