Superbug genes are getting into soil and water - will humans be next?Exclusive from New Scientist magazine

Farmers should stop using antibiotics as growth promoters, say researchers
in the US. They have uncovered evidence of a new route by which dangerous
antibiotic resistance genes can spread.
There is already strong evidence that feeding animals antibiotics can lead to
the emergence of resistant strains of gut bacteria such as salmonella, which
can then be passed on to people in food or through direct contact with
animals.
Now microbiologist Rustam Aminov of the University of Illinois at Urbana-
Champaign and his colleagues have discovered that bacteria in the soil and
groundwater beneath farms seem to be acquiring tetracycline resistance
genes from bacteria originating in pigs' guts.
