At least 300 workers were told to stay home Wednesday after a fire damaged the rendering portion of the Wallula Tyson Foods plant on Tuesday.
About 1,100 other workers returned to work, said Caroline Ahn, public relations manager at Tyson Food.
Officials continue to assess damages at the plant as work continues on the processing floor, though no new animals are coming to the plant, she said.
“I think it’s going to take a few days,” she said. “It’s hard to tell with things going on at the plant to get a concrete timeline.”

The fire started about 4 a.m. in part of the facility where fat is separated from animals. No damage estimate or possible cause was released.
