Technical Report: Review of Quantitative Risk Assessment of foodborne norovirus transmission

An internal FSA review of the Norovirus Attribution Study (NoVAS)

In line with government-wide recommendations on the quality assurance of models used to inform government decision-making, an internal review was conducted by the FSA following NoVAS.

This resulted in a technical report, which confirmed that the model structure was fit for purpose, and made use of the latest data (that had become available after the NoVAS modelling work had been completed).

Consequently, findings were updated on the relative contribution of five pathways (oysters, lettuce, raspberries, meals eaten out and takeaways) to the total number of symptomatic foodborne norovirus infections in the UK.
