FDA says Taylor Farms lettuce cyclospora test produced a false positive

foodJul 20, 202616313,545

On July 19 the U.S. Food and Drug Administration said laboratory experts re-checked a previously reported cyclospora-positive shredded iceberg lettuce sample from Taylor Farms and concluded the result was a false positive. The FDA said there were no confirmed positive sample results for cyclospora as of July 19 and that officials had earlier reported the single positive test on July 18. The agency notified Taylor Farms and said it is continuing to work with the company to ensure product implicated in the outbreak has been removed from the market. Taylor Farms had told the FDA the specific product was not part of its current recall. The cyclospora outbreak has been linked by public health officials to shredded iceberg lettuce served at Yum Brands Taco Bell restaurants in Indiana, Kentucky, Michigan, Ohio and West Virginia and has resulted in about 100 hospitalizations and no deaths, according to the CDC. Reuters and FDA reporting say the lettuce was produced as 5-pound bags at Taylor Farms’ facility in Guanajuato, Mexico and shipments began June 29 with expiration dates through August 3. The FDA’s re-check narrows confirmed laboratory evidence against Taylor Farms but the agency is maintaining its product-removal and investigation steps.

This is what I have verified about Taylor Farms and this administration: 1. Bruce Taylor met with Trump on 07/16/26. 3. The FDA reversed its previous warning about Taylor Farms on 07/19/26. 4. Taylor Farms gave $1 million to Trump's PAC. I don't know when, but that's what got Taylor the meeting.

This is a *fantastic* video that explains exactly WTF is going on with Taylor Farms and how tracing works TLDR: - they are responsible - the false positive was only on one of several samples - it’s difficult to test parasites - there may still be other sources - Taylor Farms is being shady AF

1/ Over the weekend, the FDA announced that a lettuce sample from Taylor Farms tested positive for Cyclospora. Within 24 hours, the FDA backtracked, calling the result a false positive. Taylor Farms quickly deleted its own posts about its bagged lettuce and boasted the FDA had apologized to them.

Important context for the diarrhea outbreak is that usually most Cyclospora outbreaks do not get traced back to a specific source. They are difficult to trace due to long incubation period, short shelf life of produce, it's hard to grow the parasite in the lab, and its genome is hard to sequence.

Once again… Don’t trust a damn thing this administration says. Believe your lying eyes when you see thousands of cases of sick people nationwide. www.reuters.com/business/hea...
