STORM LAKE, Iowa (KTIV) - Six hundred workers at a turkey plant in Storm Lake, Iowa are still waiting to find out when they could go back to work.
Authorities say the fire on Saturday caused substantial damage, and Hillshire Brands closed the plant through Tuesday night.
The Storm Lake fire department and the state fire marshal, working together on the investigation, say they're not ready to release any information about the investigation just yet.
KTIV's source at Hillshire Brands' corporate office says the company is holding a meeting for all employees regarding the fire on Wednesday.
Firefighters were called to the plant at about 7 p.m. on Saturday and found a massive fire.
It took nearly three hours and fire departments from four surrounding communities to contain.
The firefighters continued to put out spot fires through Sunday afternoon.
Investigators say that a 50 by 50 section of the roof caved in and there's significant damage throughout the plant.
Hillshire Brands closed the plant through Tuesday night for sure, but say that reopening is very flexibile and the investigation hasn't revealed anything concrete.
"There are some materials and some debris that need to be moved so that we can take a closer look at the area inside the plant. So we're anticipating that their investigation will go on for a few more days before we get any preliminary results," Mark Prosser, Storm Lake Public Safety Director said.
All workers that were inside at the time the fire started were safely evacuated. Corporate doesn't have a confirmed number of how many were inside at the time of the fire, but says the plant was likely only occupied by a handful of maintenance workers.
Officials also alerted people in a three block radius of the fire that they were evacuating the area voluntarily, but only because of the smoke and odor, not because of potential danger.
