Attributing the Source of Foodborne Salmonellosis in NSW

In 2010 there were an estimated 39,600 Australian cases of foodborne gastroenteritis caused by Salmonella. Livestock (particularly chickens, pigs, cows and sheep) and wildlife are reservoirs of the pathogen, but the proportional contribution of each source to human cases is unknown in NSW. We propose using existing Salmonella surveillance data from human cases and animal reservoirs to determine the burden of human disease attributable to each foodborne source in NSW. This work will adapt methods we have used previously for the source attribution of salmonellosis in South Australia and Queensland.
