Evaluating the risk of developing norovirus variants with enhanced recalcitrance to disinfectants as a consequence of improper sanitation practices

Objective 1. Concealed observation of members within food service establishments to assess the current practices of cleaning and disinfectant techniques using approved sanitizers (research and extension).Objective 2. Investigate the potential for Tulane virus to develop enhanced recalcitrance to serial sub-fatal disinfectant treatments (quaternary ammonium and PAA), as well as the potential evolutionary mechanisms by which such enhanced recalcitrance occurs if observed (research)Objective 3. Develop a risk model that can be used as a communication method for understanding norovirus risk in a food retail environment.
