The US Food and Drug Administration said Sunday that lab experts re-checked a lettuce sample from Taylor Farms and concluded the finding was a false positive. As of Sunday, no confirmed positive sample results for cyclospora existed, the FDA added.
The agency had reported Saturday that a sample of shredded iceberg lettuce supplied by Taylor Farms tested positive for the parasite. Cyclospora has sickened thousands of people in the US.
The FDA said it notified Taylor Farms and continues working with the firm to ensure product implicated in the outbreak has been removed from the market. Taylor Farms earlier confirmed that the product was not part of its current recall, according to the FDA. The company was not immediately available for comment.
Cyclosporiasis has been linked to shredded iceberg lettuce served at Yum Brands' Taco Bell restaurants in Indiana, Kentucky, Michigan, Ohio and West Virginia. The outbreak has resulted in around 100 hospitalizations and no deaths, according to the Centers for Disease Control and Prevention.
The lettuce, which the FDA said late Thursday came from Mexico, was produced as 5-pound bags at Taylor Farms' facility in Guanajuato, Mexico, a source told Reuters.
