The onion supplier behind a deadly E. coli outbreak linked to McDonald's Quarter Pounders this past fall had numerous health and sanitation violations, including employees with unwashed hands, dirty equipment, and puddles of Listeria bacteria. That's according to a Food and Drug Administration inspection report that was obtained by CBS News via a Freedom of Information Act request. On October 22, the Centers for Disease Control and Prevention announced the outbreak investigation, which at that time had only been linked to 48 illnesses across 10 states, including one death.
