They will and retest, but at the SUPER SUPER rare case you have it, yep they will all be wiped out, which sounds bad, but it is a super rare problem now, just because of this action.....so well worth it. If you had sick birds and started shipping and spread Pollurum/typhoid all over the place, it could get bad , quick again.
As for testing or not testing,
If selling your stock out of state, legally you are required to be certified, wheather you like it or not. If you are just wanting your own private flock, there's no need for it in my opinion.
