on the outbreak of E. coli linked to fresh spinach, raising the number of people sickened to
, the Centers for
Disease Control and Prevention reported. So far,
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. Since the outbreak was reported two weeks ago, 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. On Friday, officials said
spinach grown anywhere outside that area is safe to eat — but industry needs to figure out how to let consumers
know the origin of what they're buying before the green can return to sale, said Dr. David Acheson of the FDA's
Center for Food Safety and Applied Nutrition. The 25 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.” Suppose the population of interest is the
people sickened by E. coli in fresh spinach, and a
of these 173 people was selected for additional study.
out of the 22 people selected for the sample
have been hospitalized.
