Overview
- The Centers for Disease Control and Prevention reported 17,180 confirmed cyclosporiasis cases nationwide as of Aug. 24, with 922 hospitalizations and two deaths recorded.
- Federal traceback work linked the biggest cluster to iceberg and shredded lettuce processed by Taylor Farms de Mexico, and recalled lots are past their best‑by dates and believed to be off the market.
- Investigators face limits that slow confirmation and attribution because Cyclospora must sporulate outside the body, cannot be easily cultured, and requires specialized stool testing and lengthy interviews.
- Clinicians and public health officials say the parasite causes prolonged watery diarrhea and dehydration, that washing produce reduces but does not eliminate risk, and that cooking to 158°F reliably kills Cyclospora.
- The outbreak has driven millions of U.S. households to cut back on pre‑bagged salad purchases, forced retailers and restaurants to change sourcing, and left federal teams probing several other unlinked clusters.
