Washington ? The outbreak of E. coli linked to fresh spinach was blamed for another five cases of illness Saturday, raising the number of people sickened to 171, the Centers for Disease Control and Prevention reported.

The number of states affected held steady at 25. So far, 92 people 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.

For more than a week, the Food and Drug Administration has recommended people not eat fresh, raw spinach. State and federal investigators since have traced the contaminated spinach back to three counties in California’s Salinas Valley, and already farm inspections there are turning up possible problems.

The states that have reported infections are Arizona, California, Colorado, Connecticut, Idaho, Illinois, Indiana, Kentucky, Maine, Maryland, Michigan, Minnesota, Nebraska, Nevada, New Mexico, New York, Ohio, Oregon, Pennsylvania, Tennessee, Utah, Virginia, Washington, Wisconsin and Wyoming.
