U.S. Cyclosporiasis Outbreak Swells Amid Lettuce Recall
8/19/2026, 9:21:08 AM
Surge in Cyclospora Cases Linked to Contaminated Iceberg Lettuce
Since early May, the United States has experienced a historic rise in cyclosporiasis, a gastrointestinal illness caused by *Cyclospora cayetanensis*. The CDC reported 15,716 laboratory-confirmed cases across 47 states, D.C., and Puerto Rico as of August 18. Hospitalizations total 828, and two deaths have been confirmed. The outbreak is anchored to a multistate contamination of processed iceberg lettuce sourced from a Taylor Farms facility in central Mexico, which was voluntarily recalled on July 17.
Background & Context
The first cluster emerged in Michigan in early May, where officials traced thousands of illnesses to the imported lettuce. Subsequent investigations linked the same product to additional cases in 17 states, creating one of the largest food-borne illness events in recent U.S. history. While the primary outbreak appears to be slowing, the FDA continues to monitor smaller, source-unknown clusters that have risen since July.

Official Statements & Responses
- The administration has characterized the nationwide spread as “contained.”
- Health Secretary Robert F. Kennedy Jr. told reporters the situation is “under control.”
- The CDC advises anyone with prolonged watery diarrhea, cramping or fever to seek medical care and request specific Cyclospora testing, noting that routine stool exams may miss the parasite.
- Federal officials emphasize that recalled lettuce products are past their best-by dates and should no longer be available in stores or restaurants.
Verbatim Quotes
- “You can't remove this parasite 100 percent from washing, but you can reduce the numbers by washing in cold running water, washing your hands before and after, and cleaning your cutting boards,” — James Rogers, food-safety expert
Conflicting Reports & Gaps
- Total case counts differ between agency updates: the CDC’s August 18 figure of 15,716 exceeds the 13,895 cases reported in an earlier surveillance summary. The discrepancy reflects ongoing confirmations and inclusion of probable cases pending analysis.
- Florida reporting shows a mismatch: the state’s Department of Health listed 417 confirmed or probable cases, while the CDC’s national system recorded a lower number. Different reporting criteria and update schedules create divergent tallies.
- Source attribution for many newer clusters remains unknown, and the FDA has not yet linked specific states to the latest outbreaks.
What’s Next
Federal investigators continue to examine additional clusters with unidentified sources. The CDC and FDA are coordinating traceback efforts to determine whether other produce items share the contamination pathway. Consumers are urged to follow CDC guidance—cooking produce to 158 °F, washing under running water, and practicing thorough hand hygiene—while the recall remains in effect.
