In chronic-wasting disease (CWD), a cousin of mad-cow disease and already present in North America, deer brains turn spongy, causing the animal to lose weight and die.
It is contagious among deer and reindeer but not known to pass from animals to humans.
The disease was detected for the first time in Europe last year in Norway, with three known cases of reindeer infected in a single herd and two other cases among moose - though the latter cases were considered to be of less concern since moose do not live in herds.
In a letter sent today to the authority, the agriculture ministry gave the green light "based on the knowledge we have today and the unanimous recommendations of experts."
