That 10% may not be accurate. In any case, the EU actually only banned the use of antibiotics as growth promoters, but not as 'preventative medicine'. Furthermore, the level of reporting on actual EU antibiotic use is somewhat spotty - especially given the multinational nature of it all. At best, the ban on growth promotion resulted in an ~10% decrease in antibiotic use. The massive scale on which preventative antibiotic use is applied likely minimized any negative impacts the removal of growth promotion had on actual growth rates. http://www.ciwf.org.uk/includes/documents/cm_docs/2011/a/antibiotics_in_animal_farming.pdf http://www.ciwf.org.uk/includes/documents/cm_docs/2011/a/ant...
