European officials say Wednesday tests have confirmed the deadly H5N1 strain of avian flu has spread to Croatia.

The H5N1 strain is the one that has killed thousands of birds and more than 60 people in Asia.

Several wild swans were found dead in Croatia last week and Croatian authorities began slaughtering flocks of local poultry once it was confirmed that the wild birds died of bird flu. Samples from the swans were sent to England for testing, where scientists confirmed they had the H5N1 strain.

A European Union spokesman said only food from healthy animals will be allowed to reach consumers. The EU has banned the import of live birds, poultry meat and feathers from Croatia and other countries where bird flu has been found.
