Taiwan and the Philippines have joined Japan and Mexico in imposing bans on poultry products from Missouri after an outbreak of H7N3 low-pathogenic avian influenza was found on a turkey farm in Polk County. USDA’s Food Safety and Inspection Service posted information on the agency’s Web site this morning.  Taiwan has indicated it is placing a ban on all imports of poultry and poultry products originating from the state loaded on board vessels on or after April 19.  The Philippines has announced it is placing a temporary ban on imports of all poultry products derived from birds raised or slaughtered in Polk County effective April 4.
