This guidelines are just voluntary? What's the point? "'Our fear ... is that there will be no reduction in antibiotic use as companies will either ignore the plan altogether or simply switch from using antibiotics for routine growth promotion to using the same antibiotics for routine disease prevention,' said Steven Roach, senior analyst with advocacy group Keep Antibiotics Working."
My understanding with FDA guidelines is they are always "voluntary" only in name. Companies effectively have to comply or the FDA will crack down very hard on the company.
This is why it's a voluntary guideline.
