Chipotle has temporarily closed dozens of its restaurants in Washington and Oregon out of an abundance of caution after an E. coli scare. No one has died in the reported cases of infection, the Washington State Department of Health said. Seven of the Washington patients and one Oregon patient were hospitalized. The source of contamination has yet to be exactly determined, the department said, but 19 cases in Washington and three cases in Oregon have been linked to a handful of locations of the Mexican-themed restaurant chain. Although cases are being investigated in connection with six locations in the Seattle and Portland areas, Chipotle has temporarily closed 43 stores.
