2013 Norovirus Associated with a Private Potluck, Watertown, Minnesota

On October 9, 2013 members of a Watertown, Minnesota cross country team became ill with norovirus following a potluck held at a private home. A school nurse reported that 14 members of the team were ill. Symptoms noted were vomiting, diarrhea, and fever. Foods served at the potluck included a pasta dish with meatballs, snicker salad, Caesar salad, garlic bread, caprese salad, lasagna, potato salad, grapes, a fruit bowl and desserts. All foods were supplied by private parties. Of the 24 potluck attendees, 10 met the case definition. Three participants submitted stool specimens for testing at the Minnesota Department of Health Public Health Laboratory. All three specimens were positive for norovirus GII. Nucleic acid sequencing confirmed that all three positive stool samples had identical sequences. Consumption of the fruit bowl was the only item significantly associated with illness. This item was brought by one of the party attendees who reported to the school nurse that there was gastrointestinal illness in their household in the days preceding the potluck.
