Multistate Outbreak of Hepatitis A Associated with Frozen Strawberries
Abstract
A multistate outbreak of hepatitis A was traced to frozen strawberries processed at a single plant. Among 827 students and 60 teachers at an elementary school in Georgia during a 2-week period, 15 developed hepatitis A. Three months later, among 174 residents and 467 staff in an institution for the developmentally disabled in Montana during a 3-week period, 13 developed hepatitis A. Primary attack rates were 10% in the school and 8% in the institution. Cohort analysis in the school implicated consumption of strawberry shortcake in hepatitis A virus (HAV) infection (relative risk, 7.6; 95% confidence interval, 1.04-55.6). In the institution, such analysis implicated desserts and uncooked strawberries as the most biologically plausible vehicle of HAV transmission. Molecular analysis of HAV from patients in the two outbreaks revealed that the viral genomes were genetically identical and distinct from other known US strains. Contamination of food products before retail distribution is rare but should be considered in investigating common-source outbreaks of hepatitis A.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
