獸醫實驗研究所（Veterinary Laboratories Agency）針對養殖場死亡的火雞進行抽樣檢查後，證實雞隻血液中確含有H5N1型禽流感病毒。
Britain's first case of H5N1 avian influenza has been confirmed by government veterinarians. At least 2,500 turkeys died of the disease last week at a farm in Suffolk.
The Bernard Matthews farm near Upper Holton held 159,000 turkeys housed in 22 sheds, all of which have now been culled to prevent further spread of the highly pathogenic disease.
Tests from the Veterinary Laboratories Agency have confirmed that the sample from the turkeys found dead on the farm did contain the H5N1 avian flu virus.
This is the viral strain that has been responsible for 271 human cases of bird flu worldwide and a total of 165 deaths. In addition, hundreds of millions of chickens, ducks and turkeys have been killed by the disease or culled to prevent its spread.
The first sign of the outbreak occurred last Tuesday when 55 turkey chicks died and 16 had to be killed because they were sick. At least 185 more died the following day.
The State Veterinary Service is enforcing a Protection Zone of three kilometers (two miles) and a Surveillance Zone of 10 km (six miles) around the premises where movement restrictions will be imposed and poultry must be isolated from wild birds.
The Health Protection Agency has advised that, despite this incident, the current level of risk to humans from H5N1 remains extremely low. The UK has become Europe's third country infected by H5N1 during the current winter season. Outbreaks have been reported in Hungary on January 24 and in Krasnodar, Russia on January 29.
