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.
The seven people have tested positive for Typhimurium Salmonella. Most persons infected with Salmonella develop diarrhea, fever, and abdominal cramps 12 to 72 hours after infection. The illness usually lasts 4 to 7 days, and most persons recover without treatment or ever visiting a doctor. However, in order to assist in the investigation, the Health Department is recommending that anyone who has had these symptoms visit their personal physician.
