NAGOYA (Kyodo) Quail at another Aichi Prefecture farm have tested positive for a relatively weak form of bird flu, officials said Monday.
The case was found during testing at 24 farms near a quail farm in Toyohashi where the H7N6 substrain of bird flu virus was detected last week.
The Toyohashi Municipal Government said it was conducting further tests to determine the type of virus.
In line with the Domestic Animal Infectious Diseases Control Law, the city told nine farms within a 5-km radius not to move quail eggs, meaning they can't ship their products.
The city initially hoped to lift the ban on moving quail in the area Monday after culling some 260,000 birds at the farm where the virus was first detected. The dead birds will be buried on land owned by the farm.
The virus at the first farm was identified Sunday as the H7N6 subtype, and not H5N1, the form of the disease that can be deadly to humans.
