The Lettuce Was Recalled in July. The Case Count Reached 11,458 This Week.

The Count

The CDC reported on August 27 that a cyclospora outbreak linked to iceberg lettuce has now sickened 11,458 people across 20 states, an increase of 528 cases in one week. At least 495 people have been hospitalized. Two people have died, both in Michigan.

Georgia, Tennessee and Texas were added to the list this week. Nationwide, 17,180 cyclosporiasis cases have been reported in 2026 overall.

Why the Number Keeps Climbing After the Recall

The source was traced to iceberg lettuce grown in central Mexico and supplied by Taylor Farms de Mexico. A recall covering all central-Mexico-sourced iceberg was issued July 17. Affected brands included Taylor Farms shredded iceberg and Marketside, sold at Walmart.

The product is off shelves and past its best-by dates. The case count is still rising because cyclospora reporting runs about six weeks behind illness onset. Confirmed onsets in this outbreak run from June 14 to August 15. The CDC states plainly that the true count is higher than the reported one.

The Test Most People Do Not Get

This is the actionable part, and it is easy to miss. Cyclospora is a parasite, not a bacterium, and standard stool panels do not detect it. A physician has to order testing for cyclospora specifically.

The illness produces watery diarrhea, cramping, nausea and fatigue that can persist for weeks or recur in cycles, and it does not resolve on its own the way most foodborne illness does. It requires a specific antibiotic. People who have been unwell for weeks after eating shredded iceberg since mid-June, and who were told their tests came back clear, are the group most likely to still be undiagnosed.

What the Six-Week Lag Means for September

Onsets recorded through August 15 will continue arriving in the reporting system into late September. The number will keep going up for several weeks after the outbreak itself has ended, which is a reporting artifact rather than new exposure. That distinction matters for anyone reading the weekly updates and concluding that contaminated product is still in circulation.
