Four more UK farms face bird cull

Poultry on four new farms in the UK are to be culled today as tests are carried out to establish if they have been infected with the deadly H5N1 bird flu found in a flock of turkeys in East Anglia.

The birds are being slaughtered as a precautionary measure on four sites that are operated by the same company as the free-range rearing unit in Suffolk, at the centre of the outbreak.
