March 2 (Bloomberg) -- Japan’s agriculture ministry advised poultry farmers in the central part of the country to restrict shipments after a second case of bird flu was found on a quail farm.

It may take five days to determine the exact strain of avian influenza, Kazuo Kobayashi, an official at Aichi prefecture, said by telephone today. The capital of Aichi is Nagoya and the region is home to companies including Toyota Motor Corp.

The latest infection was in Toyohashi, less than 5 kilometers (3 miles) from a farm where the H7N6 strain of the virus was detected last week, according to a statement posted on the Web site of Japan’s farm ministry today. The Aichi government began culling about 259,000 quail at the first farm.

A pandemic flu of avian or other origin could kill 71 million people worldwide and lead to a “major global recession” costing $3 trillion, according to a worst-case scenario outlined by the World Bank in October.
