Cyclospora Outbreak Map: State-by-State
Last updated automatically each day — darkblue = no reported cases, hot red = primary outbreak cluster
Methodology: CDC/FDA do not publish a live public
per-state case-count API for this outbreak, so this map combines a CDC outbreak-map data
export (the 9-state Taco Bell/Taylor Farms de Mexico lettuce cluster, as of July 23, 2026),
a CDC-derived third-party tracker (GenomicEpi.com, July 18, 2026), and state health department
reporting where published. Two different figures exist per state and are kept
separate rather than merged: a “multistate cluster” count (cases specifically tied to
the Taco Bell lettuce investigation) and a “statewide total” (that state’s full reported case
count, which can be much larger — e.g. Michigan’s own outbreak, 9,253 cases as of July 27 per
MDHHS, is far bigger than its 931-case cluster subset). As of July 22, 2026, CDC/press reported
cases in 41 states total; states confirmed to have cases but without a published exact count
are shaded “reported, count TBD.” Figures will be corrected as CDC/FDA/state health departments
update their pages.
