"There's a global campaign to force meat producers to rein in their use of antibiotics on pigs, chickens and cattle. European countries, especially Denmark and the Netherlands, have taken the lead. The U.S. is moving, haltingly, toward similar restrictions. Now the concerns about rampant antibiotic use appear to have reached China, where meat production and antibiotic use have been growing fast."
"Half of all the pigs in the world live in China — a consequence of the country's swelling appetite for pork. And like pork producers in many other countries, Chinese farmers have turned to antibiotics and other feed additives to control disease in their herds and also to make the animals grow faster.
The exact extent of antibiotic use in Chinese agriculture is unknown, because authorities don't monitor it. But researchers have sometimes found disturbingly high levels of antibiotic residues in manure from Chinese pig farms.
A study published Monday by the Proceedings of the National Academy of Sciences adds to evidence that antibiotic use by Chinese pork producers poses health risks. According to the study, manure from pig farms doesn't just contain antibiotic residues. It also carries high concentrations of bacteria that are resistant to antibiotics. This increases the risk that antibiotic resistance will move into bacteria that infect humans, and the resulting diseases will be more difficult to treat."
