The FDA says Taylor Farms lettuce remains a key part of its Cyclospora outbreak investigation, even after one lettuce sample that initially appeared to test positive was later determined to be a false positive. The agency said it had not identified any confirmed positive product test results as of Sunday.
According to the agency, the false positive does not end the broader review. Federal officials said their investigation and data analysis are still centered on Taylor Farms lettuce as they work to better understand the source of the cyclosporiasis outbreak.
The update highlights the difference between an early test result and a confirmed finding. While the product sample did not ultimately verify as positive for Cyclospora, the FDA indicated that other evidence gathered during the investigation continues to keep Taylor Farms lettuce under scrutiny.
Cyclospora investigations can be complex because health officials often rely on multiple forms of information, including testing and outbreak data, to trace a possible source. For now, the FDA says the inquiry is ongoing, with Taylor Farms lettuce still at the center of the review despite the false positive result.
