A second bag of spinach contaminated with toxic E. coli bacteria has been found in Utah, and regulators hope it will offer clues about an outbreak that has sickened 173 people and killed as many as three.
A bag of spinach found in New Mexico last week helped experts pinpoint suspect farms in three counties in California's Salinas Valley. The Food and Drug Administration said spinach grown outside of those counties is safe to eat.
In a statement Sunday, the FDA said the Utah and Salt Lake Valley health departments confirmed that E. coli O157:H7 was found in a bag of Dole baby spinach with a use-by date of Aug. 30.
The FDA said 173 cases of illness due to E. coli have been reported to the national Centers for Disease Control and Prevention, including 27 with a serious type of kidney failure called hemolytic uremic syndrome.
