(NDAgConnection.com) – The U.S. Department of Agriculture says the top 10 importers of U.S. poultry have put some restrictions in place — largely banning chicken and turkey products from specific counties or regions in the U.S. Seven years ago, several countries banned poultry from the entire U.S. because of a bird flu outbreak.

According to Farms.com, more than 80 countries have put restrictions on imports of U.S. poultry products out of fear of bird flu spreading from American farms to their shores.

During the bird flu outbreak of 2014-2015, roughly half as many countries barred U.S. poultry. But those bans applied to any American poultry. This time, more nuanced trade policies parse their import restrictions to poultry from specific counties or regions in the U.S. where a highly contagious form of bird flu has been detected.

“There is a large reduction in the size of restricted zones from past outbreaks,” Mike Stepien, a spokesman for the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service, wrote in an email to Harvest Public Media. “Previously, several countries restricted the entire United States, and many countries implemented state-wide restrictions.”

Stepien said Argentina, South Korea and Thailand have banned live poultry from the entire U.S., but no countries have put restrictions on the whole U.S. for poultry meat and meat products, as some did in the 2014-2015 outbreak.

The top 10 importers of U.S. poultry are Mexico, China, Canada, Cuba, Guatemala, Taiwan, the Philippines, Angola, Columbia and Vietnam. All have placed restrictions on U.S. poultry.
