McDonald’s will resume production of its Quarter Pounder sandwich this week after its beef patties passed inspection for E. coli.

Four days after the Centers for Disease Control and Prevention issued its alert about an outbreak it claimed was linked to the sandwich, it reported 75 cases of E. coli, 22 of which required hospitalizations, and one death. While the CDC reported these cases across 13 states, McDonald’s shuttered production across 12 states, including Colorado, Kansas, Wyoming, Idaho, Iowa, Missouri, Montana, Nebraska, Nevada, New Mexico, Oklahoma, and Utah, according to its North American Chief Supply Chain Officer Cesar Piña.
