Federal investigators traced a record cyclospora outbreak to shredded iceberg lettuce shipped from central Mexico and served at Taco Bell, then watched the case count explode past 11,000.
Story Snapshot
- Food and Drug Administration traced the source to Taylor Farms de Mexico’s iceberg lettuce used at Taco Bell.
- Taylor Farms removed central Mexico iceberg lettuce and initiated a recall affecting restaurants and retail.
- Centers for Disease Control and Prevention reports outbreaks across many states tied to processed iceberg lettuce.
- Officials expanded investigations as the outbreak spread to additional states.
What Investigators Found And Why It Matters
The Food and Drug Administration said its traceback work converged on a single supplier: Taylor Farms de Mexico, which provided shredded iceberg lettuce used at Taco Bell locations where many sick people ate before falling ill.
The Centers for Disease Control and Prevention reported that epidemiology and traceback linked processed iceberg lettuce from central Mexico to the illnesses.
This pattern fits how cyclospora outbreaks often unfold. Fresh produce carries risk because people eat it raw, with no heat step to kill parasites.
Taylor Farms de Mexico pulled all iceberg lettuce sourced from central Mexico from the United States market and began a recall that reached both restaurant supply and certain retail items, including some store brands.
Retailers and distributors also moved to remove affected product lots. Federal updates noted that best-by dates have now passed for recalled items, a sign that contaminated lettuce should no longer sit on shelves or in coolers. Case counts can still rise because cyclospora symptoms can appear days to weeks after exposure.
How The Outbreak Grew Across States
Federal health officials first identified shredded iceberg lettuce at Taco Bell in five states as a source. The investigation then widened as cases appeared in more places, and the outbreak expanded to additional states.
The Centers for Disease Control and Prevention mapped illnesses tied to processed iceberg lettuce exposures in many states, matching what investigators saw in patient food histories and distribution records. Reported illnesses surged into the thousands as interviews and lab-confirmed cases accumulated across the season.

The scale is large but not mysterious. Cyclospora thrives in warm, wet conditions, and contamination can occur on farms, in fields, or during processing. Modern supply chains pool produce from many lots and send it nationwide within days.
By the time people get sick and call doctors, the lettuce they ate is long gone. That is why traceback, not a single found sample, often cracks these cases. The Food and Drug Administration emphasized the supplier convergence as the key link.
What To Do Now: Practical Steps That Work
Consumers who think they ate recalled iceberg lettuce and have lasting diarrhea, stomach cramps, or fatigue should talk to a doctor. Cyclospora does not respond to most common stomach bug treatments. Doctors can order tests and prescribe a targeted antibiotic.
People who bought bagged salads should check brand, lot, and dates against recall notices. The Food and Drug Administration urged cleaning and sanitizing any surfaces or bins that touched recalled greens to avoid cross-contamination as people restock with safe produce.

Restaurants and retailers should document suppliers, lots, and distribution dates and keep that data handy for investigators. Food businesses that used Taylor Farms de Mexico iceberg lettuce during the recall window should maintain cleaning logs and disposal records.
That paper trail speeds tracebacks and protects customers. The long game requires hard fixes upstream: clean water sources for irrigation and washing, worker hygiene, and field sanitation. Prior outbreaks linked to leafy greens and salad mixes show this is a repeatable playbook when controls break down.
Why This Traceback Fits A Known Pattern
Public health teams have linked cyclospora outbreaks to produce for decades, including raspberries, cilantro, and mixed salads. Reviews show most documented cyclospora outbreaks worldwide come from fresh produce eaten raw. In some seasons, investigators link clusters to lettuce varieties without ever finding the exact bag.
They still act because the distribution math, exposure histories, and timing line up. The Centers for Disease Control and Prevention and Food and Drug Administration both describe this lettuce-linked outbreak using that same set of tools and conclusions.
