The European Commission on Monday banned all imports of feathers and live birds from Turkey into the 25-nation European Union after Turkey confirmed an outbreak of the highly contagious avian influenza.

But Turkish experts battling the disease played down fears of the kind of epidemic caused by the H5N1 virus, which has killed millions of birds and 65 people in Asia since 2003. The H5N1 virus is the most deadly of a number of known versions of bird flu.

The commission said it was taking no steps at the moment over a suspected outbreak of bird flu in Romania.

E.U. veterinary officers will meet in Brussels on Wednesday, when the results of bird flu tests in Romania and Turkey should be known. They could decide on further trade restrictions and tougher E.U. action.

The bloc's health and consumer protection commissioner, Markos Kyprianou, said in a statement that it was unclear whether the Turkish strain was the same as the one killing birds in Asia.

Turkey has culled about 3,000 turkeys and chickens since reporting its first outbreak of avian flu at a farm in the district of Manyas, near the Aegean and Marmara seas.

It has imposed a two-mile quarantine zone around the farm, where 1,870 turkeys died of the disease last week. Teams of veterinary experts in white overalls and gloves are hurriedly burying the slaughtered birds in lime-drenched pits.

"The precautionary measures are continuing, but this outbreak of disease is not an epidemic," said Arif Zorlu, a veterinary surgeon. "It is not spreading at the moment."

Cemil Cicek, a government spokesman, said there were no reports of other outbreaks of the disease in Turkey.

Romania was also conducting a widespread cull after detecting an outbreak in the Danube delta. Neighboring countries have announced bans on imports pending further investigation of the outbreak.
