Fire crews from more than two dozen departments battled the fire that broke out Saturday night at Commodity Resource Corp. in the Livingston County town of Caledonia, 15 miles south of Rochester.
The company says the site is the largest dairy feed manufacturing facility and dry fertilizer distribution center in the region. The plant was closed at the time of the fire.
On Tuesday, Caledonia Deputy Chief John Murray told media outlets the fire was caused by spontaneous combustion. That’s the same thing that sparked a September fire at a Cargill feed plant in Salem near the Vermont border.
