Increased antibiotic use in meat could create drug-resistant 'super bugs'

McDonald's has pledged to stop treating chicken with human antibiotics, but antibiotic use in meats is still on the rise. Reuters reports that across the globe, antibiotic use in meats could increase by two-thirds by 2030 — and that will have serious health consequences for humans.

A new study by researchers at Princeton, published in the journal Proceedings of the National Academy of Sciences, warns that developing countries using antibiotics in meat could create drug-resistant "super bugs" that affect the entire planet.

The researchers note that in China, Brazil, India, and Russia, antibiotic use in animals could double between 2010 and 2030. China's livestock alone could soon be responsible for almost a third of the world's antibiotics.
