Japanese branches of US burger giant McDonald's are pulling chicken products from their menu as stocks of chicken dwindled following the import ban on US chicken. The ban was imposed 18 March after an episode of bird flu in Virginia. While bird flu poses no risk to human health, and indeed can only be passed on by live birds, Japan is keen to be seen to act swiftly and forcefully after it was accused of a slow and careless response to an outbreak of BSE.
