Listeriosis is a foodborne disease associated with significant mortality. This study attempts to identify risk factors for sporadic listeriosis in Australia. Information on underlying illnesses was obtained from cases' treating doctors and other risk factors were elicited from the patient or a surrogate. We attempted to recruit two controls per case matched on age and primary underlying immune condition. Between November 2001 and December 2004 we recruited 136 cases and 97 controls. Of perinatal cases, living in a household where a language other than English was spoken was the main risk factor associated with listeriosis (OR 113, 95% CI 15-undefined). Of non-perinatal cases we identified the following risk factors for listeriosis: prior hospitalization (OR 43, 95% CI 10-183), use of gastric acid inhibitors (OR 94, 95% CI 24-374), and consumption of camembert (OR 47, 95% CI 11-206). Forty percent of cases with prior hospitalization were exposed to high-risk foods during hospitalization. © 2010 Cambridge University Press.

In Australia, state and territory health departments conduct surveillance of foodborne diseases to identify outbreaks and monitor trends. in 2000, the Australian Government established OzFoodNet to enhance the surveillance of foodborne diseases at the national level. Each year in Australia, OzFoodNet records approximately 100 outbreaks of foodborne disease due to a variety of different foods. Since OzFoodNet began, few outbreaks have implicated dairy products, except for outbreaks where people have consumed unpasteurised milk while visiting dairy farms.

The Australian Capital Territory Health Directorate was notified of a food handler with hepatitis E virus (HEV) infection. To guide the public health response, a rapid risk assessment was undertaken to determine the risk of transmission of HEV from the infected food handler to restaurant patrons.The literature on HEV was reviewed and expert advice sought from clinical and public health specialists. This was supplemented by results of a site investigation and a case interview. The risk rating was determined to be the product of the likelihood of transmission and the consequence of the infection.The food handler was likely to have been infectious at the time he was working at the restaurant. He had handled high-risk foods, and the site inspection revealed potential opportunities for transmission. HEV is not common in Australia and it was assumed that the population was non-immune and hence susceptible to the disease. Therefore, there was a low but possible likelihood of transmission of HEV. If infected, HEV has the potential for major consequences in vulnerable populations especially among women who are pregnant. The overall level of risk was considered to be very high.The general public and health practitioners were alerted to enable early identification of symptoms and prompt disease management. There were no secondary cases of HEV associated with this event. In the absence of published guidelines and limited evidence, a risk assessment framework was a useful tool to inform public health decision-making.
