Abstract

Oysters contaminated with human enteric viruses from sewage are implicated in foodborne outbreaks globally. Bacteriophages have been identified as potential indicators for these viruses, but have not been used in shellfish management outside of the USA. This study aimed to determine the background levels of F-RNA phage in five Australian oyster growing areas with a history of sewage spills and closures, over an 18-month period. In addition, oysters from five growing areas impacted by adverse sewage events were investigated for F-RNA phage, Escherichia coli, norovirus (NoV) and hepatitis A virus (HAV). F-RNA phage ≤ 60 pfu/100 gm shellfish flesh were found to represent a conservative background level in the surveyed areas. Following two of the five sewage spills, elevated phage levels were observed in most sample sites less than 4 days post spill. By 7 days, most sites from all events had phage
