The FDA reported Oct. 2 that it detected Cyclospora in wastewater from Taylor Farms de Mexico’s lettuce processing facility and in a drainage ditch at a farm identified in its investigation. The findings add environmental evidence to the link between recalled Taylor Farms iceberg lettuce and a summer outbreak that sickened 12,883 people, but the FDA says it cannot yet determine how contamination occurred.

The Food and Drug Administration detected Cyclospora in wastewater at a Taylor Farms lettuce processing facility in Central Mexico and in a drainage ditch at a farm identified in its investigation, adding environmental evidence to the link between the company’s iceberg lettuce and a summer outbreak that sickened 12,883 people. The FDA said Oct. 2 that the findings show the parasite was present where lettuce was grown and processed, but do not establish how contamination occurred.

The FDA said two environmental samples collected during inspections in Mexico tested positive for Cyclospora. One came from a tank holding outgoing wastewater at the Taylor Farms de Mexico processing facility; the other came from a drainage ditch at an iceberg lettuce grower identified through the agency’s traceback investigation. Investigators collected samples of water, soil, sediment and lettuce at multiple growers and the processing facility, working with Mexican officials.

The outbreak was linked to recalled shredded iceberg lettuce distributed by Taylor Fresh Foods. The CDC counted 12,883 illnesses, 570 hospitalizations and two deaths. It reported on Sept. 11 that the outbreak had ended. The FDA said the environmental findings add to epidemiological evidence and traceback results connecting the outbreak to lettuce from the operation.

The FDA said genotyping of both positive samples is complete, but it is still analyzing how their results relate to genotyping of samples from outbreak patients. A Taylor Fresh Foods spokesperson told ABC News that the Central Mexico facility remains closed while the company works with its research team on enhanced safety protocols. The spokesperson also said the independent grower where the positive sample was found is no longer in the company’s supplier program.

Environmental Evidence in the Outbreak

The positive results matter because they document Cyclospora in the environment at locations connected to the lettuce supply chain under investigation. That evidence supports the FDA’s broader assessment linking the recalled lettuce to the outbreak, while falling short of identifying the precise route by which food may have been contaminated.

For consumers, the outbreak’s scale—12,883 illnesses and 570 hospitalizations—shows the potential public-health impact of contamination involving widely distributed produce. The CDC has said the outbreak ended, but the investigation’s findings may inform how regulators and the company review sanitation, water management and supplier controls. The source material does not establish which specific corrective measures will be adopted or when the facility could reopen.

How Investigators Traced the Lettuce

Initial links between illnesses and Taylor Farms lettuce emerged in July, after people who ate Taco Bell menu items containing the lettuce became ill. Taco Bell had sourced the lettuce from Taylor Farms, according to the report. The FDA’s traceback work identified several farms and a processing facility in Mexico that supplied lettuce later recalled and distributed by Taylor Fresh Foods.

As part of its investigation, the FDA conducted inspections and collected samples at multiple iceberg lettuce growers and at the processing site, coordinating with Mexican officials. The Oct. 2 findings followed the CDC’s Sept. 11 report that the outbreak had ended. The new environmental results add information to the investigation, but they do not by themselves show that either positive sample contaminated lettuce eaten by outbreak patients.

“There is currently not enough evidence to conclusively determine how contamination occurred in the outbreak.”

The Contamination Route Remains Unknown

The FDA said it does not yet have enough evidence to determine how contamination occurred. Although genotyping of the two environmental samples is complete, the agency is still analyzing how those results compare with genotyping from outbreak patients. The source material does not report a completed match between the environmental samples and patient specimens.

It also remains unclear whether either positive sample directly contaminated lettuce, when the parasite entered the relevant environments, or what specific conditions allowed it to spread. The FDA’s findings support a link between the outbreak and recalled lettuce from the operation; they do not establish a complete causal chain from either sample to individual illnesses.

Genotyping and Facility Status

The FDA’s next stated step is to continue comparing the genotyping results from the two positive environmental samples with those from outbreak patients. That analysis may help clarify whether the samples are related to the outbreak, though the agency has not provided a completion date in the report.

The Taylor Farms de Mexico facility remains closed, according to a company spokesperson quoted by ABC News, while the company works on enhanced safety protocols. The source material does not give a reopening timeline or describe the protocols in detail. The CDC has reported the outbreak ended; further updates from the FDA or company could clarify the investigation’s conclusions and any operational changes.

Key Questions

Where did the FDA find Cyclospora?

The FDA reported positive results from outgoing wastewater held in a tank at Taylor Farms de Mexico’s processing facility and from a drainage ditch at an iceberg lettuce grower identified in its traceback investigation.

How large was the summer outbreak?

The CDC counted 12,883 illnesses, 570 hospitalizations and two deaths. It reported on Sept. 11 that the outbreak had ended.

Has the FDA determined how the lettuce became contaminated?

No. The FDA said there is not enough evidence to conclusively determine how contamination occurred. It is continuing to analyze how the environmental sample genotyping relates to results from outbreak patients.

Is the Taylor Farms facility open?

A Taylor Fresh Foods spokesperson told ABC News that the Central Mexico facility remains closed while the company works on enhanced safety protocols. No reopening date was provided in the source material.
