hau Devin, The new rule only covers antibiotics used in feed.
Changes include eliminating the growth promotion use of human medically important antibiotics and expanding the list of feed-grade antibiotics classified as Veterinary Feed Directive (VFD) drugs. Historically, a majority of feed-grade antibiotics used in or on animal feeds have been available to producers over-the-counter, without approval from a veterinarian. By Jan. 1, 2017 the FDA will move all human medically important feed-grade antibiotics to the VFD drug process.
This rule does not cover injectable antibiotics, so there is still that to contend with. It also only covers those antibiotics considered "Human Medically Important" so if the antibiotic is only considered for animal use, it is still allowed without regulation.
As far as soil is concerned, any antibiotic will have the effect of killing off the bacteria we desire to be thriving so we have soil instead of dirt. The purpose of antibiotics is to destroy bacteria, and they are quite good at doing their job.
