Organic samples (especially brain tissue) were sent to the Norwegian Veterinary Institute for research to have the correct answer about how the animals died. The animals should be tested not at least for the severe disease CWD (Chronic Waste Diesease), also called skrantesyke, which was first discovered in Norway on moose and caribou earlier this year. CWD has never infected from animals to humans. “Reindeer are pack animals and are often close together. During a heavy thunderstorm, they may have gathered even closer together out of fear,” spokesman Knut Nylend of the Norwegian Nature Inspectorate explained what is believed about this unprecedented situation. “I don’t remember hearing about lightning killing animals on this scale before,” he added. The agency is now discussing what to do with the dead animals but normally they are just left where they are to let nature take its course, he said.
