Five confirmed cases of salmonella have been reported to the health department since Feb. 28.

A press release from Public Health administrator Toni Corona said four people affected had reported eating at Vanzo's beginning Feb. 21. An investigation is ongoing and a specific source or food item associated with the outbreak has not been identified.  The restaurant at 132 N. Main St. Edwardsville, voluntarily closed over the issue. People who ate at the restaurant suffered diarrhea, fever or nausea/vomiting afterwards may be implicated in this outbreak.  The health department is interviewing both ill and well patrons who frequented Vanzo's between Feb. 21 and March 6.
