Record Cyclosporiasis Outbreak Spurs Nationwide Recall of Taylor Farms Lettuce
7/24/2026, 9:08:55 PM
Core Event: Surge in Cyclospora Infections and Recall of Shredded Iceberg Lettuce
The CDC reported 4,173 laboratory-confirmed cases of cyclosporiasis in 41 states since May 1, 2026, with more than 7,400 additional cases under investigation. The outbreak has caused 308 hospitalizations and no deaths. A multistate cluster of at least 1,644 illnesses in Indiana, Kentucky, Michigan, Ohio and West Virginia was linked to shredded iceberg lettuce supplied by Taylor Farms de Mexico and served at Taco Bell. Taylor Farms issued a voluntary recall on July 17, 2026 covering lettuce sold under the Marketside brand at Walmart in 27 states.
Background & Context
Cyclosporiasis, caused by *Cyclospora cayetanensis*, typically peaks from May through August. The 2026 season has already surpassed the previous high of 4,703 cases in 2019, prompting intensified surveillance.
Timeline
- May 1, 2026 – CDC begins counting confirmed cases for the season.
- July 17, 2026 – Taylor Farms recalls the implicated lettuce.
- July 18–19, 2026 – FDA reports, then retracts, a false-positive test for Cyclospora in a Taylor Farms sample.
- July 21, 2026 – CDC updates totals to 4,173 confirmed cases and >7,400 probable cases.
- July 22–23, 2026 – Kansas reports 289 linked cases; national probable cases exceed 7,400.
Data & Statistics
- Confirmed cases: 4,173
- Probable cases: >7,400
- Hospitalizations: 308
- Deaths: 0
- States reporting: 41
- Median age: 44; 56 % female
- Travel-linked cases: 767
State health departments cite combined totals exceeding 11,000 suspected infections, indicating a reporting gap with CDC data.
Official Statements & Responses
Taylor Farms said, “To be clear, at this moment, FDA has not identified a single positive product test result for Cyclospora.” HHS Secretary Robert F. Kennedy Jr. asserted the outbreak is “under control” and that surveillance programs remain intact.
Criticism & Opposition
Mexico’s Secretary of Health David Kershenobich disputed U.S. findings. Kennedy faced criticism over alleged cuts to CDC’s FoodNet program, which he denied, stating “Those criticisms are invalid. We’ve had no cuts in our surveillance program.”
On-the-Ground Reports
Michigan and Ohio health officials continue to receive the bulk of new reports; Michigan alone counts over 7,000 cases. Smaller outbreaks linked to parsley and cilantro in North Carolina remain under investigation.
Conflicting Reports & Gaps
- CDC vs. state counts: CDC’s 4,173 confirmed tally contrasts with state-reported totals above 11,000, reflecting differing case definitions and reporting lags.
- FDA test result: The July 18 positive result was later classified as a false positive, briefly clouding source attribution.
Why It Matters
The outbreak highlights vulnerabilities in the fresh-produce supply chain, especially for items that cannot be fully decontaminated by washing, and underscores the difficulty of real-time surveillance for parasites with long incubation periods.
What’s Next
The CDC will keep investigating the probable cases and urges consumers to discard recalled lettuce and follow CDC guidance on produce handling. Federal agencies plan to update guidance as additional traceback data become available.
