Two instances of sub-clinical Newcastle Disease have been detected in separate commercial flocks in Central Mexico, according to reports submitted to the World Organisation for Animal Health (OIE).
The first report describes a positive reaction to routine surveillance at a farm at Col. Montoro in the region of Aguascalientes on 26 October. All 850,816 birds were destroyed.
In Jalisco, 30,000 susceptible birds were destroyed at a commercial broiler farm at Road Lagos de Moreno-San Luis Potosí.
In both instances the farms have been depopulated and cleaning and disinfection activities have been carried out. In addition the properties have been quarantined with movement of birds restricted.
