February 4, 2007By Sally Peck and agenciesUK TelegraphThe Government is preparing "very seriously" for the possibility of a human flu pandemic as officials battle to contain the first avian flu outbreak in the UK.Patricia Hewitt, the Health Secretary, spoke out as experts were continuing to slaughter 159,000 turkeys at a Bernard Matthews farm in Suffolk where the potentially deadly H5N1 strain, which can be transmitted to humans, was found yesterday.She said: "It is a very remote risk but if it did happen it could be very serious indeed."Officials have ordered poultry owners living within the 2,090 sq km restriction zone set up following the outbreak to bring their birds inside.Jill Korwin, assistant head of Trading Standards for Suffolk, said officers were using the National Poultry Register to identify owners and would also be relying on the general public to provide information about anyone who was not abiding by the regulations.The Department for Environment, Food and Rural Affairs surveillance of wild bird deaths is ongoing, and members of the public are being asked to report single deaths of ducks, geese and swans, or groups of 10 or more dead birds of any one species in a single area.The outbreak has sparked fears of a potentially devastating customer backlash on the £3.4 billion industry.There have been 271 confirmed bird flu cases in humans worldwide and 165 deaths since 2003, according to the World Health Organisation.
