EU officials have sought to reassure the public about preparations for dealing with a bird flu outbreak.
It comes as Foreign and Agriculture Ministers discuss the situation at an emergency meeting in Luxembourg.
The EU Health Commissioner, Markos Kyprianou, said all the necessary steps had been taken.
Mr Kyprianou also said the presence of bird flu in Europe did not increase the risk of a human influenza pandemic.
The meeting takes place a day after Greece reported the first case of bird flu in an EU member state. More tests are taking place on dead birds in Romania and Croatia.
The Chairman of the Luxemburg meeting, Britain's Foreign Secretary Jack Straw, said its purpose was to reassure citizens that every precaution was being taken to prevent the outbreak from mutating into a pandemic that could kill humans.
Earlier, the European Commission called on member states to stockpile anti-viral drugs to prepare for the possibility of a pandemic, but cautioned against alarm.
However, the World Health Organization has warned the public against panic buying of an anti-viral drug. The UN body has stressed that the drug, Tamiflu, can only be used to treat people who have caught the virus already.
Dr Mike Ryan, head of the WHO's pandemic alert unit, said the drug could be essential in containing an outbreak.
