Canadian health officials published a report about seven cases of typhoid fever over four years (from 2018 to 2022) that were linked to an asymptomatic chronic S. Typhi carrier who worked irregularly as a food handler at various locations of a grocery store chain. Transmission occurred through food handling, shared workspaces and social and household networks. Although the outbreak was relatively small, six of seven cases were hospitalized with significant morbidity.
