A fire that started in the chimney of a bread-baking oven damaged the bakery at the Ypsilanti Food Co-op early this morning.

No one was injured, but the bakery at 308 River St. in Ypsilanti will be closed while the damage is assessed and necessary repairs are made. The co-op itself will remain open, said co-op manager Corinne Sikorski, who is also one of the building owners.

An employee riding to work on a bicycle saw smoke coming from around the chimney and called 911, Sikorski said. The employee and the co-op's baker then alerted the tenants in the apartment above, who got out safely.

Ypsilanti Fire Capt. Dan Cain said 10 Ypsilanti firefighters, as well as three from Ann Arbor, fought the blaze and had it under control within about 40 minutes of receiving the call at 4:35 a.m. He said smoke and flames were visible from the back of the building when firefighters arrived.

Cain estimated damage at $15,000. He said damage was mostly contained to the bakery area.

Sikorski said the co-op had torn down the original brick wood-burning oven built in 1989 and rebuilt it. Employees were in the process of starting up the new oven when something malfunctioned.
