Authorities in Britain are investigating claims that milk from the offspring of a cloned cow has been on sale.
Reports have emerged in the media of a dairy farmer admitting using the milk, without making it clear it came from a cloned cow.
But some experts claim the milk is perfectly safe.
Dr Brendan Curran, a geneticist at Queen Mary’s University in London said: “I don’t see any reason why we should not have milk from cloned animals. The evidence in America for many years where they have been analysing the products of both meat and milk from cloned animals is that it’s identical to normally produced milk and eggs, uh, milk and meat.”
Farming campaigners have voiced what they call “extreme concern” over the reports.
The Food Standards Agency said it would investigate.
It says it has not made any authorisations for the use of cloned milk, and has not been asked to do so.
It is also reported the anonymous farmer at the centre of the claim has been selling embryos from the same cow to breeders in Canada.
