That is a good point. In dairy, part of the biosecurity module of our proAction program is that you must have a sign on the entrance to your facility that states that there's biosecurity in place and that someone can't simply enter the building; they need to have permission. Then there's contact information given if they want to. Well, if they do go in, they know very clearly then that they are out of bounds and are going somewhere they should not be, and they know why they shouldn't be there. That is for all dairy facilities across the country.
