Confusion Swirls on Source of Diarrhea Outbreak, but It's Still Taylor Farms
Federal officials reaffirmed that Taylor Farms iceberg lettuce is the likely source of a Cyclospora outbreak causing thousands of cases, despite a false positive FDA test. The recall remains vague, and a delayed traceability rule has drawn political scrutiny.
The U.S. Food and Drug Administration on Monday reiterated that iceberg lettuce from Taylor Farms appears to be the source of a Cyclospora outbreak, the microscopic parasite behind a surge in explosive diarrhea cases. The statement aimed to clear up confusion from the weekend after the FDA rescinded a false positive test result.
Traceback investigations focusing on Taco Bell restaurants found that shredded iceberg lettuce from Central Mexico, supplied by Taylor Farms, was linked to illnesses. On Friday, the FDA and CDC publicly identified Taylor Farms, which issued a voluntary recall for all its iceberg lettuce sourced from Central Mexico between June 29 and July 16. Initially, contamination was thought limited to Taco Bell locations in five states.
On Saturday, the FDA announced a positive Cyclospora test on a Taylor Farms sample, but on Sunday it deleted the information, calling it a false positive. Taylor Farms celebrated the reversal, claiming the FDA apologized. The FDA denied any apology and stressed that the false result does not change the epidemiological data supporting the recall.
The recall list is vague—Taylor Farms has not disclosed distributor or customer details. However, Walmart's Marketside lettuce, Sysco, US Foods, and Jack in the Box have been affected. The company said the potentially contaminated lettuce reached 27 states, but CDC data shows cases in at least 34 states. The case count is in the thousands, exceeding the usual annual range of 2,000 to 5,000. In Michigan alone, there are 6,571 cases and 102 hospitalizations as of July 21.
Complicating matters, the FDA does not currently require producers to provide customer lists. A new FDA Food Traceability Rule was delayed from January 2026 to July 2028 under the Trump administration. Five days after the delay, Taylor Fresh Foods (Taylor Farms) donated $1 million to a Trump-supporting super PAC. The Department of Health and Human Services called the speculation "FAKE NEWS." Taylor Farms did not respond to a comment request.
