I would start by saying that I agree with Dr. Komal. I am not up to date on the science, but I certainly respect him and his position, and I don't think he would make that comment to this committee without making sure of his facts. His point about the exposure is kind of the point I was trying to make, that in order to transmit a disease, you have to be near a sick animal to pick up that virus, and then move it.
Mr. Currie is right. Some of them move through the air and some of them can transfer really easily. I do not want to discount that there are some viruses that move like that, but certainly not all of them do. Generally you have to be pretty close and then move it through.
On the difference between an employee versus someone who comes onto the farm, the only thing I would say is that, generally, we expect employers to deal with their employees so that if there is a breach in following farm protocol, I would expect that it would be the farm manager or owner dealing with that, as opposed to using any kind of a tool such as this.
