Federal and state investigators traced a nationwide Cyclospora surge to shredded iceberg lettuce from Taylor Farms de Mexico served at Taco Bell, then watched cases climb past 11,000 as the outbreak spread to more states.
Story Snapshot
- Investigators linked illnesses to shredded iceberg lettuce from Taylor Farms de Mexico.
- Taylor Farms recalled iceberg lettuce sourced from central Mexico and pulled it from the U.S. market.
- The Centers for Disease Control and Prevention reported spread across many states as tracking widened.
- Taco Bell said it stopped using the implicated lettuce during the response window, according to Food and Drug Administration updates.
How the Investigation Found the Lettuce Link
Food and Drug Administration investigators ran a traceback from sick customers’ meals to a common source. The paths converged on shredded iceberg lettuce from Taylor Farms de Mexico that supplied Taco Bell in several states.
The Centers for Disease Control and Prevention added epidemiologic evidence that matched ordering and exposure histories, which is the standard playbook for produce outbreaks when the food is perishable and often gone before testing can begin. Federal updates described the lettuce as the likely vehicle, based on strong, overlapping lines of data.
Taylor Farms de Mexico launched a voluntary recall on July 17, removing all iceberg lettuce sourced from central Mexico from the U.S. market. The recall included retail items and product distributed to restaurants.
The company acted as the Food and Drug Administration and the Centers for Disease Control and Prevention widened the case definition and notified retailers and food service operators. Public health alerts told consumers to check refrigerators, toss recalled bags, and clean surfaces that touched the lettuce.

Where and How Big This Outbreak Has Grown
The Centers for Disease Control and Prevention mapped cases across a growing list of states as health departments connected local reports to the national cluster. Early counts began in a five-state cluster tied to Taco Bell locations.
Investigators later saw spread to more regions as traceback and interviews caught up with the exposure window. Reported illnesses have exceeded 11,000 as the summer wave peaked and more people sought care and testing. Hospitalizations occurred, but most patients recovered with treatment and time.
Officials said best-by dates for the recalled lettuce have passed, which means remaining risk comes from secondary exposure, like cross-contaminated surfaces, and from people who ate the product before the recall but developed symptoms later.
Cyclospora often causes a delayed onset of watery diarrhea, stomach cramps, nausea, and fatigue. The infection can last weeks without antibiotics. Doctors can treat it, but many cases take time to diagnose because symptoms look like other stomach bugs. That lag tends to inflate the tail of case counts.
Why Cyclospora Keeps Targeting Produce
Leafy greens, herbs, and berries often carry Cyclospora in outbreaks because they are eaten raw and lack a cooking step that kills parasites. Farms pool and process produce from many fields, then ship it nationwide.
By the time a pattern of illness appears, the food is gone from shelves. Traceback then does the heavy lifting, linking meals, purchase records, and distribution maps to one source. Reviews show produce vehicles in most documented Cyclospora outbreaks around the world.
Past U.S. outbreaks tied to lettuce and salad mixes show the same pattern. Investigators linked restaurant clusters to single lots or common processors, including events that involved bagged mixes with iceberg and romaine lettuces.
The Food and Drug Administration’s outbreak handbook explains that clear convergence in traceback can carry the case even when no leftover food tests positive, because perishable items move fast through the supply chain. That is what happened here, with convergence on Taylor Farms de Mexico’s shredded iceberg lettuce.
What Restaurants and Consumers Did Next
Taco Bell told investigators it stopped using implicated Taylor Farms de Mexico lettuce as of July 17, which lined up with the recall and the supply chain pause. Retailers and distributors acted on recall notices and removed labeled bags.
Public health messages urged customers to throw out recalled items and sanitize cutting boards, drawers, and countertops. That basic step breaks chains of contamination in home kitchens. Consumers who ate recalled lettuce and then developed symptoms were told to seek care and ask about Cyclospora testing.

The Food and Drug Administration and the Centers for Disease Control and Prevention used the tools they had, and industry pulled product quickly.
The next step is stricter field sanitation, cleaner wash water, and faster digital trace records, so one bad lot does not sideline a whole category or frighten millions of shoppers.
