A major summer food-safety investigation is again putting imported leafy greens under national scrutiny as federal officials track one of the largest Cyclospora outbreaks in recent years. Taylor Farms, the Salinas-based produce company at the center of the case, has continued to reject responsibility even as the FDA and CDC say their investigation points to recalled iceberg lettuce from the company’s central Mexico supply chain. The dispute comes as regulators expand the outbreak and continue testing, traceback, and case interviews.
Federal investigators expand the outbreak as Taylor Farms contests the link
The FDA said on August 5 that 6,358 laboratory-confirmed illnesses in 15 states are now tied to the Cyclospora outbreak linked to iceberg lettuce, with 278 hospitalizations and two reported deaths in Michigan. According to the agency’s outbreak advisory, the case total rose sharply after CDC added people who reported exposure to Taco Bell or to recalled Taylor Farms de Mexico iceberg lettuce. Illness onsets in the outbreak ran from June 22 through July 31, 2026, and the FDA said more confirmed cases could still be added because Cyclospora investigations can take up to six weeks.
Taylor Farms de Mexico initiated its voluntary recall on July 17, 2026, removing all iceberg lettuce sourced from central Mexico from the U.S. market, according to the company’s FDA-posted recall notice. The recall covered foodservice product distributed from June 29 through July 16 and also included Walmart Marketside products identified by the FDA as 12-ounce and 24-ounce Iceberg Salad and 8-ounce and 16-ounce Shredded Lettuce with best-by dates from July 18 through August 3, 2026. The FDA has continued to tell consumers, retailers, and restaurants not to eat or use the recalled lettuce and to discard it or return it for a refund.
Taylor Farms has said its own internal testing did not find Cyclospora contamination, a position echoed in recent public statements cited by Food Safety News. Federal regulators, however, said the investigation continues to converge on shredded iceberg lettuce from Taylor Farms de Mexico growers in central Mexico. The FDA also noted on July 19 that an earlier border sample first reported as positive was re-reviewed and determined to be a false positive, while adding that the revised lab finding did not alter the epidemiological basis for the recall or the broader outbreak investigation.
The confirmed footprint reaches 15 illness states and far more distribution states
For consumers and food businesses in the United States, the scope of the recall is broader than the 15 states currently reporting confirmed outbreak illnesses. The FDA said illnesses tied to the outbreak have been confirmed in Arkansas, Iowa, Illinois, Indiana, Kansas, Kentucky, Michigan, Missouri, Nebraska, New Hampshire, North Carolina, Ohio, Oklahoma, Pennsylvania, and West Virginia. Those are the states where officials have linked laboratory-confirmed cases to this outbreak as of the August 5 federal update.
The recalled product, however, was distributed more widely. According to both the FDA outbreak advisory and Taylor Fresh Foods’ recall notice, recalled foodservice iceberg lettuce moved through Alabama, Arkansas, Connecticut, Florida, Georgia, Iowa, Illinois, Indiana, Kansas, Kentucky, Louisiana, Massachusetts, Maryland, Michigan, Missouri, Mississippi, North Carolina, New Hampshire, New Jersey, New York, Ohio, Oklahoma, Pennsylvania, South Carolina, Tennessee, Texas, Virginia, Wisconsin, and West Virginia. FDA also said customer information shows recalled product was sold in Mexico.
What remains unconfirmed is the full retail and restaurant-by-restaurant list of affected sites. The FDA has said Taco Bell locations that received the recalled lettuce include at least stores in Arkansas, Iowa, Illinois, Indiana, Kansas, Kentucky, Michigan, Missouri, Nebraska, Ohio, Oklahoma, Pennsylvania, and West Virginia, with additional states possible as the investigation continues. The company has not released a comprehensive public list of every restaurant or store location that handled the recalled lettuce.
Regulators point to traceback and past findings as the broader context
The current dispute is unfolding against a long backdrop of Cyclospora problems in fresh produce, especially where traceback depends more on illness interviews and supply-chain records than on a positive test from leftover product. The FDA said its investigators traced the current outbreak to central Mexico after identifying convergence on a single supplier in the Taco Bell supply chain. The agency has also said product testing can be limited in these cases because contaminated produce may already be eaten or no longer within shelf life by the time an outbreak is recognized.
The historical context has added scrutiny. An FDA environmental assessment of a 2013 Cyclospora outbreak linked salad mix supplied by Taylor Farms de Mexico to illnesses in Iowa and Nebraska and identified the company’s Doctor Mora, Guanajuato, processing facility as part of that investigation. The assessment said the suspect mix included iceberg lettuce and other produce, and Food Safety News reported this week that the same central Mexico operation is implicated again in the 2026 outbreak.
For customers, the immediate takeaway remains unchanged: recalled Taylor Farms de Mexico iceberg lettuce should not be eaten and should be discarded or returned where purchased, with exposed surfaces cleaned and sanitized, according to the FDA. Taco Bell said it stopped using lettuce from Taylor Farms de Mexico on July 17, and federal officials said more information will be released as the investigation develops. As of August 5, the outbreak remained active and under joint review by the FDA, CDC, and state partners.
