Objective: To investigate the effects of foodborne bacteria on outbreaks, and outbreak-associated illnesses and hospitalizations in the United States (U.S.).
Methods: Aggregate data was obtained from the CDC WONDER (Wide-ranging Online Data for Epidemiologic Research) database showing the number of foodborne outbreaks (1993-2017), and outbreak-associated illnesses (1993-2017) and hospitalizations (1998-2017) caused by foodborne bacteria. Species of bacteria were grouped into 13 genera and 1 other. An Analysis of variance (ANOVA) test was used to compare the mean outbreaks, and outbreak-associated illnesses and hospitalizations for each of the years using the data by species for each year. Results: There was no statistically significant difference in the mean outbreaks (p = 0.544), outbreak-associated illnesses (p = 0.462) and hospitalizations (p = 0.949) caused by foodborne bacteria.
Conclusion: Foodborne infections are generally self-limiting and may explain the lack of significant change in the mean bacterial foodborne outbreaks, illnesses, and hospitalizations in the U.S.
