Foodborne viral illness - status in Australia

Norwalk-like virus contamination of oysters and orange juice, and hepatitis A virus contamination of oysters have been responsible for large outbreaks of foodborne viral disease in Australia. Rotavirus, adenovirus, astrovirus , parvovirus and other enteroviruses also contribute to the incidence of ga stroenteritis in this country but the role of foods and waters in transmitt ing these viruses is unclear. Protocols for the investigation, surveillance and reporting of foodborne viral illness require further development to en able a more accurate description of the problem. Few laboratories have the capability to analyse foods for viruses and specific training in this techn ology is needed. Management of food safety in Australia largely relies on t he implementation of HACCP principles, but these need to be adapted to addr ess the specific risks from viruses.
