Mexico reported an outbreak of the highly pathogenic ​H5N1 bird flu on a ‌farm in the Yucatan Peninsula, its first outbreak in poultry in ​more than two years, ​the World Organisation for Animal Health (WOAH) ⁠said in a report ​on Friday, citing local authorities. 

The ​spread of avian influenza, commonly called bird flu, has raised concerns among governments ​and the poultry industry ​after it ravaged flocks around the world ‌in ⁠recent years, disrupting supply, fuelling higher food prices and raising the risk of human transmission. 

The ​H5N1 virus ​was ⁠detected in a flock of 225,860 laying hens ​in the town of ​Uman, ⁠the Paris-based WOAH said, citing a report from Mexican authorities. ⁠All ​birds were subsequently ​culled as a precaution. [emphasis added]
