Salmonella Typhimurium Outbreak Linked to St. Charles Portillo’s

The seven people have tested positive for Typhimurium Salmonella.

The Kane County Health Department, and the Illinois Department of Public Health Laboratories and other local Health Departments, have reported a recent increase in Salmonella ser. Typhimurium in Northeastern Illinois. In approximately the past two weeks, 10 cases of Salmonella ser. Typhimurium with a matching PFGE, or genetic, pattern have been reported In Illinois. This pattern is rare in Illinois. At least two additional cases of S. Typhimurium are pending the PFGE results. Cases in other states have also been identified.

While the investigation is ongoing, a common potential link is that seven of the people affected reported having eaten at Portillo’s in St. Charles during the month of April. No specific food item has been identified to be source of the illness.
