The Dutch Ministry of Economic Affairs, Agriculture and Innovation announced that avian influenza has been discovered on a poultry farm in Schore, Netherlands. Approximately 127,500 hens are planned to be culled.

It’s potentially the H7 variant, which can mutate into a dangerous, hen-killing variant, and is caused by wild birds’ stools, according to the ministry.

During the evacuation, which started March 25 at 8 a.m., there’s a prohibition of transportation in a zone of 1 kilometer around the farm of poultry, eggs, poultry stools and animal feed.
