The National Agrifood Health, Safety and Quality Service of Mexico, Senasica, confirmed that Bachoco poultry farms in the Mexican state of Guanajuato have the highly pathogenic AH7N3 avian influenza virus, which is the same virus that previously affected the states of Jalisco and Aguascalientes.

According to a press release from the Secretariat of Agriculture, Livestock, Rural Development, Fisheries and Food, Sagarpa, Senasica reinforces the diagnostic activities and movement controls of birds and poultry products in the affected area in 13 state checkpoints on major routes.

Another five farms have been already affected, thus reaching a total of 12 farms with the virus. Ten of these are of broiler breeder hens and two of commercial layers. Nine in Dolores Hidalgo, one in Juventino Rosas, another in San Felipe Torres Mochas and one more in San Luis de la Paz, State of Guanajuato. In total, it is a population of about 1 million birds.


Among the activities that are being intensified is preventive vaccination.

Cleaning and disinfecting facilities and equipment of each of the affected farms have also begun. These farms are quarantined, and as established by international health protocols, culling is taking place. The number of birds that may be sacrificed will be determined with specific diagnoses that reveal the presence of avian influenza AH7N3. Additionally, verification of hatcheries will be conducted.

Jaime Crivelli, chairman of the board of the National Poultry Producers Association, told the newspaper Reforma that "although the outbreak is large for Bachoco, nationally it should not lead to any increase in the price of eggs, since the number of birds affected is not significant." The poultry producers' representative also ruled out an increase in chicken prices.
