Brunost the Norwegian dairy co-operative Tine, who market a total of 13 varieties, as well as three types of prim and three types of pultost. The second-largest is Norwegian dairy company Synnøve Finden, which market two varieties of brunost, as well as two varieties of prim. There are also a number of smaller, artisanal producers, mainly in Norway and in the US. Mysost are a family of cheese-related foods made with whey and milk and/or cream. Because the main ingredient, whey, is a byproduct of the cheese making process, brunost is not technically cheese, and it does not taste like cheese.
Summit Tunnel fire top of the shaft. Unable to get close enough to safely fight the fire directly, the fire brigades forced high-expansion foam into ventilation shafts far from the fire. This created blockages that starved the fire of oxygen. By mid-afternoon the next day, the inferno was no longer burning, though the fire was by no means knocked down. Petrol continued to leak from the derailed wagons through the tunnel drainage and ballast and the vapour sporadically reignited when it came into contact with the hot tunnel lining. Two hundred people were evacuated from their homes and workplaces in Walsden in response.
