The 12th case of E. coli in the Columbus, Ohio area has health officials officially calling it an outbreak.

They say none of the cases have a a genetic link to the 52-year old Gahanna, Ohio who died from E. coli compliations on May 27th.

But since then, central Ohio has seen a dozen more cases and they are searching for a source of the bacteria.

The Columbus Dispatch says a team of health departments that includes the city of Columbus; Delaware, Fairfield and Franklin counties; and the state has come together to investigate the outbreak.

The new case is from Fairfield County.

Also, a fourth case was genetically linked to three others through state lab testing, meaning that those cases — all discovered within Franklin County — are likely from the same source.
