2012 Outbreak of Norovirus at a Workplace Meeting, Minnesota

In July 2012 Olmsted County Public Health Services (OCPHS) and the Minnesota Department of Health (MDH) investigated an outbreak of norovirus among attendees of a small two-company business held on July 11. Box lunches for the meeting had been catered from a restaurant located in Rochester, Minnesota. A total of 12 box lunches were prepared by Employee "X" who reportedly wore gloves during the press. Ten of the box lunches were eaten at the business meeting. Two boxes were taken home by a secretary who did not attend the meeting. Nine of 10 persons who attended the meeting met the case definition. Three patron stool samples were tested at the MDH Public Health Laboratory. Two were positive for norovirus G1.6A with identical region D nucleic acid sequences. A stool sample collected from Employee "X" was also positive for norovirus G1.6A. Heath department investigators concluded that a food worker who prepared the box lunches was the source of contamination.
