The FDA has concluded its investigation into the largest recorded multistate cyclosporiasis outbreak in U.S. history, which was linked to recalled shredded iceberg lettuce sourced from central Mexico by Taylor Farms.
Investigators detected Cyclospora in two environmental samples: one from a wastewater tank at the Taylor Farms de Mexico processing facility and another from a drainage ditch at an iceberg lettuce grower.
The grower is no longer part of Taylor Farms’ supplier program.
The outbreak sickened 12,883 people across 21 states, resulting in 570 hospitalizations and two deaths.
For context, the U.S. reported nearly 20,000 domestically acquired Cyclospora cases overall during the 2026 season, so the Taylor Farms-linked outbreak accounted for a large share of the total.
The CDC declared the outbreak over on September 11.
FDA said the findings provide strong evidence supporting the link to the recalled lettuce, although investigators could not definitively determine how the lettuce became contaminated.
