Regarding sacrifice, 2,025,449 broilers have been culled in Jalisco and 1,241,265 hens have been culled in Guanajuato. Furthermore, in the quarantine area of over 19,000 km2, covering the states of Guanajuato and the boundaries of Jalisco and Aguascalientes, health surveillance and counter-epidemic measures continue. There are 13 checkpoints in the sanitary cordon to prevent mobilization without official control of live birds, their products and byproducts, and poultry manure.

Senasica authorized vaccinating birds in nine federal entities for the prevention of the AH7N3 avian influenza virus. The priority is to vaccinate birds with long lifespans, such as parent stock, breeders, as well as laying hens.

"In the states of San Luis Potosi, Mexico, Hidalgo, Tlaxcala, Michoacán and Morelos, breeding birds will initially be vaccinated; in Coahuila parent stock and breeders, while in Puebla and Querétaro, breeders and commercial layers will be immunized," according to Senasica officials. The intention is to apply about 210 million monthly vaccinations.

The National Veterinary Biological Production Agency of Mexico, Pronabive, is currently manufacturing all doses of vaccine to immunize birds.
