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.
