U.S. health officials admitted on July 20, 2026 that lettuce from Taylor Farms tested positive for cyclospora parasite but later found the lab findings mistaken. Testing errors at the FDA facility, not from anything wrong with the food itself. The confusion left shoppers in the dark about a wider Cyclospora hitting a number of U.S. states. Reports climbed while authorities tried for the true source. Taylor Farms lettuce has been cleared. The hunt for the actual cause continues.
