This has generated much concern among the Food Standards Agency (FSA) and many farmers.
But Britain's dairy industry keeps insisting that there is absolutely no danger. (they always say that)
A British dairyman, speaking anonymously, said that he was using milk from a cow bred from a clone as part of his daily production.
The farmer did not want his name to be disclosed because he feared Britons saw cloning as "distasteful" so buyers would stop taking his milk if they knew who he was.
(what does he think the public will do now?)
The FSA said, "The agency has not received any applications relating to cloning and no authorizations have been made."
They go on to say,"The agency will, of course, investigate any reports of unauthorized novel foods entering the food chain."
Peter Stevenson, from campaigners Compassion in World Farming, said he was "extremely concerned" at the report and called for an outright ban on the sale of food from cloned animals and their offspring.
But Dairy UK, which represents the industry in Britain, keeps insisting there was no danger.
"Milk and meat from the offspring of clones does not present any food safety risk," it said in a statement.
Here's an interesting commercial from CyClone Dairy:
