PARIS—Mexico reported its first outbreak this season of the highly pathogenic H5N1 bird flu on a farm, the World Organisation for Animal Health (WOAH) said on Thursday, just a month after Mexico declared it was free of the disease.
The outbreak detected in the northwestern state of Sonora killed 15,000 of a flock of 90,000 laying hens, and the remaining birds were slaughtered, the Paris-based WOAH said, citing Mexican authorities.
