An update on viruses in the food chain

In 1994, in response to the outcomes of a joint Advisory Committee of Microbiological Safety of Food (ACMSF) and Steering Group on the Microbiological Safety of Food (SGMSF) meeting, a Working Group was set up to investigate the science and epidemiology of Foodborne Viral Infections. The Working Group assessed the risk from viruses that were believed to be the primary cause of foodborne illness. This report provides an update to this information and provides a new focus on the viruses which are currently the major route of foodborne illness. Since the publication of the 1998 report, with the exception of two minor risk assessments on hepatitis E and avian influenza, no formal review on viruses had been performed by the ACMSF. It was decided that as significant developments had been made not only in the detection of foodborne viruses, but also in the amount of information obtained from the Infectious Intestinal Disease (IID) Study in England (published in 2000), which indicated a significant disease burden from enteric viruses in the community, it was important that an Ad-Hoc Group was convened to revisit these issues and to provide an update to the 1998 risk assessment.GB; en; ACMSF@foodstandards.gsi.gov.u
