The Food and Drug Administration said a test sample of Taylor Farms lettuce that initially pointed to cyclospora was a false positive, according to TODAY. The update leaves investigators without a confirmed product link in an outbreak that TODAY reported has sickened thousands of people across the country.
The FDA said no products have tested positive for the disease, according to TODAY’s report. The agency said it is continuing to investigate the outbreak.
The development adds uncertainty to the search for the source of the illnesses. TODAY reported that the Taylor Farms lettuce sample had appeared to test positive before the FDA determined the result was not valid.
NBC’s Anne Thompson reported the update for TODAY on July 20, 2026. The report said the FDA has not identified any product that has tested positive for cyclospora.
