Lois Collins of the Deseret Morning News has reported more on the Wendy’s outbreak:

Wendy’s restaurant chain is being sued by a Weber County family after the Weber-Morgan Health Department identified a North Ogden Wendy’s as the probable link in four confirmed E. coli infections in June.
Seattle law firm Marler Clark and Salt Lake attorney Todd Gardner of Bateman Goodman and Gardner filed the lawsuit Friday in Weber County District Court on behalf of William and J. Corey Cohron and their two sons.
According to William Marler, the complaint seeks “compensation for the family’s significant medical-related expenses, economic losses, pain and suffering and emotional distress.”
The complaint filed by Marler Clark says that Corey Cohron ate a Wendy’s salad at the conference and later became ill with symptoms of E. coli infection, including diarrhea. Other family members subsequently developed symptoms as well, most of them not requiring medical treatment. But Wil Cohron, 7, suffered severe infection and was taken to an emergency room July 12. He was in the hospital for two days. He later was rehospitalized and tested positive for E. coli.
