The first case was found at the end of June in the village of Montgardin where it killed six cows.
Since then, 50 more animals have died but there has been no evidence to suggest it has been transferred to humans.

Senior Hautes-Alpes official Serge Cavalli said animals were being vaccinated at affected farms in the region.

Mr Cavalli said animals were being vaccinated at affected farms in the region.
The signs of anthrax in animals include flu-like symptoms, coughing up flood, chest discomfort and a shortness of breath.

No human has been affected by the infection so far according to the French authorities.
The farms that have been affected have been banned from production for at least three weeks while the farms are disinfected.
