The World Health Organisation has said Turkey is taking appropriate and satisfactory measures to handle an outbreak of bird flu.
However, another UN body, the Food and Agriculture Organisation, has warned that the virus could become endemic in the country.
Speaking at a news conference in Ankara, the WHO's European director, Marc Danzon, added, however, that there was still no evidence of human to human transmission of the virus.
A WHO team is visiting the country to try to determine how the outbreak spread so quickly from the far east of Turkey to provinces on the Black Sea a couple of hundred kilometres from the capital.
Officials said the disease has spread much faster there than anywhere else, with 15 confirmed cases of human infection in just a week.
A spokesman said it was possible the virus was now being transmitted more efficiently between bird and humans.
