One person has died and dozens were sickened from E. coli infections linked to McDonald's Quarter Pounder hamburgers in 10 states, the U.S.
Centers for Disease Control said on Tuesday. Shares of the company were down about six per cent in extended trading after the CDC said 49 people were sickened by the E. coli O157:H7 strain, which can cause serious illness and is perhaps most often associated with a 1993 outbreak that killed four children who ate undercooked hamburgers at Jack in the Box restaurants.
Everyone interviewed has reported eating at McDonald's before their illness started, and most mentioned eating a Quarter Pounder hamburger, according to the CDC. E. coli prompts recall from P.
