A Tyson plant in Sanford is closed after a weekend fire, officials said.
When firefighters arrived about 8:40 a.m. Saturday, they found the trailer portion of one tractor-trailer on fire at the loading dock.
The fire spread to two other trailers and the loading dock itself before being extinguished, officials said.
All of the employees were outside when firefighters arrived, but the plant remains shut down for cleanup, according to the Sanford Fire Department.
