Fifth case of BSE in Japan traced to Isehara
Officials revealed that a fifth cow found infected with the disease in Japan had been raised at the farm. The farmer was questioned about the dates he started using a milk substitute fed to the third infected cow and suspected of causing the disease.
Officials hope to determine by the end of this month the chances of additional cases of infected cows.
Japan's first infected cow was found in September in Chiba Prefecture. In late November, two cows raised in Hokkaido and Gunma prefectures were also found to have the disease. The fourth infected cow was found on 11 May in Hokkaido.
