2012 Norovirus at a Restaurant in Arden Hills, Minnesota

In January 2012 Minnesota Department of Health (MDH) and Ramsey County Environmental Health (RCEH) investigated an outbreak of norovirus among dining patrons of a restaurant located in Arden Hills, Minnesota. Three of five individuals from two different households became ill after their meal on January 8. The median incubation period for cases was 29 hours (range, 24 to 33 hours). Duration of illness information was limited. Stool samples submitted by two ill patrons tested positive for norovirus GII. RCEH sanitarians interviewed 18 restaurant employees. Three reported illness with reported onsets of January 4, 7, and 9, respectively. However, none of these employees were on January 8. The sanitarian observed good hand hygiene and proper glove use. Investigators concluded this was a norovirus outbreak associated with a restaurant in Arden Hill. A specific food vehicle was not identified. The source of the contamination was likely an infected food worker.
