One person is dead and 48 others across 10 states have been sickened in an E. coli O157:H7 outbreak that appears to be linked to McDonald’s Quarter Pounders and the slivered onions used on the burgers, according to the Centers for Disease Control and Prevention.
McDonald’s has paused distribution of the slivered onions and removed Quarter Pounders from the menus of restaurants in areas known to be affected. As of now, those areas include Colorado, Kansas, Utah, and Wyoming, as well as portions of Idaho, Iowa, Missouri, Montana, Nebraska, Nevada, New Mexico, and Oklahoma.
However, the CDC was quick to note that the size and span of the outbreak are likely larger than is currently known. “This outbreak may not be limited to the states with known illnesses, and the true number of sick people is likely much higher than the number reported,” the agency said in its outbreak notice posted Tuesday afternoon.
