The Epidemiology of Salmonella enterica Outbreaks in Australia, 2001–2016

Abstract

Salmonella enterica is an important cause of foodborne illness in Australia, regularly causing high-profile outbreaks involving commercially-available foods. We used the national register of foodborne outbreaks to review the transmission pathways, settings, serotypes, and food vehicles of Salmonella outbreaks in Australia between 2001 and 2016.
