Yesterday the Illinois Department of Public Health released a brief update on the Subway Salmonella outbreak.  The update states:

“Confirmed cases of Salmonella serotype Hvittingfoss – 60. Age range of confirmed cases: 2 to 88.

According to the Illinois Department of Public Health, the investigation is ongoing and numbers will be updated Wednesday, June 9.

A specific food source has not been identified as the source of the Salmonella outbreak, but the U.S. Food and Drug Administration and Centers for Disease Control and Prevention are working with Illinois state and local public health officials and Subway restaurants throughout the state to determine the source of contamination.

Salmonella Hvitingfoss is an uncommon serotype of Salmonella; typically only one to two cases of the serotype are reported in Illinois per year.
