Tuberculosis is deadly in cows and has been a problem on UK farms for a long time. Now scientists in China think they may have found a solution - genetically modified cloned cows that can't catch TB.

Not everyone thinks this is the answer. The experiment only checked if blood taken from the modified cows was resistant to TB, rather than testing the cows themselves. Many scientists in the UK doubt this innovation will work on real farms.

Would you eat beef from genetically modified cows?


Unless the law is changed cloned cows won't be appearing on UK farms, as GM meat and dairy foods are currently banned.
