Norway confirms first instance of mad cow disease
Norway reported its first ever case of mad cow disease yesterday, saying the instance was an isolated one and telling consumers it was still safe to eat beef and drink milk.
Tests at a British laboratory confirmed the disease, also known as bovine spongiform encephalopathy (BSE), in a 15-year-old cow, which had been slaughtered, the Norwegian Food Safety Authority said.
The case was atypical, meaning there had been no transmission through the feed supply and it was not related to any wider outbreak, the authority said.
Since BSE was first identified in Britain in 1986, strict controls have tempered the spread of the disease.
But after its emergence, scientists became concerned about possible links, via the consumption of contaminated tissue, between BSE and a human illness called Creutzfeldt-Jakob disease.
A new variant of Creutzfeldt-Jakob disease, nvCJD, killed dozens of people in Europe beginning in the mid-1990s.
Norwegian authorities said several other cows that had been in contact with the dead animal would also be slaughtered.
