(KMOV) -- 41 firefighters from twelve different agencies battled a fire at a Metro-East grocery store Tuesday morning.
It happened at the Food For Less at 12th and Madison in Madison, Illinois. The fire alarms were struck just after 4 a.m.
It took several hours for crews to get the fire under control due to heavy, thick smoke. No one was hurt and the store was closed at the time.
News 4 talked to the owners of Food For Less. They say everything was fine when they closed for the night Monday. Madison's Assistant Fire Chief David Klee says it appears the fire started in the back of the building. He believes it could be elecrical and an old cooler may be the cause.
The Illinois State Fire Marshal and the health department have taken over the investigation.
