Cargill’s beef processing plant in Schuyler, Nebraska closed early Thursday due to a fire and ammonia leak.
Reuters reports the cause of the fire and leak is currently unknown and damage to the facility is still being assessed.
The plant processes roughly 5,000 head of cattle a day.
A Cargill spokesman said the company was working with the United States Department of Agriculture to determine when the plant can reopen, which could be as early as Friday.
