British farms at risk of bird flu spread

LONDON (Reuters) - Controls will probably prevent the large-scale spread of bird flu from one farm to another in Britain but there is still a significant chance that the virus will escape, researchers said on Wednesday.

Using data collected on poultry farms, feed mills and slaughter houses, the researchers ran millions of computer simulations to calculate the potential impact of the H5N1 avian influenza virus striking Britain's poultry industry.
