(AP) -- The Centers for Disease Control and Prevention says new cases have been reported in California, New York and Ohio. Cases were reported in Minnesota earlier, while the majority of illnesses have been in Oregon and Washington.
The agency says the investigation is ongoing to determine the specific food that is linked to the illness.
So far, the CDC says 45 people have been infected in relation and that 16 of them have been hospitalized. There have been no deaths.
Late in October, Chipotle Mexican Grill closed 43 restaurants in Oregon and Washington after health officials discovered most of the people sickened in an E. coli outbreak had eaten at the chain's restaurants. The restaurants have since reopened.
