(Adds comment from Mexican agricultural sanitation authority)
PARIS/MEXICO CITY, May 4 (Reuters) - Mexico has reported an outbreak of the highly contagious H7N3 bird flu virus on a commercial farm in the state of Jalisco, the World Organisation for Animal Health (OIE) said on Thursday, citing a report from Mexico's agriculture ministry.
The virus, which does not pose a serious danger to people, was detected among laying hens in a flock of 15,000 birds that had been vaccinated and did not show any clinical signs of the disease, the Paris-based OIE said in a notification.
The farm, located in the town of Tepatitlan de Morelos, is under quarantine and the birds have been sent to a slaughterhouse near the site, it said.
Mexico's agriculture sanitation authority, SENASICA, said the outbreak occurred in the same area where the virus was detected in 2012 and was discovered as part of a supervision program aimed at freeing the country of the disease.
Mexico is a major chicken exporter.
In March, a highly pathogenic strain of bird flu was found in a chicken breeder flock on a Tennessee farm contracted to Tyson Foods Inc, the first discovered in the United States this year.
Different strains of avian flu have been detected across Asia, Europe, Africa and in the United States in recent months, leading to the culling of millions of birds and a flurry of import restrictions on eggs and chicken meat.
