The FDA has closed its probe into a massive Cyclospora outbreak, citing strong evidence that linked more than 12,800 infections to recalled iceberg lettuce from Taylor Farms de Mexico.
Federal health officials said Friday they finished investigating the Cyclospora outbreak tied to iceberg lettuce sourced from Mexico and sold across the United States.
Fox Business reported the agency found “strong” evidence connecting the infections to recalled products from Taylor Farms de Mexico. The outbreak sickened more than 12,800 people in 21 states, put hundreds in hospitals, and was linked to two deaths in Michigan.
Both people who died had significant underlying health conditions, health officials said. The Centers for Disease Control and Prevention had already declared the outbreak over on Sept. 11. The FDA’s wrap-up now puts a firmer stamp on where the contamination trail led.
In July, Taylor Farms de Mexico announced it was voluntarily pulling all iceberg lettuce sourced from central Mexico off U.S. shelves. Parent company Taylor Fresh Foods had distributed the shredded lettuce tied to the cases.
After the recall, the FDA started onsite inspections in Mexico. Traceback work identified multiple farms and a processing facility there that supplied the recalled product.
Two environmental samples tested positive for Cyclospora. One came from a tank holding outgoing wastewater at the company’s processing facility. The other came from a drainage ditch at an iceberg lettuce farm.
The FDA said it could not pin down exactly how the contamination happened. Still, the agency pointed to the samples, the epidemiology, and the traceback as a clear package.
The agency put it this way:
"While there is currently not enough evidence to conclusively determine how contamination occurred in this outbreak, the positive samples show that Cyclospora was present in the environment where lettuce was grown and processed,"
And it added:
"This adds to the strong epidemiological data and traceback convergence supporting the link between this outbreak and recalled shredded iceberg lettuce from Taylor Farms de Mexico,"
Officials also said they are confident all recalled iceberg lettuce linked to the outbreak is out of the U.S. market.
A spokesperson for Taylor Fresh Foods answered the findings in a statement to Reuters. The company removed the independent grower tied to one positive sample from its supplier program.
The spokesperson said:
"The independent grower where a positive sample was found is no longer part of our supplier program. The sample FDA referenced came from discharged waste and sewer water outside of our processing facility,"
The company also leaned on the same gap the FDA acknowledged:
"As FDA noted in its report, there is currently not enough evidence to conclusively determine how contamination occurred or how results for these samples relate to ongoing genotyping of clinical specimens,"
That leaves a familiar pattern in large produce outbreaks. Regulators show a strong link to a product and a place. The precise path of contamination stays murky. Shoppers and hospitals live with the results either way.
Cyclospora is a single-celled parasite. The CDC says it can cause stomach cramps, nausea, fatigue, weight loss, and other problems. Some infected people show no symptoms at all.
More than 12,800 confirmed cases across 21 states is not a minor spike. Hundreds of hospitalizations and two linked deaths in Michigan make the scale plain. The documents described the event as one of the larger foodborne illness episodes in recent U.S. history.
Iceberg lettuce from central Mexico moved through farms, a processing facility, and into American distribution. Packages of Taylor Farms greens still appeared on store shelves during the recall window, including at a Safeway in California. Fields near Taylor Farms operations in Doctor Mora, Guanajuato state, Mexico, were photographed after the company announced a temporary closure.
Marzetti Company President and CEO Dave Ciesinski discussed how the outbreak hit the salad mix and dressing business, along with inflation pressures, in a Fox Business video segment. The financial squeeze on the salad side of the industry was part of the public conversation once the recall landed.
The traceback did not stop at a single farm gate. It ran to multiple farms and a processing site in Mexico that fed product into the Taylor Fresh Foods distribution chain. Positive samples turned up in wastewater and a farm drainage ditch. Those details matter because they show the parasite was present in the growing and processing environment, even if the exact entry point remains unproven.
Taylor Fresh Foods moved the implicated grower out of its program and noted the wastewater sample sat outside the processing facility. The FDA still treated the full set of data, epidemiology, traceback, and environmental positives, as strong support for the link to the recalled shredded iceberg lettuce.
For consumers, the practical bottom line is simpler. A widely distributed salad staple carried a parasite that made thousands sick. The product came from central Mexico. The recall was voluntary. The investigation closed after the CDC had already called the outbreak over. And the agency still cannot say with certainty how the lettuce got contaminated in the first place.
Food safety rules exist so American families do not have to run that risk with every bag of greens. When more than 12,000 people get sick and hospitals fill up, the supply chain that put that lettuce on U.S. shelves failed a basic test of protection.
Imported produce can move fast and far. When contamination follows it across the border and into 21 states, the cost lands on patients, employers, and an industry already fighting inflation. Accountability has to reach the farms, the processors, and the systems that green-light that product for American stores.
Shoppers should not need a federal investigation to trust the lettuce in their fridge. When foreign-sourced greens sicken thousands, the failure is not abstract, it is on the plate.
