Skip to content Trends Counts of records , not of illnesses in the population. A rise can mean more illness, more testing, or a source publishing a backlog. Recent months are always incomplete because outbreak reporting lags investigation by months to years.

Multistate records are counted once, under their primary state, so this is not a per-state incidence rate and is not population-adjusted.
Foodborne Watch aggregates published records from CDC, FDA and state health agencies. Records are shown as their source states them; a record is never described as confirmed unless the source says so. See methodology for coverage, caveats and update timing.
