Taylor Farms lettuce sample that tested positive for cyclospora was a false positive, FDA says - CBS News

A sample of lettuce from Taylor Farms that had tested positive for cyclospora was a false positive, the Food and Drug Administration said Sunday. But the FDA said Monday that its investigation and data "continue to converge on shredded iceberg lettuce from Taylor Farms locations in central Mexico." In the statement announcing the false positive, the FDA said that as of Sunday it had not found any "confirmed positive sample results for product testing for Cyclospora." In a subsequent statement Monday, it said, "To clarify, this false-positive lab sample DOES NOT change the basis for FDA's ongoing outbreak investigation or the overwhelming epidemiological data supporting the current voluntary recall by Taylor Farms." Taylor Farms on Friday said it was "voluntarily removing" iceberg lettuce sourced from central Mexico after the lettuce had been linked to one of the largest outbreaks of cyclosporiasis in the U.S. in recent years.
