• Resumen

  • The world's farmers are feeding an estimated 63,000 tonnes of antibiotics to chickens, pigs and cattle every year, encouraging the evolution of resistant bacteria, which have repeatedly been linked to human infections. The team behind the estimate--the first of its kind--also forecasts that antibiotic use will climb by 67 per cent to 106,000 tonnes by 2030. Most of the increase is expected to be in middle-income countries, but once resistant bacteria appear, they can spread around the world. The problem is worsening as people prosper and can afford to eat more meat and dairy. Such is the demand that, according to team member Tim Robinson of the International Livestock Research Institute in Nairobi, Kenya, the total biomass of the world's livestock now outstrips that of people.
