Cyclospora Cases Top 4,000 as Mexico Rejects FDA Link to Taylor Farms Lettuce

Summary
More than 4,000 lab-confirmed Cyclospora cases had been recorded across 41 U.S. states by July 21, while officials estimate the true toll exceeds 10,000.
Mexico's health minister rejected the FDA's claim that the outbreak traces to Taylor Farms lettuce grown in Guanajuato, even as Taylor Farms kept a voluntary recall in place after traceback data pointed to shredded iceberg lettuce from central Mexico.
RFK Jr. said the outbreak was "under control" and defended cuts to FoodNet, arguing reduced surveillance was redundant despite criticism that weaker staffing and monitoring worsened the spread.
FDA said a reported false-positive lettuce test does not alter its investigation because cyclospora outbreaks are usually built on epidemiological traceback, not product samples that are often gone by the time cases are identified.
Cyclospora is harder to pin down than E. coli or listeria because it cannot be cultured easily and lacks the same whole-genome sequencing tools, forcing investigators to rely on slower genotyping, patient interviews and supply-chain records.
