Shredded Lettuce Identified as Potential Source in Cyclosporiasis Outbreak
Investigators have identified shredded iceberg lettuce supplied to Taco Bell restaurants by Taylor Farms as a potential source of contamination in an ongoing outbreak of the intestinal illness cyclosporiasis, according to individuals familiar with the investigation. The outbreak, which has sickened thousands across the United States during the summer of 2026, has been linked to cases in Indiana, Kentucky, Michigan, Ohio, and West Virginia.

Investigation Into Taco Bell and Supply Chain
The Food and Drug Administration (FDA) is leading the investigation into the outbreak, which is caused by the parasite Cyclospora. While the number of cases is significantly higher than typical summer figures, much of the activity is centered in Michigan. According to sources familiar with the FDA’s work, investigators identified a single supplier of iceberg lettuce from Mexico that was provided to the specific Taco Bell locations where affected individuals consumed food.
Taco Bell has not confirmed whether it currently uses Taylor Farms as a supplier. In a statement provided on July 15, the company emphasized that public health officials have not confirmed a link to any specific ingredient, restaurant, supplier, or retailer. As a precautionary measure, the chain has voluntarily and temporarily removed limited ingredients at select restaurants while authorities continue their broader review.
Status of Taylor Farms
Taylor Farms, a distributor of fresh produce and salad kits, has been the subject of significant online discussion regarding the outbreak. While social media users have pointed to the company’s history—including a 2013 cyclosporiasis outbreak in Iowa and Nebraska—public health officials have not made any official announcements linking the company to the 2026 cases. As of July 14, Taylor Farms’ internal records indicated there were no active product recalls for the company’s goods. The company did not respond to repeated inquiries regarding the alleged investigation.
Understanding the Illness and Response
Cyclosporiasis is an intestinal illness caused by the Cyclospora parasite, which is typically transmitted through the consumption of food or water contaminated with feces. Symptoms of the illness include what has been described as “explosive diarrhea.”

The following table summarizes the status of key entities involved in the ongoing reports:
| Entity | Status/Action |
|---|---|
| FDA | Leading the investigation into the source of the outbreak. |
| Taco Bell | Voluntarily removed limited ingredients; states no link to specific suppliers confirmed. |
| Taylor Farms | Identified by anonymous sources as a potential supplier of implicated lettuce; no active recalls reported. |
Context and Limitations of Reporting
The identification of Taylor Farms as a potential source stems from reports citing anonymous sources. Journalists have noted that these sources are considered authoritative, yet official government agencies, including the FDA and the Centers for Disease Control and Prevention (CDC), have not provided confirmation regarding the investigation into the supplier.
The investigation remains active, and public health authorities have yet to issue a definitive statement connecting any single company to the thousands of illnesses reported. The fast-food chain’s current relationship with the produce supplier remains unverified, as Taco Bell has not answered questions regarding its 2026 supply chain, despite historical reports from 2006 indicating the company had switched to Taylor Farms following an E. coli outbreak.
Update (July 17, 2026)
According to washingtonpost.com, the CDC and FDA officially confirmed on July 16 that the multistate cyclosporiasis outbreak is linked to shredded iceberg lettuce served at Taco Bell restaurants in Indiana, Kentucky, Michigan, Ohio, and West Virginia. Federal officials urged consumers not to eat shredded iceberg lettuce from Taco Bell in those states. The investigation has identified more than 1,644 sick people who reported eating at Taco Bell locations in the five states.
Taco Bell announced that the affected ingredient from its supplier is being indefinitely removed from its supply chain nationwide and will be replaced within 24 hours in select states. While the agencies did not name the supplier, individuals familiar with the inquiry confirmed it is Taylor Farms. As of Thursday, more than 4,300 cases have been reported in Michigan, with at least 100 people hospitalized.
