The lettuce cyclospora outbreak has reached 15 states. Will it top 20 before Aug 21?

The multistate Cyclospora outbreak linked to Taylor Farms de Mexico iceberg lettuce grew through August 2026 but had not reached 20 states by the question's August 21 deadline. The Washington Post reported the outbreak had expanded to 15 states as of August 4, and by the CDC's investigation update referencing data through August 13, the count stood at 17 states, with roughly 10,930 illnesses, 454 hospitalizations and two deaths reported in Michigan. Taylor Farms had recalled all iceberg lettuce sourced from central Mexico on July 17 after epidemiologic and traceback data identified the lettuce as the contamination source. Many of the illnesses counted in later updates had onset dates preceding the recall, as case interviews and lab confirmations lagged behind actual infections. The outbreak was described by health officials as the largest known Cyclospora outbreak on record, but its state count plateaued in the high teens rather than crossing 20 within the question's window. The community unanimously predicted the outbreak would top 20 states, but the actual state count stayed below that threshold, so the community's forecast did not match the outcome.
