In November 2011, seven people from different dining parties became ill with vomiting and/or diarrhea after eating at a restaurant in Dennison, Minnesota. The implicated meal date was November 12, 2011. Two people visited a health care provider. No one was hospitalized and no one died. One of two specimens collected from patrons tested positive for norovirus GII.

No employees reported having had gastrointestinal illness previous to or on the implicated meal date. During the environmental health assessment, employee handwashing techniques were observed and deemed appropriate. The handwashing station was accessible and properly supplied.

A specific food vehicle was not identified in this outbreak but eating an entree from the Dinner or Saturday Specials menus was statistically associated with illness. Since none of the employees reported being ill, the initial source of the outbreak was not identified.
