Milk from the offspring of a cloned cow has been on sale in the UK, it was claimed today.

A dairy farmer who has asked to remain anonymous admitted that milk from a cow bred from a clone made up part of his daily production.

The Food Standards Agency who had not approved the use of the milk are investigating the claims. Under European laws, food and drinks produced from cloned animals mast pass rigourous safety tests before going on sale to the public.

A spokeswoman said: “Since 2007 the FSA interpretation of the law has been that meat and products from clones and their offspring are considered novel foods and would therefore need to be authorised before being placed on the market.

The agency has not received any applications relating to cloning and no authorisations have been made.

The agency will … investigate any reports of unauthorised novel foods entering the food chain.”
