Article from BBC
The government has been urged to speed up its research into Variant CJD - the human form of mad cow disease.
It follows news that more than 460 people in Northern Ireland are being warned that they could have been exposed to vCJD through blood plasma products.
The Department of Health said on Tuesday that it was writing to 464 patients to explain they were potentially at a small increased risk of infection.
