Key points
CDC and public health officials in several states are investigating a multistate outbreak of E. coli infections linked to frozen blueberries. If you have recalled blueberries in your home, throw them out or return them to the store.
Where sick people live
This map shows where the 12 people in this E. coli outbreak lived.
This outbreak may not be limited to the states with known illnesses, and the true number of sick people is likely much higher than the number reported. This is because many people recover without medical care and are not tested for E. coli.
