Geothermal hot water has been used to pasteurize milk at Medo-Bel Creamery in Klamath Falls for over 30 years. According to the owner, Elmer Belcastro, this is the only known creamery in the world that pasteurizes milk by geothermal means. Geothermal hot water is also used to heat the 30,000 square foot building, which amounts to a substantial savings during the winter months
