The quarantine in effect for several weeks at the Saginaw Correctional Facility near Freeland has been lifted.
An outbreak of shiga toxin-producing E. coli sickened 96 people over the last month.
MLive.com reports Wednesday (http://bit.ly/RiAwKe) the quarantine was lifted this week.
Michigan Department of Corrections spokesman John Cordell says normal operations have resumed at the Saginaw-area facility.
The quarantine began on Aug. 31. Questionnaires were given to inmates to determine what they had eaten, and a review was done of all items on the menu at the time the illnesses began.
The most probable source was chicken salad that was prepared by the inmates and served at the prison's cafeteria, but officials can't say for sure it was the cause of the outbreak.
According to the Michigan Department of Corrections website, the 43-acre facility in Tittabawassee Township, Saginaw County, was built on a 142-acre site and is comprised of 11 main buildings totaling about 303,850 square feet. The facility includes three Level II buildings, three Level IV buildings, and one Level I building along with buildings for education, programs, administration, food service, healthcare and maintenance.
