Coca-Cola CEO James Quincey said the company doesn't expect an E. coli outbreak linked to McDonald's to hurt the beverage company's sales. McDonald's is Coke's largest restaurant customer, and the two companies' symbiotic relationship has existed for nearly seven decades. On Tuesday, the Centers for Disease Control and Prevention announced that it has linked an E. coli outbreak in 10 states to McDonald's Quarter Pounder burgers. Both ingredients are unique to the Quarter Pounder burgers, although cooking the patty at the correct internal temperature should kill the bacteria. The outbreak comes as consumers broadly have been spending less at restaurants, hurting both McDonald's and Coke.
