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.
The report confirming that the Avian Influenza outbreak in Jalisco notified last week to be highly pathogenic Avian Influenza H7N3 is reason for regional and Belize alert. Further testing has shown that the intravenous cerebral pathogenic index is greater than 1.2 and thus according to the OIE it is highly pathogenic avian influenza (HPAI). Mexico last reported HPAI in June 1995.
This is considered an emergency for the region hence all poultry farmers should step up biosecurity especially areas bordering Mexico who need to take even more strict measures.
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.
