State health officials say E. coli has made at least seven people ill in Stephens County.
Public health spokesman Dave Palmer said that no source has been identified. He said some of those who became ill had to be hospitalized, but all are recovering.
The state is interviewing them to track what and where they've eaten in an attempt to find common patterns.
Health officials say preventive measures include practicing good hand-washing and hygiene, washing raw vegetables, and cooking meat properly.
