The Philippines has imposed a ban on the importation of birds and poultry products from Michigan, USA, in response to an outbreak of bird flu. The ban, which includes poultry meat, day-old chicks, eggs, and semen, was issued by Agriculture Secretary Francisco Tiu Laurel Jr. following an official report from the US Chief Veterinary Officer about the outbreak of the H5N1 subtype of avian influenza in Michigan. The ban is part of a bilateral agreement between the Philippines and the US, which mandates a state-wide ban if three or more counties are affected by avian flu.
