Another in a series of articles by Mr. Lin and the LA Times tracking the problems with fresh, "pre-washed," ready to eat lettuce and spinach: FDA issues spinach warning.

From the article:

An ongoing outbreak of E. coli has killed one person and sickened at least 48 others in eight states, prompting the U.S. Food and Drug Administration on Thursday to advise against eating fresh, bagged  spinach.

Although the investigation remains preliminary, officials suspect the virulent strain of E. coli bacteria came from pre-washed spinach,  infecting people in Connecticut, Idaho, Indiana, Michigan, Oregon, New  Mexico and Utah, said Dr. David Acheson, chief medical officer for the  FDA’s food safety center, at an evening news conference. Wisconsin has  been hit the hardest, with at least 20 cases, including the patient who died.
