Mexico: a new outbreak of HPAI H5 at a commercial poultry farm

31 October, 2022

An outbreak of HPAI H5 at a large commercial poultry farm in Montemorelos, Nuevo Leon affecting 60,000 birds.
Mexico's first case of the virus was detected in a wild bird in the Metepec district to the west of the capital Mexico City. Another H5N1 case was found in a wild bird in Tijuana in Baja California state and in a small chicken, family-run farm in Chiapas in the country's south.
The discovery at the chicken farm comes just over a week after Mexico reported its first-ever case of H5N1 avian influenza, to the WOAH.
