According to press reports, the St. Clair County Health Department is investigating the cause of a cluster of gastrointestinal illnesses among customers who dined at the LongHorn Steakhouse in Fairview Heights.
The restaurant has voluntarily closed Wednesday and Thursday.

As of Wednesday afternoon, the department had received 14 reports from people testing positive for shigella. Twelve had dined at the LongHorn Steakhouse at 6115 N. Illinois St. between Sept. 21 and 22. Six cases have required hospitalization, according to the health department.
