Twenty-four cases of E. coli across Michigan have been linked to a strain that sickened students at Michigan State University earlier this month.
     
A common commercial food source is suspected but has not yet been identified.
     
State health officials say one case in New York has been linked to the same strain but appears to be isolated. The Centers for Disease Control and Prevention say E.coli cases in three other states share the same genetic link as those in Michigan. Illinois and Ohio have two cases each, and Oregon has one.
     
Of the 24 cases in Michigan, seven are at Michigan State, five are inmates at the Lenawee County Jail, three are from the University of Michigan and the rest are from Macomb, Wayne, Kent, St. Clair and Oakland counties.
     
Nine people have been hospitalized, but none have died.
