Yucatán, Mexico reports H5N1 avian influenza outbreak in commercial farm

The Mexican Secretariat of Agriculture and Rural Development (Sader) has confirmed a highly pathogenic avian influenza (H5N1) outbreak at a commercial egg production farm in Umán, Yucatán. The detection followed an unusual mortality report of 862 birds within a population of 225,860 laying hens.

In response, the National Service for Agrifood Health, Safety and Quality (Senasica) implemented international sanitary protocols. These measures include a definitive quarantine of the production unit, a 10-kilometer risk perimeter, the total depopulation of the farm, and the sanitary disposal of all birds and contaminated materials. Authorities are also conducting inspections of nearby egg, fattening, and breeder farms to prevent further spread.

Sader stated that the affected farm represents only 0.09 percent of the national poultry inventory, ensuring that the national supply of eggs and chicken remains stable. Officials emphasized that the consumption of poultry products is completely safe. Investigations are ongoing to determine the origin of the contagion, with specialists inspecting local water bodies due to the presence of migratory birds during the winter season.
