In June 2015, members of a large dining party became ill after eating at La Tropicana restaurant located in Lawrence, Kansas. Other illnesses were reported after eating at the restaurant on June 2. A total of 10 people were identified as outbreak cases. One stool specimen tested positive for norovirus genogroup I. No one was hospitalized and no one died.

On June 3 the restaurant was inspected by the Kansas Department of Agriculture. The inspection revealed one priority violations and two priority foundation violations. Diarrheal illness was reported by 4 of the 11 employees — three servers reported illness onset on June 2 and June 3, and one cook reported illness onset on May 31. The dates and times each employee worked was not reported. It was noted that bare hand contact was necessary to retrieve a utensil inside of the dry bean container, and that clean forks located at the wait station were stored upside down, requiring staff to touch the food surface end of the forks to remove them from their container. Information was provided to educate staff on foodborne illness and personal illness restrictions.
