Initial investigations by the Centers of Disease Control and Prevention indicate that the contamination likely came from chopped romaine lettuce from the Yuma, Arizona, growing region. No common grower, supplier, distributor or brand has been identified yet. The chopped romaine lettuce in question was consumed at restaurants and in private homes.
Officials at the Idaho Division of Public Health and multiple Idaho public health districts are advising people who have pre-chopped romaine lettuce from Yuma or an unknown source to throw it out, even if they have previously consumed the romaine without becoming ill.
The CDC confirms that there have been at least 35 cases of E. coli infections in 11 states tied to the pre-chopped romaine lettuce thus far.
