If you click through to the report there are lots of numbers:<p><a href="http:&#x2F;&#x2F;www.fda.gov&#x2F;downloads&#x2F;ForIndustry&#x2F;UserFees&#x2F;AnimalDrugUserFeeActADUFA&#x2F;UCM231851.pdf" rel="nofollow">http:&#x2F;&#x2F;www.fda.gov&#x2F;downloads&#x2F;ForIndustry&#x2F;UserFees&#x2F;AnimalDrug...</a><p>Most of the antibiotics used for feed are ionophores and tetracyclines. Ionophones aren&#x27;t used in humans but are only about 40% of the antibiotics used in feed. They are added to cattle feed because they cut down on illness caused by feeding grain (bloat is crazy, consider this a risky click: <a href="http:&#x2F;&#x2F;i.imgur.com&#x2F;GfPvtBx.jpg" rel="nofollow">http:&#x2F;&#x2F;i.imgur.com&#x2F;GfPvtBx.jpg</a> ).<p>So most of the resistance concern would be with tetracyclines, where resistance is already a problem for many human infections.<p>The use of medically useful antibiotics as a feed additive should be stopped. I think it is harder to say that about ionophores.
