Interpretive summary: This study evaluates the potential of electron beam technology to inactivate foodborne viruses within oysters. Electron beam (E-beam) is ionizing radiation generated from electricity rather than a radioactive source. Until this report, its potential for sanitizing raw shellfish had not been investigated. While a 10 fold reduction of a human norovirus surrogate and hepatitis A virus is demonstrated using E-beam on virus contaminated oysters, this reduction is judged to be insufficient to warrant the application of E beam as an intervention technology for shellfish that may be contaminated with norovirus or hepatitis A. This study does document the degree of virus inactivation that could be expect to occur concurrently if E-beam treatments were used as an intervention for pathogenic bacteria.
