Cyclospora: It Is Not Over Yet - US Count at 548 Cases

The mystery of the Cyclospora infection continues, putting workplaces at risk  from the disease.

The US Centers for Disease Control and Prevention (CDC) today reported nine more US Cyclospora infections, raising its case count to 548, but the total does not include 21 of the most recent cases that the TexasDepartment of State Health Services (TDSHS) has listed on its Web site. Those additions would bring the tally to 569.

The number of affected states remained at 19 (see CDC map below), but the CDC said that not all cases are confirmed to be linked to an outbreak in Iowa and Nebraska traced to a contaminated salad mix from Mexico. The states with by far the most cases are Texas, 220 (by the CDC's count); Iowa, 153; and Nebraska, 86.
The most recent illness onset was Jul 28, but most illness-onset dates are from the middle of June through early July, the CDC said. Of the 548 cases, 34 (6%) have required hospitalization.
Investigations have linked restaurant-related illness clusters in Iowa and Nebraska to a packaged salad mix from a Taylor Farms facility in Mexico, and this week the company voluntarily stopped shipping all of its leafy greens to the United States.
