Probabilistic risk model of norovirus transmission during handling and preparation of fresh produce in school foodservice operations

Human noroviruses (NoV) are recognized worldwide as important pathogens and the primary cause of food borne disease outbreaks from contaminated food in the U.S. They are often transmitted by infected food handlers manipulating foods during preparation, such as fresh fruits and vegetables. This paper provides a study to model the transfer of NoV between food handlers and vegetables during salad preparation in school food services based on direct observation data.
