Mexico’s latest case of highly pathogenic avian influenza (HPAI) was confirmed in a commercial layer farm in San Miguel el Alto, in the state of Jalisco.

According to a report from the World Organisation for Animal Health (WOAH) there were 200,000 birds in the flock.

The case was detected as a result of active surveillance, due to the presence of clinical signs and lesions compatible with the disease on a neighboring farm. Testing revealed that the strain of HPAI found in these birds was of the H5N1 serotype.

WOAH stated that the believed source of infection is contact with infected wild birds.
