That's correct, and this is one of the things that comes out in the study.
It isn't just by antibiotic use that you develop resistance. That resistance is endemic out there. It comes in the environment. That's why from a management perspective, for example, for all of our flocks we clean out all the litter, take it down, clean, and disinfect the barn, because we're trying to make sure the environment is good and we don't get resistance building up from one flock to the next flock.
So it isn't just in the use aspect; it's also management practices and our on-farm food safety program. We're tackling this from as many different perspectives as we can.
