A recent analysis of a Canadian foodborne salmonellosis outbreak investigation has highlighted the importance of considering possible aerosolization of bacteria from drainage systems in restaurants as a risk factor for foodborne illness outbreaks.
In May 2020, the Public Health Department of the Integrated University Health and Social Services Center of the Capitol of Quebec (DSPu) received a report from the Quebec Public Health Laboratory about a cluster of Salmonellainfections. The epidemiological investigation identified a total of 67 cases between January 1, 2020 and August 13, 2021, 66 percent of which were directly linked to a local restaurant. The Salmonella strains from most of the cases were found to be identical by whole genome sequencing (WGS).
