One death and dozens sick after severe E coli outbreak linked to McDonald's Quarter Pounder in several US States

Multiple cases of E. coli infection have been reported in the US, with 10 hospitalizations, including a child, with one reported case of hemolytic uremic syndrome. All infected individuals consumed McDonald's before showing symptoms, with the majority reporting eating Quarter Pounder hamburgers. CDC is investigating, and McDonald's has temporarily stopped using slivered onions and 1/4 lb beef patties in some states. However, the exact contaminated food ingredient has not been confirmed yet. The affected states include those in the western and Midwest regions.
