CELAYA, Mexico – SENASICA, the Mexican Sanitary Authority, confirmed the presence of avian influenza H7N3 at some farms owned by Industrias Bachoco, the company said.

All the affected farms are in the state of Guanajuato and are located in the same region, according to Bachoco, a leading poultry processor in Mexico. The company said it is cooperating with sanitary authorities to control the outbreak. Bachoco has started a vaccination program, among other measures. SENASICA said the outbreak is not a human health risk, and that Mexico’s poultry supply is not at risk, according to Bachoco.

“Bachoco continues to reinforce biosecurity measures across all of its facilities and is analyzing further steps to mitigate any possible negative effects,” the company said in a statement.
