WALLULA, Wash. — Some workers have returned to the Tyson Foods plant Wednesday, one day after a large grease fire temporary shut down production at the beef slaughtering and processing plant in Wallula.

The Tri-City Herald reports (https://goo.gl/3xYKjZ) the fire broke out around 4 a.m. Tuesday in the area where fat is separate from the animal at the facility southeast of Pasco. Firefighters from several agencies responded.

A company spokeswoman said Wednesday the plant was not operating at the time and no one was hurt. She says the fire was limited to the rendering area of the plant.

Tyson Foods says it is still assessing the situation but is running its processing operation Wednesday. It hopes to resume full production as soon as possible.

The operation is Walla Walla County’s second largest employer.
