Epidemiologic Data

As of March 30, 2023, 12 people infected with the outbreak strain of Salmonella have been reported from 11 states (see map). Illnesses started on dates ranging from December 6, 2022, to February 13, 2023 (see timeline).

Public health officials collect many different types of information from sick people, including their age, race, ethnicity, other demographics, and the foods they ate in the week before they got sick. This information provides clues to help investigators identify the source of the outbreak.

Sick people range in age from 12 to 81 years, with a median age of 64, and 92% are female. Of 10 people with race or ethnicity information available, 8 are White, 2 are Asian, and no one reported Hispanic ethnicity. Of 12 people with information available, 3 have been hospitalized. No deaths have been reported.

State and local public health officials are interviewing people about the foods they ate in the week before they got sick. Of the 7 people interviewed, 6 (86%) reported eating raw dough or batter. Flour was the only common ingredient in the raw dough or batter people reported eating. Investigators are working to identify a specific brand of raw flour that is linked to illnesses.
