Pittsburgh, PA, August 26, 2026 —
An escalating Cyclospora outbreak has now impacted 48 states and the District of Columbia, marking it as the largest foodborne illness incident in recent U.S. history. As of the latest reports, confirmed cases have surged to 17,180.
The widespread nature of the outbreak is further underscored by the number of individuals requiring hospitalization. A total of 922 hospitalizations have been linked to the Cyclospora infection. Tragically, two deaths have also been confirmed in connection with the outbreak.
While Michigan currently reports the highest number of cases, emerging data on the growth rate of new infections suggests a potential slowdown in the outbreak’s progression. However, the Centers for Disease Control and Prevention (CDC) cautions that the official figures may not fully represent the total number of people affected. The CDC notes that actual numbers could be higher due to unconfirmed and unreported cases.
The specific source of the Cyclospora contamination has not been publicly detailed. Further information regarding the investigation into the outbreak’s origin is anticipated.
