Bird flu outbreak hits 500,000 Mexican chickens Mexico's animal health agency says a bird flu outbreak at seven farms in central Mexico has affected as many as 582,000 chickens. The Agriculture Department says more than a half million birds were exposed, but the number that will have to be slaughtered has yet to be determined. An outbreak of the H7N3, a subtype of the bird flu virus, in western Mexico in 2012 led to the slaughter of more than 22 million hens and caused price increases in chicken and egg products. Worldwide: Health officials confirmed a 5-year-old girl in Cambodia had been diagnosed with the H5N1 virus on Feb. 7 Outbreak: Health officials in Indonesia were forced to burn culled ducks after an outbreak of bird flu on Feb. 6 But the department said Friday that the current outbreak has not affected the supply of chicken products. It said tests were continuing to determine the exact strain of virus involved in the outbreak, but said it did not affect humans. Mexico's nationwide flock amounts to 137 million birds. About 14,000 ducks at a German farm are being slaughtered following a bird flu outbreak. A federal laboratory confirmed on Friday the H5N1 virus was detected at the farm near Seelow, east of Berlin - the first such finding in Germany in more than three years. On Saturday, officials started slaughtering the farm's ducks. Local council spokesman Tobias Seyfarth told news agency dpa that all poultry within a one-kilometer (half-mile) radius of the facility will be kept under observation for the next 21 days, with owners told to keep their birds where they are and report any symptoms. The H5N1 virus normally spreads between sick poultry, but it can sometimes spread from poultry to humans. Fear: Ducks from a farm in eastern Germany were brought to be slaughtered following a bird flu outbreak at the facility A 3-year-old Cambodian girl has become the sixth person to die from bird flu in the country this year. Cambodia's Health Ministry and the World Health Organization said on Wednesday that the child was in contact with poultry in her village in southern Kampot province, where there were recent deaths among poultry. Cambodia has registered seven human cases this year of the virus, also called avian influenza, or H5N1. Only one has survived. A 4-year-old Indonesian boy died from bird flu, bringing the death toll to 160 in the country hardest-hit by the deadly virus, a health official said on Tuesday. He developed symptoms of a cold and fever on Nov. 30 and was treated at a public health center before being hospitalized the same day he died. It is believed that he became infected with the H5N1 virus after having direct contact with dead fowl around his house. It remains hard for people to catch, but experts fear it could mutate into a more deadly form that spreads easily from person-to-person. So far, most human cases have been linked to contact with infected poultry. The WHO says bird flu has killed 365 other people worldwide since surfacing in 2003.
