Japan reported their first case of avian influenza of 2018 on January 11 when 55 infected chickens were found on a farm in western Kagawa.
Since the 55 birds were tested positive with a highly pathogenic strain of avian influenza, the local authorities decided to cull the remaining 92,000 chickens on the farm to prevent spreading of disease. Farms within a ten kilometer radius of the infected site are restricted from moving any poultry products including eggs out of the area.
Despite the biosecurity measures, Taiwan issued a temporary ban on all Japanese poultry products due to the risk of disease for four days. According to Taiwan News, the ban was from in place from January 13 – 15.
