A correctional officer reported a possible foodborne outbreak to the Office of Environmental Health in Arizona when a number of inmates presented with gastrointestinal distress. A laboratory investigation found the causative agent to be Norovirus. A case-control study indicated the vehicle to be sausage served at lunch two days before the report was made. An environmental investigation of the prison's meal preparation area found many violations. Dishes were washed in dirty water and not rinsed; ill food workers had worked prior to the outbreak. Importantly, the temperature control sheets reported the sausage had not been heated to the proper temperature prior to serving.

Seventeen people were ill. No one was hospitalized and no one died.
