Farmers must be prevented from using powerful antibiotics on animals reared for food, the World Health Organisation (WHO) has warned, because of the serious risks to human health that result.
New guidelines from the global body suggest farmers should stop using any antibiotics routinely to promote growth and prevent disease in animals that are otherwise healthy, a common practice in some parts of the world, including Asia and the US. Such routine use is banned in Europe, though campaigners fear the rules are sometimes flouted.
Using antimicrobial medicines on farm animals is one of the leading causes of the rise of superbugs, resistant to all but the strongest antibiotics. Medical authorities warn that the antibiotics available to treat even relatively minor human diseases are running out because of the rapid rise of such resistance.
