The outbreak of E. coli has now spread to half the states. As of Friday afternoon, infections had been reported in 166 people in 25 states. That's up from 157 victims in 23 states on Thursday, according to the Centers for Disease Control and Prevention.

The infection has been associated with consumption of fresh spinach and public health officials are urging people not to eat raw spinach.

Of those infected, 88 have been hospitalized, including a Wisconsin woman who died. Two other deaths have been reported in suspected cases — a child in Idaho and an elderly woman in Maryland — but those cases are still being investigated.
