Cyclospora outbreak: FDA says it made a 'false positive.' Taylor Farms lettuce products are still being recalled - Fast Company

There is a new update regarding the Cyclospora outbreak that has affected multiple states across the nation, causing explosive diarrhea in hundreds of individuals.

The update includes a recall of select lettuce products made by a major food manufacturer, but additional comments from the U.S. Food and Drug Administration (FDA) are likely to cause confusion. Here’s the latest and what you need to know.

What’s happened?

On Friday, July 17, Taylor Fresh Foods, which sells pre-made salad products under the Taylor Farms brand, announced a voluntary recall of numerous lettuce products sold to food companies and at retailers.

Lettuce within the products was feared to have been sourced from a lot in central Mexico that could be contaminated with Cyclospora. The FDA published this recall notice a day later, on Saturday, July 18.

However, on Sunday, July 19, the FDA published a Cyclospora Investigation update that said the agency erred in its testing of lettuce under investigation, and that the product tested was actually a false positive.

“Due to the complexity in detection of Cyclospora, FDA laboratory experts re-reviewed the sample results and have concluded that the finding does not represent true amplification and should be considered a false positive,” the agency clarified.

On July 19, Taylor Farms also posted a statement on its website saying that the FDA had apologized to the company.
