Major HPAI outbreak hits Mexican poultry state

Highly Pathogenic Avian Influenza (HPAI) has been found on three commercial poultry farms in the Mexican state of Jalisco, according to a report submitted to the OIE.

In total over one million birds have been found susceptible across the three farms with over 200,000 deaths and 60,000 birds have been destroyed.

According to the report, clinical signs were determined on 13th June. The birds, aged 32, 72, 75, 84 and 94 weeks old showed signs of gasping, depression, lethargy, drooping wings, prostration, fever and death. Epidemiological investigation is on-going to establish the extent of the problem and the source of infection in order to implement additional measures to rapidly resolve the problem. The source of the outbreak or origin of infection is as yet unknown.

Officials have also limited poultry movements near the outbreak area and are testing birds at commercial farms, backyard flocks, and poultry markets. They are also assessing biosecurity practices and overseeing depopulation efforts at the affected farms, according to the OIE report.

Jalisco state, in western Mexico, is the country's top egg producer.

    HPAI could be controlled by recombinant vaccine (Pox+H1) given to newly hatched chickens (and other poultry) by nebulization already in hatchery.

    Through disinfection is needed to avoid aerial spread.
