Firefighters are investigating the cause of a fire at a fruit packaging plant. The cause of the fire at Roche Fruit Company is still under investigation. The fire started Friday night around 8:30 p.m. Over 500 wooden bins were damaged. The fire department says the property owner helped move several of the bins - something that kept the fire from spreading. A company manager says the bins were empty and that no employees were working at the time. No injuries were reported in relation to this incident. The City of Yakima also says the fire was contained fairly quickly.
