Antibiotics in Meat - are you for or ANTI?

First off - sorry about the pun, it's the first post and a bad way to start but I just had to do it.
As a Brit in the US I've been looking out for antibiotic (and hormone) free meat since I arrived here. Back in the EU it would seem strange to be buying products which included antibiotics (I think I've only taken them from the doctors 2 or 3 times in the last 10 years so why up the dose?)
I did manage to source it through farmers markets and certain 'up market' retailers but now see the big players advertising on their products in the major chains.
Is there a change happening over here through public concern or have they found a way to cut costs? I don't know but I for one am happy with the change.
