Czechs find bird flu at two more poultry farms

PRAGUE, July 11 (Reuters) - Vets found an unidentified type of H5 bird flu virus at two Czech farms with 71,000 poultry, bringing the number of outbreaks at farms to four, the State Veterinary Authority (SVS) said on Wednesday.
The SVS said it knew the virus found at the two new farms was of the H5 strain, but had not confirmed it was the H5N1 form, which can be fatal to humans.
The Czechs found their first bird flu case, which involved the lethal H5N1 strain, at a turkey farm in the eastern part of the country in June.
The two farms where the disease was reported on Wednesday are within a 3-km (1.9-mile) protective zone around another farm where H5N1 was found.
"We identified the virus during monitoring before the disease had broken out, which is good because it limits the chances of a further spread," SVS spokesman Josef Duben said.
Poultry at both farms would be slaughtered, he added.
Duben said standard 3-km protection and 10-km surveillance zones would be expanded to include the neighbourhood of the two farms.
