A recent report from the World Organization for Animal Health revealed three more cases of pathogenic avian influenza in commercial poultry flocks in Mexico. All three affected operations involved broiler flocks and collectively the new cases resulted in the loss of 826,800 birds. Two of the newly reported cases were in San Francisco de Los Romo. The affected flock involved 208,000 chickens and another 298,800 birds. The other case involving 320,000 chickens was located in Asientos. All three cases were confirmed in February after detection through active surveillance. However, information on these HPAi samples did not appear on the WOAH website until May 24. Each of these cases involved the H5N1 serotype. The same report showed that HPAI was also confirmed in a backyard flock in Chapa de Mota. There were 90 birds in that flock. Implemented control measures include stigma, quarantine, zoning, surveillance and disposal of carcasses, by-products and waste inside and outside the restricted zone. According to Woah figures, Mexico had 30 confirmed cases of HPA in commercial poultry, resulting in the loss of approximately 6.5 million birds.
