Chinese antibiotic use 'threatening Australian food safety'

Scientists have warned that Australia could be importing superbugs in its food supply because of China's rampant use of antibiotics on farms. US scientists say antibiotics are in such heavy use on Chinese animal farms that it could lead to wide human antibiotic resistance on a vast scale.

A research team from Michigan State University carried out tests on manure from three large commercial pig farms in China. The researchers discovered large concentrations of genes which are capable of conferring resistance to all major classes of antibiotics. Those genes are being dispersed into the soil as the manure is re-used as fertiliser.
