The Kane County (Illinois) Health Department issued a press release today indicating that the outbreak of SalmonellaTyphimurium at the Portillo’s restaurant in St. Charles, Illinois may be linked to salad.  According to KCHD the “weight of the evidence leans toward ingestion of salad” as the cause. 

The updated number of persons ill stands at 15, with 8 from Kane County, 4 from DuPage County, 1 from DeKalb County, 1 from Chicago, and one from Minnesota.  Two emploees of the restaurant tested positive for Salmonella, but health officials see them as “victims” of the outbreak as opposed to the cause.  

The onset date of illnesses ranged from April 5 through April 30, 2011.  Three people were hospitalized.
