You are correct I had the number for MRSA and all microorganisms confused.

I can't find any numbers for 2010. The best I can offer is 5,500 MRSA
deaths/yr for 1999-2005 in the U.S..

I think it isn't mentioned because while it seems quite plausable, the
animal feed to human antibiotic resistance link isn't proven.
For NYT coverage where the risk is mentioned see:
"Now, after decades of debate, the Food and Drug Administration
appears poised to issue its strongest guidelines on animal antibiotics
yet, intended to reduce what it calls a clear risk to human health.
The guidelines, which are voluntary and will not have the binding
force of regulations, would end farm uses of the drugs simply to
promote faster animal growth and call for tighter oversight by

I think because of the way bacteria can exchange resistance genes
(very promiscuously via independent genetic elements called plasmids),
once a resistance gene exists in one species, it can rapidly migrate
to other species.
Second 80% of antibiotics used in this country are getting used on
animals, so if resistance is getting bred, it is likely to take place
in animals first.
Third low doses of antibiotics are used in animal feed, which sounds
like just the right recipe to breed antibiotic resistance.
And fourth antibiotic resistant bacteria have been shown to be present
on flies collected near poultry feeding areas, showing a route all of
this could be transmitted to humans:

Yes, this would be good, but I suspect expensive, and so from a cost
benefit perspective lower priority.

Yes, using antibiotics less is important. With the bulk of
antibiotics going to animal feed, I suspect that is probably where we
need to start.
