Do you want superbugs with that?

That's the title of an article at On Earth, dealing with a lawsuit being brought against the FDA for the therapeutic use of antibiotics - i.e. giving them to farm animals in low-doses to make them grow faster. It seems to be responsible for a rise in the prevalence of superbugs, which kill 70,000 people per year in the US.

The article had an interesting quote from the Nobel Prize acceptance speech of Alexander Fleming, discoverer of penicillin:

There is a danger that the ignorant man may easily under-dose himself and by exposing his microbes to non-lethal quantities of the drug make them resistant

It seems that that's just what's happening and what's also currently legal.
