FDA Retracted Cyclospora Test on Taylor Farms Lettuce but Still Names Mexican Facility as Likely Source

Over three consecutive days, the FDA reported a positive Cyclospora test on Taylor Farms lettuce from Mexico, retracted it as a false positive, then continued naming Taylor Farms' Mexican facilities as the likely outbreak source — without a confirmed product test. Taylor Farms stated "at this moment, FDA has not identified a single positive product test result for Cyclospora." The FDA relies on supply-chain traceback, not lab confirmation, for source attribution.
