Federal investigators traced a nationwide stomach parasite outbreak to shredded iceberg lettuce tied to a single supplier, and the case count keeps climbing.
Story Snapshot
- Food and Drug Administration traced the outbreak to Taylor Farms de Mexico’s iceberg lettuce.
- Taco Bell said it stopped using that lettuce on July 17, and a recall followed.
- The outbreak spread across multiple states with thousands ill, according to federal updates.
- Leafy greens and other raw produce often drive cyclospora outbreaks, research shows.
Traceback Identifies One Supplier And A Common Ingredient
The Food and Drug Administration reported its investigation “identified convergence on a single supplier, Taylor Farms de Mexico,” after interviewing sick people and mapping where they ate and shopped. The common thread was shredded iceberg lettuce served at restaurants, including Taco Bell locations visited before illness.
Traceback uses receipts, shipping records, and lot codes to follow ingredients back through distributors to a processor and fields. The Food and Drug Administration said the trace pointed to Taylor Farms de Mexico.
Taco Bell told investigators it stopped using lettuce from Taylor Farms de Mexico on July 17. On that same date, Taylor Farms de Mexico announced it would remove iceberg lettuce from central Mexico from the United States market.
The recall covered certain retail packs and foodservice shipments. Federal updates noted the action as part of outbreak control while state partners tracked new cases and exposure histories.
Case Counts Grow As States Report New Illnesses
Public health teams logged thousands of illnesses across many states as reports came in from clinics and labs. The Centers for Disease Control and Prevention mapped the spread and linked cases to processed iceberg lettuce from Taylor Farms de Mexico.
The agency’s location tracker showed affected states rising over time as more interviews tied back to the same ingredient chain. Reported hospitalizations rose as well, which is common when clusters expand across regions.

State and federal investigators said the recall “best by” dates have now passed at retail. That helps cut new exposures, but it does not erase illnesses that began earlier.
Cyclospora infections often show up late because people wait to seek care, testing takes time, and cases are logged after confirmation. This lag makes the outbreak look like it grows even after the suspect food is gone from shelves or restaurants.
Why Cyclospora Hits Raw Produce And Why That Matters Now
The parasite behind this outbreak, Cyclospora, spreads through food and water in places where sanitation gaps allow contamination. Fresh produce is a frequent vehicle because people eat it raw. No cooking step means no kill step.
Reviews of past events show leafy greens, salad mixes, raspberries, basil, and cilantro behind many outbreaks in several countries. That pattern matches the Food and Drug Administration and Centers for Disease Control and Prevention findings in this case.
Traceback, not a single positive product test, often carries these cases. By the time people get sick and call a doctor, the salad is eaten and the lot is out of date. Investigators then lean on detailed interviews, receipts, and shipping records.
That is how they close in on one supplier and one ingredient. The Food and Drug Administration described that exact process here, with lines of evidence meeting at Taylor Farms de Mexico.
What Authorities And Businesses Did, And What Consumers Should Do
The Food and Drug Administration opened an inspection at Taylor Farms de Mexico’s facility in Guanajuato, Mexico, and collected samples to probe sanitary controls.
The agency also coordinated with state partners and the Centers for Disease Control and Prevention on new cases and exposure histories.
Meanwhile, Taylor Farms de Mexico pulled the implicated lettuce, and distributors followed with removals. Restaurant chains that were supplied took action to switch sources or pull lettuce tied to the recall.

Consumers who bought recalled salad bags should check freezers and fridges, though federal updates say the printed dates have now lapsed. People who ate at restaurants on the exposure list and have lasting diarrhea, weight loss, or fatigue should ask a doctor for Cyclospora testing.
Treatment is available. Cleaning kitchen tools and surfaces with hot, soapy water helps. For future shopping, rinse produce under running water and dry with a clean cloth. Washing does not remove all risk but it can lower it.
