US Health Officials Declare End to Record Cyclospora Outbreak
United States health authorities have officially closed the book on the largest cyclosporiasis outbreak in national history. The incident resulted in 12,883 recorded illnesses across 21 different states, with Michigan suffering the highest concentration of cases.

The massive scale of this public health event severely disrupted food supply chains and forced extensive federal product recalls. Despite exhaustive tracing efforts and facility inspections, the failure to identify the exact contamination vector leaves a significant gap in food safety tracking.
