The outbreak of bird flu detected in the central Mexican state of Guanajuato is confined to 12 farms that have more than 1 million chickens, the Senasica national agricultural health service reported on Monday.
The agency said in a press release that 10 of the poultry farms are chicken-fattening operations and two produce eggs for human consumption. Senasica, which is an agency under the control of the Agriculture Secretariat, said that all the affected farms are owned by the Bachoco company. Last Friday, authorities decreed a health emergency due to an outbreak of avian flu on seven Bachoco farms in Guanajuato, where some 582,000 domestic fowl exposed to the virus could be slaughtered to eradicate it, officials said.
