Authorities say about 1,000 pigs died in a fire at an eastern Iowa hog containment operation.
The fire was reported about 1 p.m. Friday at Mipa Hog Farms, which sits about 10 miles west of Columbus Junction.
There were no reports of human injuries.
The operation includes eight connected buildings spread over 20 acres. By the time firefighters arrived, two farrowing houses were fully engulfed.
Officials say 500 to 600 of the pigs killed were sows. The rest were piglets.
The fire cause is being investigated.
