Officials praise teamwork in response to deadly Texas dairy farm explosion.

An explosion at the South Fork Dairy Plant in Dimmitt, Texas, is under investigation by the Texas State Fire Marshal. The fire was the biggest the Castro County Sheriff had ever seen, and one person was rescued from the building. The cause of the fire is still unknown, but it is believed to have been caused by insulation catching fire and spreading. At least one person is receiving treatment for their injuries at the University Medical Center in Lubbock.
