Update, 8:30 p.m.: One body was recovered from the International Nutrition building about 5:15 Monday, Interim Fire Chief Bernard Kanger said during an 8 p.m. press conference.
He did not identify the person because the family had not yet been notified.
Kanger said extreme weather conditions — wind, cold and occasional snow — forced crews to suspend recovery efforts Monday evening.
Firefighters were working Monday to stabilize a south-central Omaha plant before re-entering it.
The industrial accident at International Nutrition, 7706 I Plaza, left two dead and sent 10 others to area hospitals.
Around 5:30 p.m., a police spokeswoman said authorities believe everyone in the building had been accounted for. At least 38 people were at work at the time of the accident, Interim Fire Chief Bernard Kanger said at a 3 p.m. press conference.
