July 19 (Reuters) - The U.S. Food and Drug Administration said on Sunday that laboratory experts ​re-checked lettuce sample results from Taylor Farms in an ‌investigation into an outbreak of the cyclospora parasite and concluded the finding should be considered a false positive. As of Sunday, there were no confirmed ​positive sample results for cyclospora, the FDA added.

The FDA on ​Saturday had said that a sample of shredded iceberg lettuce ⁠supplied by Taylor Farms tested positive for the parasitic illness ​that has sickened thousands of people in the U.S.

A spokesperson ​for Taylor Fresh Foods told Reuters that the company was informed the FDA made a mistake.
